Abstract
Stimulator of interferon genes (STING)-dependent signaling is requisite for effective anti-microbial and anti-tumor activity. STING signaling is commonly defective in cancer cells, which enables tumor cells to evade the immunosurveillance system. We evaluate here whether intrinsic STING signaling in such tumor cells could be reconstituted by creating recombinant herpes simplex viruses (rHSVs) that express components of the STING signaling pathway. We observe that rHSVs expressing STING and/or cGAS replicate inefficiently yet retain in vivo anti-tumor activity, independent of oncolytic activity requisite on the trans-activation of extrinsic STING signaling in phagocytes by engulfed microbial dsDNA species. Accordingly, the in vivo effects of virotherapy could be simulated by nanoparticles incorporating non-coding dsDNA species, which comparably elicit the trans-activation of phagocytes and augment the efficacy of established cancer treatments including checkpoint inhibition and radiation therapy. Our results help elucidate mechanisms of virotherapeutic anti-tumor activity as well as provide alternate strategies to treat cancer.

Abstract
A 31-year-old primigravida, with spontaneous singleton pregnancy, presented in 21 weeks of gestation with abdominal pain. Abdominal ultrasound (USS) and Magnetic Resonance Imaging (MRI) showed a 12 × 14cm large complex lesion arising from the right ovary suspicious for an ovarian malignancy. The radiological staging demonstrated no further metastatic disease; however, it also revealed a 6 cm lesion in the contralateral ovary, consistent with a dermoid cyst. After tumour board discussion the patient underwent a mid-line laparotomy with right oophorectomy, cytology, and peritoneal and omental staging, under oral tocolysis with indomethacin. The left presumed ovarian dermoid was left in situ to avoid additional surgical and obstetrical morbidity. Histology confirmed a grade 3 immature teratoma with primitive neuroepithelium focally present on the capsular surface and atypical cells in the cytology amounting to a stage 1 C2 disease at least. Due to high-risk disease, she was offered adjuvant treatment. The patient received one cycle of intravenous paclitaxel, etoposide, and cisplatin chemotherapy, in an adjuvant setting. She underwent an elective caesarean section at 36 weeks, with the safe delivery of a healthy baby girl. After 6 weeks of her delivery, she received three further cycles of etoposide, and cisplatin to complete her course of adjuvant chemotherapy. Three months after the last chemotherapy cycle, she underwent a laparoscopic removal of the left ovarian dermoid that had increased in size to 8 cm. Final histology revealed no immature elements. To this point, 2 years after initial diagnosis, both mother and child are healthy with no long-term complications. The patient has resumed her normal menstrual cycle and being in remission, she wishes soon to try for a second child. To our knowledge, this is the only reported case of ovarian immature teratoma in pregnancy treated successfully with surgery and adjuvant iv paclitaxel, etoposide, and cisplatin chemotherapy regime.

Abstract
Dysregulation of the Notch signaling pathway, which is highly conserved across species, can drive aberrant epigenetic modification, transcription, and translation. Defective gene regulation caused by dysregulated Notch signaling often affects networks controlling oncogenesis and tumor progression. Meanwhile, Notch signaling can modulate immune cells involved in anti- or pro-tumor responses and tumor immunogenicity. A comprehensive understanding of these processes can help with designing new drugs that target Notch signaling, thereby enhancing the effects of cancer immunotherapy. Here, we provide an up-to-date and comprehensive overview of how Notch signaling intrinsically regulates immune cells and how alterations in Notch signaling in tumor cells or stromal cells extrinsically regulate immune responses in the tumor microenvironment (TME). We also discuss the potential role of Notch signaling in tumor immunity mediated by gut microbiota. Finally, we propose strategies for targeting Notch signaling in cancer immunotherapy. These include oncolytic virotherapy combined with inhibition of Notch signaling, nanoparticles (NPs) loaded with Notch signaling regulators to specifically target tumor-associated macrophages (TAMs) to repolarize their functions and remodel the TME, combining specific and efficient inhibitors or activators of Notch signaling with immune checkpoint blockers (ICBs) for synergistic anti-tumor therapy, and implementing a customized and effective synNotch circuit system to enhance safety of chimeric antigen receptor (CAR) immune cells. Collectively, this review aims to summarize how Notch signaling intrinsically and extrinsically shapes immune responses to improve immunotherapy.

Abstract
Longstanding evidence implicate glioma stem-like cells as the main drivers contributing toward glioblastoma (GBM) therapy resistance and tumor recurrence. Although oncolytic herpes simplex virus (oHSV) viral therapy is a promising biological therapy recently approved for melanoma (in the United States and Europe) and GBM (in Japan); however, the impact of this therapy on GBM stem-like cells (GSCs) is understudied. Here we show that post-oHSV virotherapy activated AKT signaling results in an enrichment of GSC signatures in glioma, which mimics the enrichment in GSC observed after radiation treatment. We also uncovered that a second-generation oncolytic virus armed with PTEN-L (oHSV-P10) decreases this by moderating IL6/JAK/STAT3 signaling. This ability was retained in the presence of radiation treatment and oHSV-P10-sensitized intracranial GBM to radiotherapy. Collectively, our findings uncover potential mechanisms to overcome GSC-mediated radiation resistance via oHSV-P10.

Abstract
High-mobility group box 1 (HMGB1) is a damage-associated molecular pattern (DAMP) molecule that plays an important role in inflammation and tumorigenesis. Receptor for advanced glycation end products (RAGE) is one of the major receptors to which extracellular HMGB1 binds to mediate its activity. RAGE is highly expressed on the endothelial cells (ECs) and regulates endothelial permeability during inflammation. Here, we introduced the endogenous secretory form of RAGE (esRAGE) as a decoy receptor for RAGE ligands into an oncolytic herpes simplex virus 1 (oHSV) (OVesRAGE), which, upon release, can function to block RAGE signaling. OVesRAGE significantly decreased phosphorylation of MEK1/2 and Erk and increased cleaved PARP in glioblastoma (GBM) cells in vitro and in vivo. oHSV-infected GBM cells co-cultured with ECs were used to test OVesRAGE effect on EC activation, vessel leakiness, virus replication, and tumor cell killing. OVesRAGE could effectively secrete esRAGE and rescue virus-induced EC migration and activation. Reduced EC activation facilitated virus replication in tumor cells when co-cultured with ECs. Finally, OVesRAGE significantly enhanced therapeutic efficacy in GBM-bearing mice. Collectively, our data demonstrate that HMGB1-RAGE signaling could be a promising target and that its inhibition is a feasible approach to improve the efficacy of oHSV therapy.

Abstract
BACKGROUND Mammalian cells have developed multiple intracellular mechanisms to defend against viral infections. These include RNA-activated protein kinase (PKR), cyclic GMP-AMP synthase and stimulation of interferon genes (cGAS-STING) and toll-like receptor-myeloid differentiation primary response 88 (TLR-MyD88). Among these, we identified that PKR presents the most formidable barrier to oncolytic herpes simplex virus (oHSV) replication in vitro. METHODS To elucidate the impact of PKR on host responses to oncolytic therapy, we generated a novel oncolytic virus (oHSV-shPKR) which disables tumor intrinsic PKR signaling in infected tumor cells. RESULTS As anticipated, oHSV-shPKR resulted in suppression of innate antiviral immunity and improves virus spread and tumor cell lysis both in vitro and in vivo. Single cell RNA sequencing combined with cell-cell communication analysis uncovered a strong correlation between PKR activation and transforming growth factor beta (TGF-ß) immune suppressive signaling in both human and preclinical models. Using a murine PKR targeting oHSV, we found that in immune-competent mice this virus could rewire the tumor immune microenvironment to increase the activation of antigen presentation and enhance tumor antigen-specific CD8 T cell expansion and activity. Further, a single intratumoral injection of oHSV-shPKR significantly improved the survival of mice bearing orthotopic glioblastoma. To our knowledge, this is the first report to identify dual and opposing roles of PKR wherein PKR activates antivirus innate immunity and induces TGF-ß signaling to inhibit antitumor adaptive immune responses. CONCLUSIONS Thus, PKR represents the Achilles heel of oHSV therapy, restricting both viral replication and antitumor immunity, and an oncolytic virus that can target this pathway significantly improves response to virotherapy.

