Abstract
Androgen receptor signaling regulates the normal and pathological growth of the prostate. In particular, the growth and survival of prostate cancer cells is initially dependent on androgen receptor signaling. Exposure to androgen deprivation therapy leads to the development of castration-resistant prostate cancer. There is a multitude of molecular and cellular changes that occur in prostate tumor cells, including the expression of neuroendocrine features and various biomarkers, which promotes the switch of cancer cells to androgen-independent growth. These biomarkers include transcription factors (TP53, REST, BRN2, INSM1, c-Myc), signaling molecules (PTEN, Aurora kinases, retinoblastoma tumor suppressor, calcium-binding proteins), and receptors (glucocorticoid, androgen receptor-variant 7), among others. It is believed that genetic modifications, therapeutic treatments, and changes in the tumor microenvironment are contributing factors to the progression of prostate cancers with significant heterogeneity in their phenotypic characteristics. However, it is not well understood how these phenotypic characteristics and molecular modifications arise under specific treatment conditions. In this work, we summarize some of the most important molecular changes associated with the progression of prostate cancers and we describe some of the factors involved in these cellular processes.

[PMID: 36685506 PMCID: PMC9845921 DOI: 10.3389/fimmu.2022.1052692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 11/28/2022] [Indexed: 01/05/2023] Open
Abstract
Background Glioma is the most malignant cancer in the brain. As a major vitamin-K-dependent protein in the central nervous system, PROS1 not only plays a vital role in blood coagulation, and some studies have found that it was associated with tumor immune infiltration. However, the prognostic significance of PROS1 in glioma and the underlying mechanism of PROS1 in shaping the tumor immune microenvironment (TIME) remains unclear. Methods The raw data (including RNA-seq, sgRNA-seq, clinicopathological variables and prognosis, and survival data) were acquired from public databases, including TCGA, GEPIA, CGGA, TIMER, GEO, UALCAN, and CancerSEA. GO enrichment and KEGG pathway analyses were performed using "cluster profiler" package and visualized by the "ggplot2" package. GSEA was conducted using R package "cluster profiler". Tumor immune estimation resource (TIMER) and spearman correlation analysis were applied to evaluate the associations between infiltration levels of immune cells and the expression of PROS1. qRT-PCR and WB were used to assay the expression of PROS1. Wound-healing assay, transwell chambers assays, and CCK-8 assays, were performed to assess migration and proliferation. ROC and KM curves were constructed to determine prognostic significance of PROS1 in glioma. Results The level of PROS1 expression was significantly increased in glioma in comparison to normal tissue, which was further certificated by qRT-PCR and WB in LN-229 and U-87MG glioma cells. High expression of PROS1 positively correlated with inflammation, EMT, and invasion identified by CancerSEA, which was also proved by downregulation of PROS1 could suppress cells migration, and proliferation in LN-229 and U-87MG glioma cells. GO and KEGG analysis suggested that PROS1 was involved in disease of immune system and T cell antigen receptor pathway. Immune cell infiltration analysis showed that expression of PROS1 was negatively associated with pDC and NK CD56 bright cells while positively correlated with Macrophages, Neutrophils in glioma. Immune and stromal scores analysis indicated that PROS1 was positively associated with immune score. The high level of PROS1 resulted in an immune suppressive TIME via the recruitment of immunosuppressive molecules. In addition, Increased expression of PROS1 was correlated with T-cell exhaustion, M2 polarization, poor Overall-Survival (OS) in glioma. And it was significantly related to tumor histological level, age, primary therapy outcome. The results of our experiment and various bioinformatics approaches validated that PROS1 was a valuable poor prognostic marker. Conclusion Increased expression of PROS1 was correlated with malignant phenotype and associated with poor prognosis in glioma. Besides, PROS1 could be a possible biomarker and potential immunotherapeutic target through promoting the glioma immunosuppressive microenvironment and inducing tumor-associated macrophages M2 polarization.

