Abstract
Unresectable recurrent lymph node metastasis of colorectal cancer (CRC) is considered as an incurable disease clinically and has a very poor prognosis. Here, we report a male KRAS wild-type CRC case with a huge abdominal lymph node metastasis (12 cm in diameter) after CRC surgery. After three intratumoral injections of oncolytic virus (H101) combined with four cycles of low-dose oral capecitabine, the size of the metastatic lymph node shrank remarkably in response to the anticancer drug and a complete response (CR) was achieved with progression-free survival (PFS) of 19 months. The main adverse reaction was mild fever, which was relieved after physical cooling. The patient is in a general good condition now without any relapse of abdominal lymph node for over a year. On this basis, we propose that the combination therapy of oncolytic virus and capecitabine could be a promising clinical therapeutic strategy for unresectable recurrent lymph node metastasis in CRC patients.

Abstract
Human Adenoviruses (HAdV) are nearly ubiquitous pathogens comprising numerous sub-types that infect various tissues and organs. Among many encoded proteins that facilitate viral replication and subversion of host cellular processes, the viral E4orf1 protein has emerged as an intriguing yet under-investigated player in the complex interplay between the virus and its host. E4orf1 has gained attention as a metabolism activator and oncogenic agent, while recent research is showing that E4orf1 may play a more important role in modulating cellular pathways such as PI3K-Akt-mTOR, Ras, the immune response and further HAdV replication stages than previously anticipated. In this review, we aim to explore the structure, molecular mechanisms, and biological functions of E4orf1, shedding light on its potentially multifaceted roles during HAdV infection, including metabolic diseases and oncogenesis. Furthermore, we discuss the role of functional E4orf1 in biotechnological applications such as Adenovirus (AdV) vaccine vectors and oncolytic AdV. By dissecting the intricate relationships between HAdV types and E4orf1 proteins, this review provides valuable insights into viral pathogenesis and points to promising areas of future research.

Abstract
Oncolytic virus (OV) therapy has emerged as a promising frontier in cancer treatment, especially for solid tumours. While immunotherapies like immune checkpoint inhibitors and CAR-T cells have demonstrated impressive results, their limitations in inducing complete tumour regression have spurred researchers to explore new approaches targeting tumours resistant to current immunotherapies. OVs, both natural and genetically engineered, selectively replicate within cancer cells, inducing their lysis while sparing normal tissues. Recent advancements in clinical research and genetic engineering have enabled the development of targeted viruses that modify the tumour microenvironment, triggering anti-tumour immune responses and exhibiting synergistic effects with other cancer therapies. Several OVs have been studied for breast cancer treatment, including adenovirus, protoparvovirus, vaccinia virus, reovirus, and herpes simplex virus type I (HSV-1). These viruses have been modified or engineered to enhance their tumour-selective replication, reduce toxicity, and improve oncolytic properties.Newer generations of OVs, such as Oncoviron and Delta-24-RGD adenovirus, exhibit heightened replication selectivity and enhanced anticancer effects, particularly in breast cancer models. Clinical trials have explored the efficacy and safety of various OVs in treating different cancers, including melanoma, nasopharyngeal carcinoma, head and neck cancer, and gynecologic malignancies. Notably, Talimogene laherparepvec (T-VEC) and Oncorine have. been approved for advanced melanoma and nasopharyngeal carcinoma, respectively. However, adverse effects have been reported in some cases, including flu-like symptoms and rare instances of severe complications such as fistula formation. Although no OV has been approved specifically for breast cancer treatment, ongoing preclinical clinical trials focus on four groups of viruses. While mild adverse effects like low-grade fever and nausea have been observed, the effectiveness of OV monotherapy in breast cancer remains insufficient. Combination strategies integrating OVs with chemotherapy, radiotherapy, or immunotherapy, show promise in improving therapeutic outcomes. Oncolytic virus therapy holds substantial potential in breast cancer treatment, demonstrating safety in trials. Multi-approach strategies combining OVs with conventional therapies exhibit more promising therapeutic effects than monotherapy, signalling a hopeful future for OV-based breast cancer treatments.