Abstract
BACKGROUND Ovarian clear cell carcinoma (OCCC) accounts for approximately 8-10% of epithelial ovarian cancers in the United States. Although it is rare, OCCC usually presents with treatment challenges and the overall prognosis is far worse than high grade serous ovarian cancer HGSOC. The objective of this study was to examine the therapeutic relevance of combining oncolytic virus with cisplatin for ovarian cancer clear cell carcinoma (OCCC). RESULTS We identified that TMEM205, a recently discovered transmembrane protein, contributes to chemoresistance in OCCC cells via the exosomal pathway. Mechanistically, TMEM205 undergoes ligand-independent constitutive endocytosis and co-localizes with Rab11 to contribute to the late recycling endosomes in a clathrin-independent manner. Further, we observed that oncolytic virus (oHSV) pretreatment followed by treatment with cisplatin decreases TMEM205 expression and sensitizes cells to cisplatin in a synergistic manner in OCCC cells. TMEM205 interacts with glycoprotein-C of oHSV post-infection; both of these proteins undergo ubiquitination and ultimately get shuttled outside the cell via exosomes. Thus, we demonstrate the mechanotransduction pathway of TMEM205-mediated chemoresistance along with targeting this pathway using oHSV and cisplatin as a powerful therapeutic strategy for OCCC. oHSV combination with cisplatin inhibits OCCC tumor growth in vivo in immunodeficient and immunocompetent mice models. CONCLUSION Our results suggest that the combination of oHSV and cisplatin in immunocompetent as well as immune deficient OCCC tumor bearing mice reduces overall tumor burden as well as metastatic disease thereby providing survival benefit. Additionally, the detection of TMEM205 in exosomal cargo early in OCCC development has potential to be exploited as a biomarker.

Abstract
Glioblastoma (GBM) is the most aggressive brain malignancy, which despite continuing worldwide efforts to develop new therapies, remains a deadly disease with limited treatment options. The asparagine hydroxylase factor inhibiting HIF (FIH1) is located in chromosome 10q24, a region often deleted in GBM, suggesting a tumor protective role. FIH1 has been implicated in GBM as an inhibitor of HIF1α-mediated transcription of VEGF-A, leading to decreased angiogenesis. We previously showed that oncolytic HSV (oHSV) infection reduces the expression FIH1 via a virus encoded miRNA. Furthermore, we have found that FIH1 also negatively regulates NOTCH signaling, which is elevated following oHSV treatment. Thus, we hypothesize that FIH1 reconstitution in tumors will block pro-tumorigenic NOTCH and HIF1α signaling. Using FIH1-overexpressing GBM cells we observed a reduction in vascular permeability, measured by intravital imaging, and decreased expression of angiogenesis markers. In vivo, combination of FIH1 overexpression with oHSV treatment resulted in enhanced survival in mice bearing intracranial GBM tumors. Furthermore, FIH1 overexpression correlated with the enrichment of genes associated with oxidative phosphorylation and ROS pathways, suggesting the potential for multi-modality therapeutic strategies.

Abstract
The host immune system has developed many mechanisms to defend against and clear virus infections, including PKR, cGAS-STING and TLR-MyD88 signaling pathways. Compromised anti-viral mechanisms in tumor cells allows for infection, replication and lysis by oncolytic viruses. However, compromised antiviral mechanisms, together with immune cells and the tumor microenvironment (TME), limit the sensitivity of oncolytic virus in tumor cells. We generated a novel oncolytic Herpes simplex virus, oHSV-shPKR which disables tumor-intrinsic PKR signaling. oHSV-shPKR significantly increases oHSV infection and lysis in both oncolytic virus-resistant and sensitive glioblastomas (GBMs). Infection of oHSV-shPKR in GBMs induces G2/M cell cycle arrest and inhibits tumor cell growth. oHSV-shPKR increases activation of antigen presentation cells through type I interferon signaling activation and its immune-stimulatory function to increase tumor-antigen specific CD8 T-cell expansion, including cytotoxic T lymphocytes. Preclinical studies showed that oHSV-shPKR intra-tumoral injection significantly inhibits human GBM patient derived xenograft (PDX) tumor growth in immune-deficient NSG mice and murine orthotopic GBM tumor growth in immunocompetent mice. The results demonstrate that the novel oHSV-shPKR has the potential to be used in clinical applications for both oHSV-resistant and sensitive GBM treatment.

Abstract
Glioblastoma Multiforme (GBM) is the most aggressive malignant primary brain tumor and has abysmal 5-year overall survival. With the approval of oHSV Imlygic by FDA for metastatic melanoma and more recently, conditional approval of G47Δ, marketed by Daiichi Sankyo for GBM treatment in Japan, oncolytic viral therapy has emerged as a promising biological approach to treat solid tumors. Our laboratory has previously shown that oHSV expressing long isoform of PTEN (PTENα), HSV-P10, has faster kinetics of virus replication associated with enhanced killing of the glioma cells compared to control HSV. Additionally, HSVP-10 is known to increase mitochondrial membrane potential and cellular ATP production while stimulating anti-tumor immune responses in vivo. RNA sequencing of primary GBM cells infected with HSV-P10 shows altered metabolic pathways relative to control HSV infected cells. 13C metabolic flux analysis in uninfected and control or HSV-P10 infected primary GBM cells reveals that while HSV-P10 infection shuttles most of the glutamine towards citrate by reductive carboxylation of α-ketoglutarate resulting in faster replication of HSV-P10, simultaneously it increased glucose utilization and shuttling towards TCA cycle. This corroborates with enhanced mitochondrial activity leading to increased oxidative phosphorylation and increased cellular and extracellular ATP (eATP). eATP binds to purinergic receptors on tumor and immune cells and boosts anti-tumor immunity. However, the use of extracellular ATP in cancer therapy is limited owing to its short half-life and rapid hydrolysis by ectoenzymes CD39 and CD73 into immune-suppressing adenosine. CD73 carries out the conversion of AMP to adenosine, making it a key regulator of this pathway. Using mice with CD73 knocked out globally (CD73KO), we show that combination of CD73 inhibition with HSV-P10 imparts significant survival benefit compared to WT mice treated with HSV-P10. Our findings will further the understanding of oHSV therapy and the role of the ATP/adenosine in the tumor microenvironment.

Abstract
Abstract
The tumor microenvironment (TME), including the non-tumor cells and the extracellular matrix (ECM) plays a crucial role in tumor progression and metastasis. Hyaluronic acid (HA), the major glycosaminoglycan present in brain ECM, has long been associated with the progression and invasiveness of brain tumors. HA signals primarily thorough CD44, an adhesion/homing receptor leading to the induction of cellular AKT, MEK and HIF signaling, thereby promoting tumor cell proliferation, aggressiveness and therapy resistance. While HA in the ECM has been shown to interfere with infection and spread of oncolytic viruses, the impact of tumor-ECM interaction induced signaling on oncolytic virotherapy is heavily understudied. RNA sequencing and gene set enrichment analysis of glioma cells infected with an oncolytic Herpes Simplex Virus-1 (oHSV) demonstrate an enrichment of pathways related to tumor-ECM interaction. Immunostaining of brain sections from intracranial tumor bearing mice also reveals increased HA after oHSV treatment. Our results further demonstrate that HA/CD44-mediated signaling inhibits virus replication in vitro. Herein, to evaluate the impact of blocking tumor-ECM interactions without altering the secreted ECM, we created oHSV-sCD44, an oHSV that encodes for extracellular soluble CD44 (sCD44) that can function as a dominant negative receptor for membrane bound CD44. oHSV-sCD44 significantly reduces the stemness of glioblastoma stem cells (GSCs), induces DNA damage and sensitizes the GSCs to radiation therapy. Intra-tumoral injection of oHSV-sCD44 into patient-derived primary GBM xenograft model significantly inhibits tumor growth accompanied by reduced stemness and decreased HA expression, and increased oHSV replication and tumor cell lysis in TME. Moreover, blocking HA-CD44 signaling with a single dose of oHSV-sCD44 in murine glioma syngeneic model induces the development of a significant anti-tumor immune response with enhanced T cell infiltration. Collectively, our findings implicate oHSV-sCD44 as a potential oncolytic and immune-stimulating anticancer therapeutic.