IL-6 evoked biochemical changes in prostate cancer cells. Cytokine 2023; 161:156079. [PMID: 36372008 DOI: 10.1016/j.cyto.2022.156079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 10/05/2022] [Accepted: 10/21/2022] [Indexed: 11/12/2022]
Abstract
The pro-inflammatory cytokine IL-6 has been associated with the progression of PCa to a castration-resistant phenotype. In this work, we characterized the biochemical changes evoked by IL-6 in three different models of PCa cells, including LNCaP, C4-2, and PC3. The effect of IL-6 on PCa cells was compared with the effect obtained by co-stimulation with the cAMP-inducing agent forskolin (FSK). Stimulation of LNCaP cells with IL-6 or IL-6 + FSK evoked increased expression of the neuroendocrine marker tubulin IIIβ and Cav3.2 T-type Ca2+ channel subunit. PC3 cells, representing a more advanced state of PCa, had high levels of tubulin IIIβ expression without any further changes observed by treatment with IL-6 or IL-6 + FSK. Elevated expression of the glucocorticoid receptor was observed in PC3, but not in LNCaP or C4-2 cells. Glucocorticoid receptor expression was not regulated by IL-6 stimulation of LNCaP or C4-2 cells. IL-6 acting alone or together with FSK evoked a significant reduction in the expression of the transcription factor REST and retinoblastoma tumor suppressor protein Rb1. In LNCaP cells, IL-6 acting alone or together with FSK had no effect on the expression of several biological markers of advanced PCa, including Aurora kinase A, valosin-containing protein, calcium-sensing receptor, calreticulin, S100A protein, and Protein S. In PC3 cells, co-treatment with IL-6 + FSK evoked increased expression of REST and S100A proteins, as well as a reduction in Protein S levels. These findings reveal a complex pattern of biochemical changes in PCa cells under the influence of IL-6.

Abstract
BACKGROUND AXL, a TAM tyrosine kinase receptor, plays an essential role in the pathogenesis of various solid tumours. This study explores the role of AXL and its ligand PROS1 in the generation and biological behaviour of papillary thyroid cancer (PTC). METHODS The expression levels of AXL in PTC cancer tissue were analysed using immunohistochemistry (IHC) staining. The expression levels of AXL in PTC and normal thyroid cell lines were analysed using real-time quantitative polymerase chain reaction (RT-qPCR). CCK-8 was used to assess the proliferation of the PTC cell line with and without the effect of the AXL inhibitor (R428). Scratching assays played a role in evaluating the cell migration rate. RESULTS PROS1 and AXL were expressed in TPC-1, B-CPAP, and Nthy-Ori 3-1 cells at different levels. Expression was significantly higher in PTC cell lines (TPC-1 and B-CPAP) than in the normal thyroid cell line (Nthy-Ori 3-1) (p < 0.05). In addition, AXL expression in PTC tissues was significantly higher than in adjacent normal tissues (p < 0.05). CCK-8 experiments confirmed that R428 suppresses the proliferation of PTC cell lines in a dose-dependent manner, with an increase in concentration from 0.5 to 4 μM, decreasing the inhibitory effect (p < 0.01). In addition, R428 inhibited PTC cell line migration to different degrees in a range of concentrations from 0.5 to 2 μM compared to control cells (p < 0.01). CONCLUSION PROS1 and its downstream receptor AXL expression were significantly higher in PTC than in normal thyroid cells. AXL expression was also higher in human PTC tissues than in normal thyroid tissues. Inhibiting the PROS1-AXL-mediated TAM signaling pathway via the AXL blocker R428 suppressed the proliferation and migration of human PTC cells, highlighting the role of this cascade in human PTC development and progression.

Abstract
Phylloquinone (vitamin K1) and menaquinones (vitamin K2 family) are essential for post-translational γ-carboxylation of a small number of proteins, including clotting factors. These modified proteins have now been implicated in diverse physiological and pathological processes including cancer. Vitamin K intake has been inversely associated with cancer incidence and mortality in observational studies. Newly discovered functions of vitamin K in cancer cells include activation of the steroid and xenobiotic receptor (SXR) and regulation of oxidative stress, apoptosis, and autophagy. We provide an update of vitamin K biology, non-canonical mechanisms of vitamin K actions, the potential functions of vitamin K-dependent proteins in cancer, and observational trials on vitamin K intake and cancer.

Antioxidants (Basel) 2022; 11:antiox11091633.