Drug Des Devel Ther 2023; 17:3507-3522. [PMID: 38046281 PMCID: PMC10691960 DOI: 10.2147/dddt.s429180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 11/07/2023] [Indexed: 12/05/2023] Open
Abstract
Objective Genomic profiles relating to H101 treatment-induced alterations are yet to be achieved. Here, we evaluated the impact of H101 via exome-sequencing approaches aiming to probe for potential biomarkers that are actionable in the treatment of persistent/recurrent/metastatic (P/R/M) cervical cancer. Methods Whole exome sequencing (WES) was performd on paired pre- and post-H101 samples from 17 P/R/M cervical cancer patients who received serial intra-tumor injections of H101. Somatic mutations, including high-frequency mutations, microsatellite instability (MSI) status, tumor mutation burden (TMB), clonal evolution, and mutational signature were analyzed. Results The median follow-up time after the H101 treatment was 14 months. Complete response was achieved in 9 patients, 3 patients achieved partial response, and 2 patients had stable disease, resulting in an objective response rate (ORR) of 70.6% (95% CI: 46.4%-96.7%). WES analysis showed no difference in treatment-related mutation characteristics, including non-synonymous-SNVs and TMB status. Patients with lower TMB were correlated with improved H101 response rates (P=0.044), whereas the same was not evident in high MSI (MSI-H) versus non-MSI-H patients (P=0.528). We observed a few high-frequency mutation genes (TTN, KMT2D, ALDOA, DNAH7, ADAP1, PTPN23, and THEMIS2) that probably carry functional importance in response to H101 treatment, among which KMT2D and ADAP1 mutations were associated with inferior progression-free survival (PFS) and/or overall survival (OS) (P<0.05). Notably, H101 treatment-induced accumulating subclones or clusters in primary tumors and some (Signature 2) were associated with shorter PFS. Conclusion We conducted an unprecedented work via a WES-based approach and provided preliminary insights into H101 treatment-induced genetic aberrations in which some genes (TTN, KMT2D, ALDOA, DNAH7, ADAP1, PTPN23, and THEMIS2) could be considered potential therapeutic targets of H101-containing treatment in cervical carcinoma. Moreover, the therapy-associated characteristics such as clonal evolution and a mutational signature may warrant further evaluation of H101 in clinical settings for treating cervical carcinoma.

Abstract
BACKGROUND The aim of this study was to analyze the effectiveness and safety of H101 in Chinese patients with malignant pleural effusion and ascites (MPE/MA) in the real world. METHODS This multicenter, observational, real-world study recruited patients with MPE/MA caused by malignant tumor receiving H101-containing treatment between January 2020 and June 2022. Effectiveness was evaluated by overall remission rate (ORR), and safety was evaluated based on adverse events (AEs). Subgroup analysis was performed on patients grouped according to tumor type, the volume of MPE and MA, and dosage of H101. RESULTS A total of 643 eligible patients were enrolled, and 467 received H101 monotherapy and 176 received H101 combined with chemotherapy. The ORR of total patients was60.3% with 388 case of PR. In the H101 monotherapy group, the decrease of MPE or MA was achieved in 282 (60.4%, PR) patients, 176 (37.7%, NC) patients showed no change in volume of MPE or MA, and nine (1.9%, PD) patients showed an increase, yielding an ORR of 60.4% (282/467). The ORR for the combination therapy group was 60.2% (106/176), with 106 cases of PR, 69 cases of NC and one case of PD. Subgroup analyses based on tumor type, volume of MPE and MA, and dosage of H101 all showed high ORR, approximately 60%. The main AEs associated with H101-containing regimens were fever, nausea and vomiting. No serious AEs occurred in both groups. CONCLUSION Encouraging clinical benefits and manageable toxicity of H101 against MPE/MA were preliminarily observed in the real-world clinical setting, indicating that the H101-containing regimen is reliable, safe, and feasible, providing a novel and effective option for the treatment of this disease.

Abstract
The consequences of human adenovirus (HAdV) infections are generally mild. However, despite the perception that HAdVs are harmless, infections can cause severe disease in certain individuals, including newborns, the immunocompromised, and those with pre-existing conditions, including respiratory or cardiac disease. In addition, HAdV outbreaks remain relatively common events and the recent emergence of more pathogenic genomic variants of various genotypes has been well documented. Coupled with evidence of zoonotic transmission, interspecies recombination, and the lack of approved AdV antivirals or widely available vaccines, HAdVs remain a threat to public health. At the same time, the detailed understanding of AdV biology garnered over nearly 7 decades of study has made this group of viruses a molecular workhorse for vaccine and gene therapy applications.

Abstract
The worldwide burden of cancers is increasing at a very high rate, including the aggressive and resistant forms of cancers. Certain levels of breakthrough have been achieved with the conventional treatment methods being used to treat different forms of cancers, but with some limitations. These limitations include hazardous side effects, destruction of non-tumor healthy cells that are rapidly dividing and developing, tumor resistance to anti-cancer drugs, damage to tissues and organs, and so on. However, oncolytic viruses have emerged as a worthwhile immunotherapeutic option for the treatment of different types of cancers. In this treatment approach, oncolytic viruses are being modeled to target cancer cells with optimum cytotoxicity and spare normal cells with optimal safety, without the oncolytic viruses themselves being killed by the host immune defense system. Oncolytic viral infection of the cancer cells are also being genetically manipulated (either by removal or addition of certain genes into the oncolytic virus genome) to make the tumor more visible and available for attack by the host immune cells. Hence, different variants of these viruses are being developed to optimize their antitumor effects. In this review, we examined how grave the burden of cancer is on a global level, particularly in sub-Saharan Africa, major conventional therapeutic approaches to the treatment of cancer and their individual drawbacks. We discussed the mechanisms of action employed by these oncolytic viruses and different viruses that have found their relevance in the fight against various forms of cancers. Some pre-clinical and clinical trials that involve oncolytic viruses in cancer management were reported. This review also examined the toxicity and safety concerns surrounding the adoption of oncolytic viro-immunotherapy for the treatment of cancers and the likely future directions for researchers and general audience who wants updated information.