Abstract
INTRODUCTION
The median survival of Glioblastoma (GBM) patients is less than two years with the standard of care of maximal surgical resection, radiation, and temozolomide (TMZ) chemotherapy. Protein Arginine Methyltransferase 5 (PRMT5), which regulates cellular functions by symmetrically di-methylating arginine residues, is overexpressed in GBM. Inhibiting PRMT5 induces apoptosis in differentiated and senescence in stem-like GBM tumor cells. We inhibited PRMT5 in GBM neurospheres to determine if PRMT5 inhibition would enhance TMZ’s antitumor effect.
METHODS
We depleted PRMT5 activity, in vitro, using target-specific siRNA or LLY-283 and combined these with TMZ treatment. We evaluated the antitumor effect of this combination using cell viability assay, cell cycle analysis, apoptosis assay, and western blot.
RESULTS
TMZ reduced the viability of GBMNS with PRMT5 knockdown significantly more than the viability of PRMT5 intact GBMNS. The combination of TMZ and PRMT5 knockdown elevated the expression of cleaved caspase 3 and caspase3/7 indicating that PRMT5 knockdown enhanced the apoptotic effects of TMZ. Cell cycle analysis showed that depleting PRMT5 abrogated TMZ-induced G2/M cell cycle arrest. Further, treatment of PRMT5-depleted GBMNS with TMZ increased ɣ-H2AX expression compared PRMT5 intact GBMNS treated with TMZ, suggesting that PRMT5 depletion enhanced TMZ-induced DNA damage. PRMT5 knockdown also inhibited the symmetric di-methylation of RUVBL1 that is required for homologous recombination repair of TMZ treatment-related DNA damage.
CONCLUSION
Overall, PRMT5 inhibition sensitized GBMNS to TMZ and enhanced TMZ-related DNA damage and cytotoxicity. These findings support further development of this potential therapeutic combination.

Abstract
Glioblastoma is one of the most lethal and treatment-resistant tumors of the central nervous system. Despite maximal surgical and medical therapy, survival remains dismal with a median of 21 months. Despite advances in treatment, this has only led to modest survival benefit. A significant challenge in treatment of glioblastoma is targeting glioma stem cells (GSCs) which are a source of therapy resistance. Oncolytic viral (OV) therapy is a promising therapy for solid tumors that preferentially targets tumor cells for lysis and an anti-tumor immune response while sparing normal cells. Among all OVs, oncolytic Herpes Simplex Virus (oHSV) is substantially ahead in the clinic, with an oHSV T-VEC approved by the FDA for metastatic melanoma treatment and G47∆ which received conditional approval for the treatment of GBM in Japan. In prior work, our group has demonstrated that PTENα expression by an oHSV (HSV-P10) results in improved long-term survivors in intracranial tumor-bearing mice compared to HSVQ treatment. We aim to elucidate the mechanism of improved therapeutic efficacy of HSV-P10 against GBM and evaluate if HSV-P10 may overcome radio-resistance. RNA sequencing and GSEA analysis of primary human GBM cells infected with control HSVQ or HSV-P10 reveals that while HSVQ virus infection leads to an increase in genes regulating IL6-STAT3 pathway, pivotal in maintaining stemness properties, HSV-P10 infection leads to a reduction. HSV-P10 reduces CD133+/CD44+ stem cells, induces DNA damage and sensitizes the GBM cells to irradiation. Our findings reveal a novel mechanism induced by HSV-P10 in combination with irradiation where HSV-P10 modulates IL6-STAT3 signaling downregulating genes associated with stemness (Nestin, Sox2). HSV-P10 infection in combination with irradiation reduces GSC tumor sphere formation in vitro and sensitizes GBMs to radiotherapy in an intracranial mouse xenograft model. Our findings uncover a possible mechanism to overcome GSC-mediated therapy resistance to improve the therapeutic efficacy for GBM.

Abstract
The beta-1 subunit of integrins (CD29) is important for cell-extracellular matrix interactions. CD29 expression is increased in breast cancer cells, and it promotes their invasion, migration, and intravasation, all of which can result in breast cancer brain metastasis (BCBM). While CD29 expression can be correlated to poor prognosis of breast cancer patients, the median survival of BCBM patients predicted to have better prognosis is 36 months. Despite current BCBM treatments such as craniotomy, reaching the metastatic site is often challenging. Modified viral vectors, such as oncolytic herpes simplex virus (oHSV), have been clinically approved for the treatment of malignant melanoma and brain tumors, as they infect and selectively kill tumor cells. Previously, we identified that combination of oHSV and humanized CD29 blocking antibody (OS2966, aCD29) enhanced viral replication by reducing antiviral immune response, increased tumor cell killing, and rendered survival benefit to tumor bearing mice with intra-tumoral, but not systemic, oHSV administration. These findings suggested that the antitumor efficacy of the therapeutic combination required intratumoral delivery of anti-CD29, since the antibody could not penetrate the blood brain barrier and reach intracranial tumors. To overcome this, we report the generation of an oHSV encoding the scFv-Fc fragment of this antibody (HSV-aCD29), which retains its oncolytic function, and evaluate the impact of HSV-aCD29 on the CD29 downstream signaling. We will further characterize the safety, antitumor efficacy, and assess the immune response to HSV-aCD29 in vitro and in vivo. We anticipate that compared to our control virus, HSV-aCD29 will block CD29 activity which will reduce antiviral immune responses and enhance tumor cell lysis, thus improving oHSV efficacy. Together, this study proposes the blockade of CD29 with the targeted delivery of a CD29 blocking antibody mediated by a novel oHSV as a potential synergistic therapy against BCBM.

Abstract
Chemokines such as C-C motif ligand 5 (CCL5) regulate immune cell trafficking in the tumor microenvironment (TME) and govern tumor development, making them promising targets for cancer therapy. However, short half-lives and toxic off-target effects limit their application. Oncolytic viruses (OVs) have become attractive therapeutic agents. Here, we generate an oncolytic herpes simplex virus type 1 (oHSV) expressing a secretable single-chain variable fragment of the epidermal growth factor receptor (EGFR) antibody cetuximab linked to CCL5 by an Fc knob-into-hole strategy that produces heterodimers (OV-Cmab-CCL5). OV-Cmab-CCL5 permits continuous production of CCL5 in the TME, as it is redirected to EGFR+ glioblastoma (GBM) tumor cells. OV-Cmab-CCL5 infection of GBM significantly enhances the migration and activation of natural killer cells, macrophages and T cells; inhibits tumor EGFR signaling; reduces tumor size; and prolongs survival of GBM-bearing mice. Collectively, our data demonstrate that OV-Cmab-CCL5 offers a promising approach to improve OV therapy for solid tumors.

Abstract
Abstract
Tumor suppressive microRNAs (miRNAs) are increasingly implicated in the development of anti-tumor therapy by reprogramming gene network that are aberrantly regulated in cancer cells. This study aimed to pinpoint tumor suppressive miRNAs with therapeutic potential against GBM, one of the most deadly cancers. Whole transcriptome and miRNA expression profiling analyses were performed on human GBM patient tissues. Transient transfection of miRNA mimics was used to investigate the tumor suppressive role of a miRNA (miR-138) in cell proliferation, cell cycle, migration, would healing, and chemosensitivity to temozolomide (TMZ). Orthotopic xenograft mice model using human patient-derived primary GBM cells was used for the survival studies. miR-138 was found as one of the most significantly downregulated miRNAs with an inverse correlation with CD44 expression. Functional studies unveiled that miR-138 negatively regulates the expression of CD44 at protein level by directly binding to the 3’ UTR of CD44. CD44 inhibition by miR-138 overexpression resulted in an inhibition of glioblastoma cell proliferation in vitro through cell cycle arrest as evidenced by a significant induction of p27 and its translocation into nucleus.

Abstract
Abstract
Glioblastoma is an aggressive tumor of the central nervous system associated with a very poor prognosis even with surgery and chemoradiation. We have previously developed an oHSV that encodes for PTENα (HSV-P10) and stimulates anti-tumor immunity. This virus is currently licensed by and is being developed by Mesoblast to evaluate safety and efficacy in patients. To understand the effect of PTENα on tumor cell responses to oHSV therapy we performed RNA sequencing of primary GBM cells infected with control or oHSV-P10. We identified a dysregulation of glycolysis in cells infected with oHSV-P10 relative to control oHSV. Since cancer cells rely heavily on glycolysis for energy production (Warburg effect) the impact of PTENα on metabolic switch was significant. RNA sequencing PCR and western blot analysis showed a significant reduction in cellular Hexokinase II expression and downregulation of HIF-1α in HSV-P10 infected cells. Consistent with the function of HIF1 and hexokinase in driving glycolysis we also observed a significant reduction in glucose uptake and lactate release: implying a reduction in glycolysis in cells after being treated with oHSV-P10. Thus, cellular energetics of HSV-P10 infected cells was directed away from glycolysis relative to HSVQ infected cells. Consistent with this we observed increased, oxidative phosphorylation, production of reactive oxidative species and ATP production. Many cancers, including Glioblastoma are known to utilize the glutamine as a substrate for energy production through its entry into the TCA cycle. Blocking this shows a significant decrease in cell viability and ATP production when combined with HSV-P10. These results indicate that combination of HSV-P10 with radiation has a significant therapeutic potential and should be tested in patients for safety and efficacy.