Abstract
Although androgen deprivation therapy is mainly used for its treatment, the mortality rate of prostate cancer remains high due to drug resistance. Hence, there is a need to discover new compounds that exhibit therapeutic effects against prostate cancer with minimum side effects. Hesperidin is a flavonoid carbohydrate isolated from citrus fruits. It has antiproliferative effects in various cancer types; however, whether it can modulate cell proliferation by modulating the key targets of cancer therapy, including intracellular signaling pathways and oxidative stress, remains unknown. Therefore, we confirmed that hesperidin suppressed the proliferation of prostate cancer cells, PC3 and DU145. Hesperidin induced cell death by regulating the cell cycle and inhibited the expression of proliferating cell nuclear antigen, a cell proliferation marker. Hesperidin also promoted the generation of reactive oxygen species and induced mitochondrial membrane depolarization and endoplasmic reticulum stress in prostate cancer cells. Moreover, as hesperidin increased Ca2+ levels in prostate cancer cells, we co-treated the inositol 1,4,5-trisphosphate receptor inhibitor, 2-aminoethyl diphenyl borate (2-APB), with hesperidin. Notably, 2-APB restored cell proliferation, which was reduced to control levels by hesperidin. In addition, hesperidin inhibited the activation of the phosphoinositide 3-kinase and mitogen-activated protein kinase signaling pathways. Hesperidin also enhanced the anticancer effects of the chemotherapeutic agent, cisplatin, in both PC3 and DU145 cells. Taken together, these results suggest that hesperidin can be used as a potential therapeutic adjuvant in prostate cancer as it can inhibit cell proliferation by mediating oxidative stress and increasing Ca2+ levels.

BAP1 Loss Promotes Suppressive Tumor Immune Microenvironment via Upregulation of PROS1 in Class 2 Uveal Melanomas. Cancers (Basel) 2022; 14:3678.

Abstract
Uveal melanoma (UM) is the most common primary cancer of the eye and is associated with a high rate of metastatic death. UM can be stratified into two main classes based on metastatic risk, with class 1 UM having a low metastatic risk and class 2 UM having a high metastatic risk. Class 2 UM have a distinctive genomic, transcriptomic, histopathologic, and clinical phenotype characterized by biallelic inactivation of the BAP1 tumor-suppressor gene, an immune-suppressive microenvironment enriched for M2-polarized macrophages, and poor response to checkpoint-inhibitor immunotherapy. To identify potential mechanistic links between BAP1 loss and immune suppression in class 2 UM, we performed an integrated analysis of UM samples, as well as genetically engineered UM cell lines and uveal melanocytes (UMC). Using RNA sequencing (RNA-seq), we found that the most highly upregulated gene associated with BAP1 loss across these datasets was PROS1, which encodes a ligand that triggers phosphorylation and activation of the immunosuppressive macrophage receptor MERTK. The inverse association between BAP1 and PROS1 in class 2 UM was confirmed by single-cell RNA-seq, which also revealed that MERTK was upregulated in CD163+ macrophages in class 2 UM. Using ChIP-seq, BAP1 knockdown in UM cells resulted in an accumulation of H3K27ac at the PROS1 locus, suggesting epigenetic regulation of PROS1 by BAP1. Phosphorylation of MERTK in RAW 264.7 monocyte-macrophage cells was increased upon coculture with BAP1-/- UMCs, and this phosphorylation was blocked by depletion of PROS1 in the UMCs. These findings were corroborated by multicolor immunohistochemistry, where class 2/BAP1-mutant UMs demonstrated increased PROS1 expression in tumor cells and increased MERTK phosphorylation in CD163+ macrophages compared with class 1/BAP1-wildtype UMs. Taken together, these findings provide a mechanistic link between BAP1 loss and the suppression of the tumor immune microenvironment in class 2 UMs, and they implicate the PROS1-MERTK pathway as a potential target for immunotherapy in UM.

Abstract
OBJECTIVE/BACKGROUND Protein S (PS; encoded by the PROS1 gene), a key vitamin K-dependent anticoagulant protein, is emerging as a key structural and functional protein that is overexpressd in various malignancies, but how PS signals to promote lung cancer progression is unclear. METHODS We used immortalized, nontumorigenic human lung epithelial cell line NL-20, A549 cells as experimental cellular models for lung cancer, and human microvascular endothelial cells (HMEC-1) as a model system for angiogenesis. A loss- and gain-of-function approach was then used to analyze the role of tumor-derived PS and their natural TAM receptors Tyro3 and MerTK in regulating cell proliferation, migration, anchorage-independent growth, and capillary-like tube formation, all prominent attributes of the metastatic phenotype of tumor cells. RESULTS Evidence is now provided that regulation of PROS1 gene expression using either stable cell lines expressing lentiviral-short hairpin RNA (shRNAs) or a replication-incompetent adenovirus alters the phosphorylation of several major signaling pathways, including Erk, PKB/Akt, p38, and focal adhesion kinase (FAK), and modulates PS-dependent Tyro3- and MerTK-mediated cell migration, proliferation, and anchorage-independent growth of lung cancer cells, and endothelial cell capillary-like tube formation. CONCLUSION These finding suggest that the PS-Tyro3 and -MerTK axis mediates important signaling pathways to promote lung cancer progression. Genetic inhibition of endogenous PS may serve as a promising target for anticancer drug development.