Abstract
The development of cancer therapeutics has evolved from general targets with radiation and chemotherapy and shifted toward treatments with a more specific mechanism of action such as small molecule kinase inhibitors, monoclonal antibodies against tumor antigens, or checkpoint inhibitors. Recently, oncolytic viruses (OVs) have come to the forefront as a viable option for cancer immunotherapy, especially for "cold" tumors, which are known to inhabit an immunologically suppressive tumor microenvironment. Desired characteristics of viruses are selected through genetic attenuation of uncontrolled virulence, and some genes are replaced with ones that enhance conditional viral replication within tumor cells. Treatment with OVs must overcome various hurdles such as premature viral suppression by the host's immune system and the dense stromal barrier. Currently, clinical studies investigate the efficacy of OVs in conjunction with various anti-cancer therapeutics, including radiotherapy, chemotherapy, immune checkpoint inhibitors, and monoclonal antibodies. Thus, future research should explore how cancer therapeutics work synergistically with certain OVs in order to create more effective combination therapies and improve patient outcomes.

Abstract
BACKGROUND As a new means of cancer treatment, oncolytic virus has the characteristics of rapid efficacy, strong targeting, and no cytotoxicity. H101, as a commercially marketed oncolytic virus, has shown stable anticancer effect, which provides a possibility for the treatment of peritoneal metastasis in patients with advanced gastric cancer.
AIM To investigate the effects of H101 on proliferation, migration, and apoptosis of gastric cancer cells and the underlying mechanisms.
METHODS The gastric cancer cell lines BGC-823 and SGC-7901were cultured in 6-well plates, and H101 with multiplicity of infection (MOI) values of 1, 5, 10, and 15 were added, respectively. After treatment for 48 h, MTS method was used to detect the cell survival rate, and Western blot was used to detect the expression of E1A. SGC-7901 cells were then selected and cell mobility was detected by the scratch test. Hoechst33342 dye was used to observe the formation of apoptotic bodies after treatment with H101 for 48 h. The expression of apoptosis-related proteins was detected by Western blot.
RESULTS Western blot analysis showed that EIA expression in cells treated with H101 was significantly higher than that in the control group (P < 0.05). MTS assay showed that H101 with an MOI value of 15 could more significantly kill BGC-823 and SGC-79012 cells in vitro than in that with an MOI value of 1 (P < 0.05). After 48 h, the migration distance of cells in the MOI = 5, MOI = 10, and MOI = 15 groups was significantly lower than that of the control group and MOI = 1 group (P < 0.05). Compared with the MOI = 1 group, the MOI = 5, MOI = 10, and MOI = 15 groups had significantly more apoptotic bodies (P < 0.05), and the expression levels of Bcl-2, Bax, and Caspase were significantly higher in the MOI = 5, MOI = 5, and MOI = 10 groups than in the control group and MOI = 1 group (P < 0.05).
CONCLUSION H101 can inhibit the proliferation and migration of gastric cancer cells, increase the expression of apoptosis-related proteins, and accelerate the apoptosis of gastric cancer cells.

Abstract
Background To assess the efficacy and safety of recombinant human adenovirus type 5 (H101) in patients with persistent, recurrent, or metastatic gynecologic malignancies. Methods The study retrospectively enrolled patients with persistent/recurrent/metastatic gynecologic malignancies who received H101-containing treatment at The First Affiliated Hospital of Xi'an Jiaotong University from September 1, 2019 to September 30, 2021. H101 was injected intratumorally into target lesions and dosage was calculated based on tumor diameter once a day for five consecutive days. The primary endpoint was local control (LC) rate. Secondary endpoints included objective response rate (ORR), duration of response (DOR) and progression-free survival (PFS). Safety was the exploratory endpoint. Depending on prior treatment, patients received H101 either as monotherapy or as a combination therapy. Results Totally, 29 patients were enrolled in the study. Median follow-up was 6.3 months (range: 3.2-27.9) from data analysis cut-off on December 31, 2021. The LC rate at 3 months was 44.8%, while ORR was 72.4%. Median DOR and PFS rates were not determined. The DOR rate, PFS rate at 6 and 12 months were 88.1%, 74.6% and 70.5%, 62.2%, respectively. Responses were observed in all four cancer types. Most treatment-related adverse events (90.5%) were grade 1 or 2, with the most common being fever (70%). Clinically significant adverse events were uncommon (7.9% in grade 3 and 1.6% in grade 4). No treatment-related deaths occurred. Conclusion Our study showed that H101 (either monotherapy or combination therapy) has promising efficacy and favorable safety in patients with persistent, recurrent, metastatic gynecologic malignancies.