Abstract
Abstract
GBM, a WHO classified Grade IV glioma, is one of the most lethal and heterogeous primary brain tumors with inevitable recurrence, limiting the median survival time less than 21 months. Current standard-of-care treatment including surgical resection followed by chemo- and radio-therapy remains palliative because of therapy resistance, majorly conferred by GBM stem cells (GSCs), leading to tumor recurrence. With no current effective treatments, novel approaches to overcome GSCs-mediated resistance to chemotherapy and irradiation are urgently required in order to achieve long-term success in GBM therapy. Oncolytic viral (OV) therapy represents a novel and promising biological therapy for solid tumor that preferentially targets tumor cells for lytic destruction, sparing the healthy cells and in the process activating host anti-tumor immune response. Among all OVs, oncolytic Herpes Simplex Virus (oHSV) is substantially ahead in the clinic, with an oHSV T-VEC approved by the FDA for metastatic melanoma treatment. Recently, G47∆, another HSV1 virus, has been granted conditional approval for the treatment of GBM in Japan. Further, several other oHSVs including G207 and HSV1716 are currently being tested for safety and efficacy against GBM. This has fueled great expectations towards OVs as a promising alternative to conventional therapies. Our group has previously shown that PTENα expression by an oHSV (HSV-P10) resulted in further improved long-term survivors in intracranial tumor-bearing mice compared to HSVQ treatment. Here we aim to dissect the molecular mechanisms associated with improved therapeutic efficacy of HSV-P10 against GBM, and if HSV-P10 can overcome GBM cell radioresistance. The RNA sequencing and GSEA analyses of primary human GBM cells infected with control HSVQ or HSV-P10 reveals that while HSVQ virus infection leads to an increase in genes regulating IL6-STAT3 pathway, pivotal in maintaining stemness properties, HSV-P10 infection causes a reduction in the genes regulating this pathway. As a consequence, HSV-P10 reduces CD133+/CD44+ stem cell fraction, induces DNA damage and sensitizes the GBM cells to irradiation. Our findings reveal a novel mechanism induced by HSV-P10 in combination with irradiation whereby HSV-P10 modulates IL6-STAT3 signaling downregulating Sox2, a core transcription factor in the maintenance of GSCs, with a simultaneous decrease in Nestin expression and enhanced GFAP expression promoting GSC differentiation. HSV-P10 infection in combination with irradiation reduces GSC tumor sphere formation in vitro and sensitizes GBMs to radiotherapy in an intracranial mouse xenograft model. Collectively, our findings provide a potential avenue to overcome GSC-mediated therapy resistance to improve the therapeutic efficacy for GBM patients.

Abstract
High-grade gliomas (HGGs) are lethal central nervous system tumors that spread quickly through the brain, making treatment challenging. Integrins are transmembrane receptors that mediate cell-extracellular matrix (ECM) interactions, cellular adhesion, migration, growth, and survival. Their upregulation and inverse correlation in HGG malignancy make targeting integrins a viable therapeutic option. Integrins also play a role in herpes simplex virus 1 (HSV-1) entry. Oncolytic HSV-1 (oHSV) is the most clinically advanced oncolytic virotherapy, showing a superior safety and efficacy profile over standard cancer treatment of solid cancers, including HGG. With the FDA-approval of oHSV for melanoma and the recent conditional approval of oHSV for malignant glioma in Japan, usage of oHSV for HGG has become of great interest. In this review, we provide a systematic overview of the role of integrins in relation to oHSV, with a special focus on its therapeutic potential against HGG. We discuss the pros and cons of targeting integrins during oHSV therapy: while integrins play a pro-therapeutic role by acting as a gateway for oHSV entry, they also mediate the innate antiviral immune responses that hinder oHSV therapeutic efficacy. We further discuss alternative strategies to regulate the dual functionality of integrins in the context of oHSV therapy.

Abstract
Glioblastoma multiforme (GBM) is the most aggressive and fatal disease of all brain tumor types. Most therapies rarely provide clinically meaningful outcomes in the treatment of GBM. Although antibody-drug conjugates (ADCs) are promising anticancer drugs, no ADCs have been clinically successful for GBM, primarily because of poor blood-brain barrier (BBB) penetration. Here, we report that ADC homogeneity and payload loading rate are critical parameters contributing to this discrepancy. Although both homogeneous and heterogeneous conjugates exhibit comparable in vitro potency and pharmacokinetic profiles, the former shows enhanced payload delivery to brain tumors. Our homogeneous ADCs provide improved antitumor effects and survival benefits in orthotopic brain tumor models. We also demonstrate that overly drug-loaded species in heterogeneous conjugates are particularly poor at crossing the BBB, leading to deteriorated overall brain tumor targeting. Our findings indicate the importance of homogeneous conjugation with optimal payload loading in generating effective ADCs for intractable brain tumors. Most therapies rarely provide clinically meaningful improvements in glioblastoma multiforme (GBM) treatment. Anami et al. report that intravenous administration of homogeneous antibody-drug conjugates (ADCs) efficiently delivers payloads to brain tumors, leading to substantially improved tumor growth suppression. Their findings provide rational ADC design for effectively treating intractable brain tumors, including GBM.

Abstract
Rodent brain tumor models have been useful for developing effective therapies for glioblastomas (GBMs). In this review, we first discuss the 3 most commonly used rat brain tumor models, the C6, 9L, and F98 gliomas, which are all induced by repeated injections of nitrosourea to adult rats. The C6 glioma arose in an outbred Wistar rat and its potential to evoke an alloimmune response is a serious limitation. The 9L gliosarcoma arose in a Fischer rat and is strongly immunogenic, which must be taken into consideration when using it for therapy studies. The F98 glioma may be the best of the 3 but it does not fully recapitulate human GBMs because it is weakly immunogenic. Next, we discuss a number of mouse models. The first are human patient-derived xenograft gliomas in immunodeficient mice. These have failed to reproduce the tumor-host interactions and microenvironment of human GBMs. Genetically engineered mouse models recapitulate the molecular alterations of GBMs in an immunocompetent environment and “humanized” mouse models repopulate with human immune cells. While the latter are rarely isogenic, expensive to produce, and challenging to use, they represent an important advance. The advantages and limitations of each of these brain tumor models are discussed. This information will assist investigators in selecting the most appropriate model for the specific focus of their research.

Abstract
BACKGROUND Glioblastoma multiforme (GBM) is the most common high-grade malignant brain tumour in adults and arises from the glial cells in the brain. The prognosis of treated GBM remains very poor with 5-year survival rates of 5%, a figure which has not improved over the last few decades. Currently, there is a modest 14-month overall median survival in patients undergoing maximum safe resection plus adjuvant chemoradiotherapy. HOX gene dysregulation is now a widely recognised feature of many malignancies. METHODS In this study we have focused on HOX gene dysregulation in GBM as a potential therapeutic target in a disease with high unmet need. RESULTS We show significant dysregulation of these developmentally crucial genes and specifically that HOX genes A9, A10, C4 and D9 are strong candidates for biomarkers and treatment targets for GBM and GBM cancer stem cells. We evaluated a next generation therapeutic peptide, HTL-001, capable of targeting HOX gene over-expression in GBM by disrupting the interaction between HOX proteins and their co-factor, PBX. HTL-001 induced both caspase-dependent and -independent apoptosis in GBM cell lines. CONCLUSION In vivo biodistribution studies confirmed that the peptide was able to cross the blood brain barrier. Systemic delivery of HTL-001 resulted in improved control of subcutaneous murine and human xenograft tumours and improved survival in a murine orthotopic model.