Abstract
CD14-positive monocytes from patients with rheumatoid arthritis (RA) are more resistant to apoptosis, which promotes their persistence at the inflammatory site and thereby contributes crucially to immunopathology. We sought to elucidate one mechanism underlying this unique pathogenesis: resistance to apoptosis and the potential involvement of miR-29b in this process. CD14-positive peripheral blood monocytes (PBMs) from RA patients were observed to be resistant to spontaneous apoptosis compared to PBMs from healthy volunteers. Intriguingly, expression of miR-29b was significantly upregulated in PBMs from RA patients than those from healthy volunteers, and this upregulation was correlated with RA disease activity. Functionally, forced expression of the exogenous miR-29b in CD14-positive Ctrl PBMs conferred resistance to spontaneous apoptosis and Fas-induced death, thereafter enhancing the production of major proinflammatory cytokines in there cells. Following identification of the potential miR-29b target transcripts using bioinformatic algorithms, we showed that miR-29b could directly bind to the 3'-UTR of the high-mobility group box-containing protein 1 (HBP1) and inhibited its transcription in PBMs. Importantly, stable expression of the exogenous HBP1 in differentiated THP-1 monocytes effectively abolished miR-29b-elicited resistance to Fas-induced apoptosis. Finally, among patients with RA and good clinical responses to immunotherapy, expression levels of miR-29b were significantly compromised in those treated with infliximab (a TNF-α inhibitor) but not in those treated with tocilizumab (a humanized mAb against the IL-6 receptor), pointing to a potential association between miR-29b activation and TNF-α induction. The available data collectively suggest that TNF-α-elicited miR-29b potentiates resistance to apoptosis in PBMs from RA patients via inhibition of HBP1 signaling, and testing patients for miR-29b/HBP1 expression ratios may provide more accurate prognostic information and could influence the recommended course of immunotherapy.

Abstract
Aberrant microRNA (miRNA) expression is a central hallmark of hepatocellular carcinoma (HCC) and identification of the mechanisms underlying the miRNA actions should provide invaluable resource for revealing the molecular basis of different malignant behaviors in HCC. Previous high-throughput analysis has identified miR-767-5p as a unique miRNA signature of HCC, but the biological relevance and corresponding molecular basis of miR-767-5p in HCC is still in its infancy. The current study was, therefore, designed to elucidate whether changes in miR-767-5p expression levels affect HCC pathogenesis, and to further identify the putative targets. miR-767-5p expression was observed to be upregulated by ~ 3.7-fold in surgical HCC specimens as compared to that in adjacent normal hepatic tissues, and this up-regulation trend correlated well to disease progression and predicted a poor prognosis in HCC patients. Functionally, miR-767-5p-overexpressing cells had a significantly higher proliferative, migratory, and invasive potential, and exhibited an enhanced anchorage-dependent clonogenesis and a tumor formation potential in vivo. Mechanistically, PMP22, a core component of integral membrane glycoprotein of peripheral nervous system myelin, was further identified as a direct down-stream target of miR-767-5p in HCC cells. Conversely, stable ectopic expression of PMP22 abrogated the promoting effects of miR-767-5p on HCC aggressive phenotype. Collectively, the available data suggest that as a potent oncomiR, miR-767-5p actions along HCC progression are in part mediated by its function as a posttranscriptional repressor of PMP22 signaling.