Abstract
Despite current progress in treatment, glioblastoma (GBM) remains a lethal primary malignant tumor of the central nervous system. Although immunotherapy has recently achieved remarkable survival effectiveness in multiple malignancies, none of the immune checkpoint inhibitors (ICIs) for GBM have shown anti-tumor efficacy in clinical trials. GBM has a characteristic immunosuppressive tumor microenvironment (TME) that results in the failure of ICIs. Oncolytic herpes simplex virotherapy (oHSV) is the most advanced United States Food and Drug Administration-approved virotherapy for advanced metastatic melanoma patients. Recently, another oHSV, Delytact®, was granted conditional approval in Japan against GBM, highlighting it as a promising treatment. Since oncolytic virotherapy can recruit abundant immune cells and modify the immune TME, oncolytic virotherapy for immunologically cold GBM will be an attractive therapeutic option for GBM. However, as these immune cells have roles in both anti-tumor and anti-viral immunity, fine-tuning of the TME using oncolytic virotherapy will be important to maximize the therapeutic efficacy. In this review, we discuss the current knowledge of oHSV, with a focus on the role of immune cells as friend or foe in oncolytic virotherapy.

Abstract
Cancer is a disease caused by loss of regulatory processes that control cell cycle, resulting in increased proliferation. The loss of control can deregulate both tumor suppressors and oncogenes. Apart from cell intrinsic gene mutations and environmental factors, infection by cancer-causing viruses also induces changes that lead to malignant transformation. This can be caused by both expression of oncogenic viral proteins and also by changes in cellular genes and proteins that affect the epigenome. Thus, these epigenetic modifiers are good therapeutic targets, and several epigenetic inhibitors are approved for the treatment of different cancers. In addition to small molecule drugs, biological therapies such as antibodies and viral therapies are also increasingly being used to treat cancer. An HSV-1 derived oncolytic virus is currently approved by the US FDA and the European Medicines Agency. Similarly, an adenovirus-based therapeutic is approved for use in China for some cancer types. Since viruses can affect cellular epigenetics, the interaction of epigenome-targeting drugs with oncogenic and oncolytic viruses is a highly significant area of investigation. Here we will review the current knowledge about the impact of using epigenetic drugs in tumors positive for oncogenic viruses or as therapeutic combinations with oncolytic viruses.

Abstract
PURPOSE Oncolytic herpes simplex virus-1 (oHSV) infection of brain tumors activates NOTCH, however the consequences of NOTCH on oHSV-induced immunotherapy is largely unknown. Here we evaluated the impact of NOTCH blockade on virus-induced immunotherapy. EXPERIMENTAL DESIGN RNA sequencing (RNA-seq), TCGA data analysis, flow cytometry, Luminex- and ELISA-based assays, brain tumor animal models, and serum analysis of patients with recurrent glioblastoma (GBM) treated with oHSV was used to evaluate the effect of NOTCH signaling on virus-induced immunotherapy. RESULTS TCGA data analysis of patients with grade IV glioma and oHSV treatment of experimental brain tumors in mice showed that NOTCH signaling significantly correlated with a higher myeloid cell infiltration. Immunofluorescence staining and RNA-seq uncovered a significant induction of Jag1 (NOTCH ligand) expression in infiltrating myeloid cells upon oHSV infection. Jag1-expressing macrophages further spread NOTCH activation in the tumor microenvironment (TME). NOTCH-activated macrophages increased the secretion of CCL2, which further amplified myeloid-derived suppressor cells. CCL2 and IL10 induction was also observed in serum of patients with recurrent GBM treated with oHSV (rQnestin34.5; NCT03152318). Pharmacologic blockade of NOTCH signaling rescued the oHSV-induced immunosuppressive TME and activated a CD8-dependent antitumor memory response, resulting in a therapeutic benefit. CONCLUSIONS NOTCH-induced immunosuppressive myeloid cell recruitment limited antitumor immunity. Translationally, these findings support the use of NOTCH inhibition in conjunction with oHSV therapy.

Abstract
Oncolytic herpes simplex virus (oHSV) is a highly promising treatment for solid tumors. Intense research and development efforts have led to first-in-class approval for an oHSV for melanoma, but barriers to this promising therapy still exist that limit efficacy. The process of infection, replication and transmission of oHSV in solid tumors is key to obtaining a good lytic destruction of infected cancer cells to kill tumor cells and release tumor antigens that can prime anti-tumor efficacy. Intracellular tumor cell signaling and tumor stromal cells present multiple barriers that resist oHSV activity. Here, we provide a review focused on oncolytic HSV and the essential viral genes that allow for virus replication and spread in order to gain insight into how manipulation of these pathways can be exploited to potentiate oHSV infection and replication among tumor cells.

Abstract
Abstract
Background
The prognosis of glioblastoma (GBM) remains dismal because therapeutic approaches have limited effectiveness. A new targeted treatment using MEK inhibitors, including trametinib, has been proposed to improve GBM therapy. Trametinib had a promising preclinical effect against several cancers, but its adaptive treatment resistance precluded its clinical translation in GBM. Previously, we have demonstrated that protein arginine methyltransferase 5 (PRMT5) is upregulated in GBM and its inhibition promotes apoptosis and senescence in differentiated and stem-like tumor cells, respectively. We tested whether inhibition of PRMT5 can enhance the efficacy of trametinib against GBM.
Methods
Patient-derived primary GBM neurospheres (GBMNS) with transient PRMT5 knockdown were treated with trametinib and cell viability, proliferation, cell cycle progression, ELISA, and western blot were analyzed. In vivo, NSG mice were intracranially implanted with PRMT5-intact and -depleted GBMNS, treated with trametinib by daily oral gavage, and observed for tumor progression and mice survival rate.
Results
PRMT5 depletion enhanced trametinib-induced cytotoxicity in GBMNS. PRMT5 knockdown significantly decreased trametinib-induced AKT and ERBB3 escape pathways. However, ERBB3 inhibition alone failed to block trametinib-induced AKT activity suggesting that the enhanced antitumor effect imparted by PRMT5 knockdown in trametinib-treated GBMNS resulted from AKT inhibition and not ERBB3 inhibition. In orthotopic murine xenograft models, PRMT5-depletion extended the survival of tumor-bearing mice, and combination with trametinib further increased survival.
Conclusion
Combined PRMT5/MEK inhibition synergistically inhibited GBM in animal models and is a promising strategy for GBM therapy.

Abstract
Abstract
Oncolytic herpes simplex virus-1 (oHSV) is novel FDA-approved immunotherapy for advanced melanoma patients in US. Also, oHSV is recently approved for the treatment of recurrent GBM in Japan. We have shown that oHSV treatment of GBM cells induces NICD cleavage and NOTCH activation in adjacent uninfected glioma cells via HSV-1 microRNA-H16 (Otani Y and Yoo JY, Clin Cancer Res, 2020), however, the consequences of NOTCH on immunotherapy in GBM is unknow. Here we have investigated the impact of oHSV-induced NOTCH signaling on the tumor microenvironment (TME). Analysis of TCGA GBM data and experimental murine models revealed NOTCH induced immunosuppressive myeloid cell recruitment and limited anti-tumor immunity. In oHSV treated tissue, viral infection educated tumor associated macrophages to secrete CCL2 which recruited monocytic myeloid derived suppressor cell (MDSC) that attenuated anti-tumor immunity. Consistent with this, CCL2 induction was also observed in serum of recurrent GBM patients treated with oHSV (NCT03152318). Importantly, blockade of NOTCH signaling reduced the oHSV induced immunosuppressive environment and activated a CD8 dependent anti-tumor memory response. These findings present the opportunities for combination therapies that can help improve therapeutic benefit and anti-tumor immunity in GBM.

Abstract
With limited effective therapeutic strategies, the prognosis for glioblastoma (GBM) is very poor. Our previous study shows that the expression of Protein Arginine Methyltransferase 5 (PRMT5) is upregulated in GBM; its inhibition promotes apoptosis and senescence in differentiated and stem-like tumor cells, respectively. MEK inhibitors, including trametinib, are currently under investigation for GBM therapy. In this study, we tested whether inhibition of PRMT5 can enhance the anti-GBM efficacy of trametinib. Patient-derived primary GBM neurospheres (GBMNS) with transient PRMT5 knockdown were treated with trametinib and cell viability, proliferation, cell cycle progression, ELISA, and western blot analysis were conducted. In vivo, PRMT5-intact and -depleted GBMNS were intracranially implanted in NSG mice and treated with trametinib by daily oral gavage, and tumor progression and mice survival rate were analyzed by MRI and Kaplan-Meier survival curve, respectively. Depletion of PRMT5 increased the cytotoxic effect of trametinib in GBMNS. Trametinib treatment increased the activity of ERBB3 and AKT; With PRMT5 knockdown, the activity of both AKT and ERBB3 decreased significantly. But, inhibition of ERBB3 alone failed to block the trametinib-induced AKT activity suggesting that even though PRMT5 regulates the activity of both ERBB3 and AKT, the enhanced antitumor effect imparted by PRMT5 knockdown in trametinib treated GBMNS is because of AKT inhibition alone. In vivo, PRMT5-depletion extended the survival of the tumor-bearing mice that further increased in combination with trametinib treatment. Interestingly, trametinib treatment alone had no survival benefit.

Abstract
Purpose: Monoclonal antibodies (mAbs) blocking immune checkpoints have emerged as important cancer therapeutics, as exemplified by systemic administration of the IgG1 anti-CD47 mAb that blocks the "don't eat me" pathway. However, this strategy is associated with severe toxicity. Experimental Design: To improve therapeutic efficacy while reducing toxicities for ovarian cancer, we engineered an oncolytic herpesvirus (oHSV) to express a full-length, soluble anti-CD47 mAb with a human IgG1 scaffold (OV-αCD47-G1) or IgG4 scaffold (OV-αCD47-G1). Results: Both IgG1 and IgG4 anti-CD47 mAbs secreted by oHSV-infected tumor cells blocked the CD47-SIRPα signal pathway, enhancing macrophage phagocytosis against ovarian tumor cells. OV-αCD47-G1, but not OV-αCD47-G4, activated human NK cell cytotoxicity and macrophage phagocytosis by binding to the Fc receptors of these cells. In vivo, these multifaceted functions of OV-αCD47-G1 improved mouse survival in xenograft and immunocompetent mouse models of ovarian cancer when compared to OV-αCD47-G4 and a parental oHSV. The murine counterpart of OV-αCD47-G1, OV-αmCD47-G2b, also enhanced mouse NK cell cytotoxicity and macrophage phagocytosis and prolonged survival of mice bearing ovarian tumors compared to OV-αmCD47-G3. OV-αmCD47-G2b was also superior to αmCD47-G2b and showed a significantly better effect when combined with an antibody against PD-L1 that was upregulated by oHSV infection. Conclusion: Our data demonstrate that an oHSV encoding a full-length human IgG1 anti-CD47 mAb, when used as a single agent or combined with another agent, is a promising approach for improving ovarian cancer treatment via enhancing innate immunity, as well as performing its known oncolytic function and modulation of immune cells.

Abstract
Oncolytic herpes simplex virus-1 is capable of lysing tumor cells while alerting the immune system. CD47, in collaboration with SIRPα, represents an important immune checkpoint to inhibit phagocytosis by innate immune cells. Here we show locoregional control of glioblastoma by an oncolytic herpes virus expressing a full-length anti(α)-human CD47 IgG1 or IgG4 antibody. The antibodies secreted by the virus-infected glioblastoma cells block the CD47 'don't eat me' signal irrespective of the subclass; however, αCD47-IgG1 has a stronger tumor killing effect than αCD47-IgG4 due to additional antibody-dependent cellular phagocytosis by macrophages and antibody-dependent cellular cytotoxicity by NK cells. Intracranially injected αCD47-IgG1-producing virus continuously releases the respective antibody in the tumor microenvironment but not into systemic circulation; additionally, αCD47-IgG1-producing virus also improves the survival of tumor-bearing mice better than control oncolytic herpes virus combined with topical αCD47-IgG1. Results from immunocompetent mouse tumor models further confirm that macrophages, and to a lesser extent NK cells, mediate the anti-tumor cytotoxicity of antibody-producing oncolytic herpesviruses. Collectively, oncolytic herpes simplex virus-1 encoding full-length antibodies could improve immune-virotherapy for glioblastoma.

Abstract
Prolonged inorganic arsenic (iAs) exposure is widely associated with brain damage particularly in the hippocampus via oxidative and apoptotic pathways. Resveratrol (RES) has gained considerable attention because of its benefits to human health. However, its neuroprotective potential against iAs-induced toxicity in CA1 region of hippocampus remains unexplored. Therefore, we investigated the neuroprotective efficacy of RES against arsenic trioxide (As2O3)-induced adverse effects on neuronal morphology, apoptotic markers and oxidative stress parameters in mouse CA1 region (hippocampus). Adult female Swiss albino mice of reproductive maturity were orally exposed to either As2O3 (2 and 4 mg/kg bw) alone or in combination with RES (40 mg/kg bw) for a period of 45 days. After animal sacrifice on day 46, the perfusion fixed brain samples were used for the observation of neuronal morphology and studying the morphometric features. While the freshly dissected hippocampi were processed for biochemical estimation of oxidative stress markers and western blotting of apoptosis-associated proteins. Chronic iAs exposure led to significant decrease in Stratum Pyramidale layer thickness along with reduction in cell density and area of Pyramidal neurons in contrast to the controls. Biochemical analysis showed reduced hippocampal GSH content but no change in total nitrite (NO) levels following iAs exposure. Western blotting showed apparent changes in the expression levels of Bax and Bcl-2 proteins following iAs exposure, however the change was statistically insignificant. Contrastingly, iAs +RES co-treatment exhibited substantial reversal in morphological and biochemical observations. Together, these findings provide preliminary evidence of neuroprotective role of RES on structural and biochemical alterations pertaining to mouse hippocampus following chronic iAs exposure.

Abstract
Glioblastoma (GBM) is one of the most deadly cancers and poorly responses to chemotherapies, such as temozolomide (TMZ). Dysregulation of intrinsic signaling pathways in cancer cells are often resulted by dysregulated tumor suppressive microRNAs (miRNAs). Previously, we found miR-138 as one of tumor suppressive miRNAs that were significantly down-regulated in GBM. In this study, we demonstrated that ectopic over-expression of miR-138 sensitizes GBM cells to the treatment of TMZ and increased apoptotic cell death. Mechanistically, miR-138 directly repressed the expression of Survivin, an anti-apoptotic protein, to enhance caspase-induced apoptosis upon TMZ treatment. Using an intracranial GBM xenograft mice model, we also showed that combination of miR-138 with TMZ increases survival rates of the mice compared to the control mice treated with TMZ alone. This study provides strong preclinical evidence of the therapeutic benefit from restoration of miR-138 to sensitize the GBM tumor to conventional chemotherapy.

Abstract
Placental site trophoblastic tumor can be resistant to chemotherapy. Multidisciplinary care is required for management of advanced disease. Increased PD-L1 expression can help guide use of immunotherapies. Complete responses are possible with aggressive multidisciplinary management.
Placental Site Trophoblastic Tumor (PSTT) is a rare malignancy that often presents with extensive disease and can be resistant to traditional treatments. We present the case of a woman with stage IV PSTT who was initially managed with neoadjuvant chemotherapy followed by tumor debulking. Adjuvant therapy was guided by further pathologic analysis that revealed high levels of staining for PD-L1 as well as the presence of tumor infiltrating lymphocytes (TILs). Subsequently, the patient was treated with traditional chemotherapy with the EP/EMA regimen with the addition of pembrolizumab. The patient’s treatment course was complicated by the development of pulmonary arteriovenous malformations, autoimmune thyroiditis thought to be secondary to immunotherapy, and significant tinnitus secondary to platinum agents. Currently the patient is in follow up and remains in a complete remission.

Abstract
OBJECTIVE To compare the safety and efficacy of 10% sinecatechins (Veregen® ) ointment against placebo in the treatment of usual type vulvar intraepithelial neoplasia (uVIN). DESIGN A Phase II double-blind randomised control trial. SETTING A tertiary gynaecological oncology referral centre. POPULATION All women diagnosed with primary and recurrent uVIN. METHODS Eligible patients were randomised 1:1 to receive either sinecatechins or placebo ointment (applied three times daily for 16 weeks) and were followed up at 2, 4, 8, 16, 32 and 52 weeks. MAIN OUTCOME MEASURES The primary outcome measure, recorded at 16 and 32 weeks, was histological response (HR). Secondary outcome measures included clinical (CR) response, toxicity, quality of life and pain scores. RESULTS There was no observed difference in HR between the two arms. However, of the 26 patients who were randomised, all 13 patients who received sinecatechins showed either complete (n = 5) or partial (n = 8) CR, when best CR was evaluated. In placebo group, three patients had complete CR, two had partial CR, six had stable disease and two were lost to follow up. Patients in the sinecatechins group showed a statistically significant improvement in best observed CR as compared with the placebo group (P = 0.002). There was no difference in toxicity reported in either group. CONCLUSION Although we did not observe a difference in HR between the two treatment arms, we found that 10% sinecatechins application is safe and shows promise in inducing clinical resolution of uVIN lesions and symptom improvement, thus warranting further investigation in a larger multicentre study. TWEETABLE ABSTRACT A randomised control study indicating that sinecatechins ointment may be a novel treatment for uVIN.

Abstract
Tumor suppressive microRNAs (miRNAs) are increasingly implicated in the development of anti-tumor therapy by reprogramming gene network that are aberrantly regulated in cancer cells. This study aimed to determine the therapeutic potential of putative tumor suppressive miRNA, miR-138, against glioblastoma (GBM). Whole transcriptome and miRNA expression profiling analyses on human GBM patient tissues identified miR-138 as one of the significantly downregulated miRNAs with an inverse correlation with CD44 expression. Transient overexpression of miR-138 in GBM cells inhibited cell proliferation, cell cycle, migration, and wound healing capability. We unveiled that miR-138 negatively regulates the expression of CD44 by directly binding to the 3' UTR of CD44. CD44 inhibition by miR-138 resulted in an inhibition of glioblastoma cell proliferation in vitro through cell cycle arrest as evidenced by a significant induction of p27 and its translocation into nucleus. Ectopic expression of miR-138 also increased survival rates in mice that had an intracranial xenograft tumor derived from human patient-derived primary GBM cells. In conclusion, we demonstrated a therapeutic potential of tumor suppressive miR-138 through direct downregulation of CD44 for the treatment of primary GBM.

Abstract
Background A human chorionic gonadotropin (hCG) cut-off of ≤300 IU/l for starting actinomycin D (ActD) in post-molar gestational trophoblastic neoplasia (GTN) patients developing methotrexate resistance (MTX-R) reduced the number of women needing toxic multi-agent chemotherapy (etoposide, MTX and ActD alternating weekly with cyclophosphamide and vincristine; EMA/CO) without affecting survival. Here we assess whether an increased hCG cut-off of ≤1000 IU/l spares more women EMA/CO. Patients and methods All post-molar GTN patients treated with first-line methotrexate and folinic acid (MTX/FA) were identified in a national cohort between 2009 and 2016. Data collected included age, FIGO score, the hCG levels at MTX-R, and treatment outcomes. Results In total, 609 GTN patients commenced treatment with MTX/FA achieving a complete response in 57% (348/609). Resistance developed in 25.1% (153/609) at an hCG ≤ 1000 IU/l and switching to ActD achieved remission in 92.8% without any major toxicity with the remaining 7.2% remitting on EMA/CO. Comparative analysis of patients switching at an hCG <100 versus 100-300 versus 300-1000 IU/l revealed a significant fall in the cure rate with second-line ActD from 97% (93/96) to 87% (34/39) to 78% (14/18), respectively, P = 0.009. However, by increasing the hCG cut-off from ≤300 to ≤1000 IU/l, 14 patients were spared EMA/CO chemotherapy. Moreover, in the present series, all post-molar GTN remain in remission. Conclusion This study demonstrates that increasing the hCG cut-off from ≤300 to ≤1000 IU/l for choosing patients for ActD following MTX-R spares more women with GTN from the greater toxicity of EMA/CO without compromising 100% survival outcomes. An hCG cut-off of ≤1000 IU/l for ActD over EMA/CO treatment in MTX-R GTN spares women toxicity without affecting survival. On developing MTX-R, as the hCG cut-off for selecting ActD versus EMA/CO rises, the complete response rate for ActD falls. Half of FIGO-7 patients were cured on single-agent treatment (MTX/FA or sequential ActD), warranting further investigation.

Abstract
OBJECTIVE Brain arteriovenous malformations (bAVMs) are a leading cause of hemorrhagic stroke and neurological deficits in children and young adults, however, no pharmacological intervention is available to treat these patients. Although more than 95% of bAVMs are sporadic without family history, the pathogenesis of sporadic bAVMs is largely unknown, which may account for the lack of therapeutic options. KRAS mutations are frequently observed in cancer, and a recent unprecedented finding of these mutations in human sporadic bAVMs offers a new direction in the bAVM research. Using a novel adeno-associated virus targeting brain endothelium (AAV-BR1), the current study tested if endothelial KRASG12V mutation induces sporadic bAVMs in mice. METHODS Five-week-old mice were systemically injected with either AAV-BR1-GFP or -KRASG12V . At 8 weeks after the AAV injection, bAVM formation and characteristics were addressed by histological and molecular analyses. The effect of MEK/ERK inhibition on KRASG12V -induced bAVMs was determined by treatment of trametinib, a US Food and Drug Administration (FDA)-approved MEK/ERK inhibitor. RESULTS The viral-mediated KRASG12V overexpression induced bAVMs, which were composed of a tangled nidus mirroring the distinctive morphology of human bAVMs. The bAVMs were accompanied by focal angiogenesis, intracerebral hemorrhages, altered vascular constituents, neuroinflammation, and impaired sensory/cognitive/motor functions. Finally, we confirmed that bAVM growth was inhibited by trametinib treatment. INTERPRETATION Our innovative approach using AAV-BR1 confirms that KRAS mutations promote bAVM development via the MEK/ERK pathway, and provides a novel preclinical mouse model of bAVMs which will be useful to develop a therapeutic strategy for patients with bAVM.

Abstract
Because most patients with multiple myeloma (MM) develop resistance to current regimens, novel approaches are needed. Genetically modified, replication-competent oncolytic viruses exhibit high tropism for tumor cells regardless of cancer stage and prior treatment. Receptors of oncolytic herpes simplex virus 1 (oHSV-1), NECTIN-1, and HVEM are expressed on MM cells, prompting us to investigate the use of oHSV-1 against MM. Using oHSV-1-expressing GFP, we found a dose-dependent increase in the GFP+ signal in MM cell lines and primary MM cells. Whereas NECTIN-1 expression is variable among MM cells, we discovered that HVEM is ubiquitously and highly expressed on all samples tested. Expression of HVEM was consistently higher on CD138+/CD38+ plasma cells than in non-plasma cells. HVEM blocking demonstrated the requirement of this receptor for infection. However, we observed that, although oHSV-1 could efficiently infect and kill all MM cell lines tested, no viral replication occurred. Instead, we identified that oHSV-1 induced MM cell apoptosis via caspase-3 cleavage. We further noted that oHSV-1 yielded a significant decrease in tumor volume in two mouse xenograft models. Therefore, oHSV-1 warrants exploration as a novel potentially effective treatment option in MM, and HVEM should be investigated as a possible therapeutic target.

Abstract
BACKGROUND Despite multi-model therapy of maximal surgical resection, radiation, chemotherapy, and tumor treating fields, the median survival of Glioblastoma (GBM) patients is less than 15 months. Protein Arginine Methyltransferase 5 (PRMT5) catalyzes the symmetric di-methylation of arginine residues and is overexpressed in GBM. Inhibition of PRMT5 causes senescence in stem-like GBM tumor cells. LB100, a first-in-class small molecular inhibitor of Protein Phosphatase 2A (PP2A) can sensitize therapy-resistant tumor cells. Here, we tested the anti-GBM effect of concurrent PRMT5 and PP2A inhibition. METHODS Patient-derived primary GBM neurospheres (GBMNS), transfected with PRMT5 target-specific siRNA were treated with LB100 and subjected to in vitro assays including PP2A activity and western blot. The intracranial mouse xenograft model was used to test the in vivo antitumor efficacy of combination treatment. RESULTS We found that PRMT5-depletion increased PP2A activity in GBMNS. LB100 treatment significantly reduced the viability of PRMT5-depleted GBMNS compared to PRMT5 intact GBMNS. LB100 enhanced G1 cell cycle arrest induced by PRMT5-depletion. Combination therapy also increased the expression of phospho-MLKL. Necrostatin-1 rescued PRMT5-depleted cells from the cytotoxic effects of LB100, indicating that necroptosis caused the enhanced cytotoxicity of combination therapy. In the in vivo mouse tumor xenograft model, LB100 treatment combined with transient depletion of PRMT5 significantly decreased tumor size and prolonged survival, while LB100 treatment alone had no survival benefit. CONCLUSION Overall, combined PRMT5 and PP2A inhibition had significantly greater antitumor effects than PRMT5 inhibition alone.

Abstract
PURPOSE Here we investigated the impact of oncolytic herpes simplex virus (HSV) treatment on cisplatin sensitivity of platinum-resistant ovarian cancer, and the impact of the combination on immunotherapy. EXPERIMENTAL DESIGN Therapeutic efficacy of the combination was assessed in platinum-resistant human and murine ovarian cancer peritoneal metastatic mouse models (n = 9-10/group). RNA sequencing along with flow cytometry of splenocytes from treated mice was employed to examine the effect of antitumor immune response (n = 3/group). Anti-PD-1 antibody was performed to evaluate impact on checkpoint inhibition in vivo. RESULTS Gene Ontology pathway analysis uncovered disruption of cellular extracellular vesicle (EV)-related pathways in infected cells (FDR = 2.97E-57). Mechanistically, we identified reduced expression of transporters expressed on EV implicated in cisplatin efflux. The increased cisplatin retention led to increased cisplatin-DNA adducts, which resulted in micronuclei and the subsequent activation of cGAS-STING pathway with a significant activation of innate immune cells and translated to an increase in antitumor immunity and efficacy. In mice bearing platinum-resistant ovarian cancer, we also observed a feedback induction of PD-L1 on tumor cells, which sensitized combination-treated mice to anti-PD-1 immune checkpoint therapy. CONCLUSIONS To our knowledge, this is the first report to show HSV-induced cisplatin retention in infected cells. The consequential increased damaged DNA was then expelled from cells as micronuclei which resulted in induction of inflammatory responses and education of antitumor immunity. The combination therapy also created an environment that sensitized tumors to immune checkpoint therapy.

Abstract
The gut microbiome is fundamental in neurogenesis processes. Alterations in microbial constituents promote inflammation and immunosuppression. Recently, in immune-oncology, specific microbial taxa have been described to enhance the effects of therapeutic modalities. However, the effects of microbial dysbiosis on glioma are still unknown. The aim of this study was to explore the effects of glioma development and Temozolomide (TMZ) on fecal microbiome in mice and humans. C57BL/6 mice were implanted with GL261/Sham and given TMZ/Saline. Fecal samples were collected longitudinally and analyzed by 16S rRNA sequencing. Fecal samples were collected from healthy controls as well as glioma patients at diagnosis, before and after chemoradiation. Compared to healthy controls, mice and glioma patients demonstrated significant differences in beta diversity, Firmicutes/Bacteroides (F/B) ratio, and increase of Verrucomicrobia phylum and Akkermansia genus. These changes were not observed following TMZ in mice. TMZ treatment in the non-tumor bearing mouse-model diminished the F/B ratio, increase Muribaculaceae family and decrease Ruminococcaceae family. Nevertheless, there were no changes in Verrucomicrobia/Akkermansia. Glioma development leads to gut dysbiosis in a mouse-model, which was not observed in the setting of TMZ. These findings seem translational to humans and warrant further study.

Abstract
Abstract
NOTCH signaling is a method of cell-cell communication where membrane bound NOTCH ligands on signal-sending cells can bind to and initiate cleavage of the NOTCH receptor, releasing NICD which can initiate signal transduction in adjacent “signal-receiving” cells. We have recently shown that oHSV treatment of GBM cells induces NICD cleavage and NOTCH activation in adjacent uninfected glioma cells. RNA sequencing of GBM cells post-infection also uncovered Gene Ontology NOTCH signaling pathway to be significantly upregulated. This activation was induced by viral miRNA-H16, which represses FIH-1 expression. FIH-1 was found to be a negative regulator of Mib1, a ubiquitin ligase, which activates NOTCH ligand-mediated activation of adjacent signal-receiving cells bearing the NOTCH receptor (Otani et al Clin. Can. Res. 2020). Here we have investigated the impact of oHSV-induced NOTCH signaling on the tumor microenvironment. Treatment of brain tumors in immune competent mice with oHSV and NOTCH blocking gamma secretase inhibitor (GSI) induced an anti-tumor memory immune response. Long term survivors in mice treated with the combination also completely rejected subsequent tumor re-challenge in the other hemisphere. UMAP of flow cytometry of tumor-bearing hemispheres and functional analysis of isolated cellular fractions from treated mice showed a significant influx of MDSC cells after oHSV treatment that was rescued in mice treated with oHSV and GSI. Ongoing mechanistic studies are uncovering a significant induction of NOTCH in tumor associated macrophages that aids in recruitment of MDSC cells. Overall these studies have uncovered a significant impact of oHSV therapy on GBM tumor microenvironment and presents opportunities for combination therapies that can help improve therapeutic benefit and anti-tumor immunity.

Abstract
Abstract
BACKGROUND: Despite multi-model therapy of maximal surgical resection, radiation, chemotherapy, and tumor treating fields, median survival of Glioblastoma (GBM) patients is less than two years. Protein Arginine Methyltransferase 5 (PRMT5) catalyzes the symmetric di-methylation of arginine residues and is overexpressed in GBM. Inhibition of PRMT5 causes senescence of immature GBM tumor cells. LB100, first-in-class small molecule inhibitor of Protein Phosphatase 2A (PP2A) can sensitize therapy-resistant tumor cells. Here, we tested the anti-GBM effect of concurrent PRMT5 and PP2A inhibition. Methods: Patient-derived primary GBM neurospheres (GBMNS), transfected with PRMT5 target-specific siRNA were treated with LB100 and subjected to in vitro assays including PP2A activity and western blot. The intracranial mouse xenograft model was used to test the in vivo antitumor efficacy of combination treatment. Results: We found that PRMT5-depletion increased PP2A activity in GBMNS. LB100 treatment significantly reduced the viability of PRMT5-depleted GBMNS compared to PRMT5 intact GBMNS. LB100 enhanced the G1 cell cycle arrest induced by PRMT5-depletion. Combination therapy also increased the expression of phospho-MLKL. Necrostatin-1 rescued PRMT5-depleted cells from the cytotoxic effects of LB100, indicating that necroptosis caused the enhanced cytotoxicity of combination therapy. In the in vivo mouse tumor xenograft model, LB100 treatment combined with transient depletion of PRMT5 significantly decreased tumor size and prolonged mice survival, while LB100 treatment alone had no survival benefit. Conclusion: Overall, combined PRMT5 and PP2A inhibition had significantly greater antitumor effects than PRMT5 inhibition alone.

Abstract
Abstract
INTRODUCTION
Glioblastoma (GBM) is the most common malignant primary brain tumor. With limited effective therapeutic strategies, prognosis for GBM is very poor. Our previous study shows that the expression of Protein Arginine Methyltransferase 5 (PRMT5) is upregulated in GBM; its inhibition promotes anti-GBM effect through apoptosis and senescence of mature and immature tumor cells, respectively. In GBM, RAS-RAF- MEK-ERK signaling is aberrantly activated and promotes tumor growth. Therefore, MEK inhibitors, including trametinib are currently under investigation for GBM therapy. In this study, we tested whether inhibition of PRMT5 can enhance the anti-tumor efficacy of trametinib in GBM.
METHODS
Patient-derived primary GBM neurospheres (GBMNS) with transient PRMT5 knockdown were treated with trametinib and cell viability, proliferation, cell cycle progression, and western blot analysis were conducted. In vivo, PRMT5-intact and -depleted GBMNS were intracranially implanted in NSG mice and treated with trametinib by daily oral gavage, and tumor progression and mice survival rate were analyzed by MRI and Kaplan-Meier survival curve, respectively.
RESULTS
Trametinib treatment upregulated the expression of PRMT5 in GBMNS. Depletion of PRMT5 increased the cytotoxic effect of trametinib in GBMNS. In concurrence with the trametinib-induced PRMT5 upregulation, trametinib treatment increased the activity of AKT that was blocked with PRMT5 knockdown. In vivo, PRMT5-depletion extended the survival of the tumor bearing mice that further increased in combination with trametinib treatment. Interestingly, trametinib treatment alone had no survival benefit.
CONCLUSION
Trametinib treatment induces PRMT5 expression. Depletion of trametinib-induced PRMT5 expression sensitizes GBMNS for trametinib by inhibiting AKT activity.