Abstract
This study focuses on the effect of miR‐129‐5p on docetaxel‐resistant (DR) prostate cancer (PCa) cells invasion, migration and apoptosis. In our study, the expression of CAMK2N1 was assessed by qRT‐PCR in PCa patient tissues and cell lines including PC‐3 and PC‐3‐DR. Cells transfected with miR‐129‐5p mimics, inhibitor, CAMK2N1 or negative controls (NC) were used to interrogate their effects on DR cell invasions, migrations and apoptosis during docetaxel (DTX) treatments. The apoptosis rate of the PCa cells was validated by flow cytometry. Relationships between miR‐129‐5p and CAMK2N1 levels were identified by qRT‐PCR and dual‐luciferase reporter assay. CAMK2N1 was found to be down‐expressed in DR PCa tissue sample, and low levels of CAMK2N1 were correlated with high docetaxel resistance and clinical prediction of poor survival. CAMK2N1 levels were decreased in DR PCa cells treated with DXT. We further explored that up‐regulation of miR‐129‐5p could promote DR PCa cells viability, invasion and migration but demote apoptosis. Involved molecular mechanism studies revealed that miR‐129‐5p reduced downstream CAMK2N1 expression to further impact on chemoresistance to docetaxel of PCa cells, indicating its vital role in PCa docetaxel resistance. Our findings revealed that miR‐129‐5p contributed to the resistance of PC‐3‐DR cells to docetaxel through suppressing CAMK2N1 expression, and thus targeting miR‐129‐5p may provide a novel therapeutic approach in sensitizing PCa to future docetaxel treatment.

Abstract
Malignant gliomas are the most common primary brain tumors. Due to both their invasive nature and resistance to multimodal treatments, these tumors have a very high percentage of recurrence leading in most cases to a rapid fatal outcome. Recent data demonstrated that neural stem/progenitor cells possess an inherent ability to migrate towards glioma cells, track them in the brain and reduce their growth. However, mechanisms involved in these processes have not been explored in-depth. In the present report, we investigated interactions between glioma cells and neural stem/progenitor cells derived from the subventricular zone, the major brain stem cell niche. Our data show that neural stem/progenitor cells are attracted by cultured glioma-derived factors. Using multiple approaches, we demonstrate for the first time that the vitamin K-dependent factor protein S produced by glioma cells is involved in tumor tropism through a mechanism involving the tyrosine kinase receptor Tyro3 that, in turn, is expressed by neural stem/progenitor cells. Neural stem/progenitor cells decrease the growth of both glioma cell cultures and clonogenic population. Cultured neural stem/progenitor cells also engulf, by phagocytosis, apoptotic glioma cell-derived fragments and this mechanism depends on the exposure of phosphatidylserine eat-me signal and is stimulated by protein S. The disclosure of a role of protein S/Tyro3 axis in neural stem/progenitor cell tumor-tropism and the demonstration of a phagocytic activity of neural stem/progenitor cells towards dead glioma cells that is regulated by protein S open up new perspectives for both stem cell biology and brain physiopathology.

Abstract
PURPOSE Although the interferon α (IFNα) signaling and the paired-like homeodomain transcription factor 2 (PITX2) have both been implicated in the progression of breast cancer (BCa), it remains obscure whether these two pathways act in a coordinated manner. We therefore aimed to elucidate the expression and function of PITX2 during the pathogenesis of endocrine resistance in BCa. MATERIALS AND METHODS PITX2 expression was assessed in BCa tissues using quantitative reverse transcription polymerase chain reaction (RT-qPCR) and immunohistochemistry and in experimentally induced letrozole-resistant BCa cells using RT-qPCR and immunoblotting. Effects of PITX2 deregulation on BCa progression was determined by assessing MTT, apoptosis and xenograft model. Finally, using multiple assays, the transcriptional regulation of interferon-inducible transmembrane protein 1 (IFITM1) by PITX2 was studied at both molecular and functional levels. RESULTS PITX2 expression was induced in letrozole-resistant BCa tissues and cells, and PITX2 induction by IFNα signaling powerfully protected BCa cells against letrozole insult and potentiated letrozole-resistance. Mechanistically, PITX2 enhanced IFNα-induced AKT activation by transactivating the transcription of IFITM1, thus rendering BCa cells unresponsive to letrozoleelicited cell death. Additionally, ablation of IFITM1 expression using siRNA substantially abolished IFNα-elicited AKT phosphorylation, even in the presence of PITX2 overexpression, thus sensitizing BCa cells to letrozole treatment. CONCLUSION These results demonstrate that constitutive upregulation of PITX2/IFITM1 cascade is an intrinsic adaptive mechanism during the pathogenesis of letrozole-resistance, and modulation of PITX2/IFITM1 level using different genetic and pharmacological means would thus have a novel therapeutic potential against letrozole resistance in BCa.

Abstract
IMPACT STATEMENT Cancer is among the leading causes of death worldwide. In 2016, 8.9 million people are estimated to have died from various forms of cancer. The current treatments, including surgery with chemotherapy and/or radiation therapy, are not effective enough to provide full protection from cancer, which highlights the need for developing novel therapy strategies. In this review, we summarize the molecular biology of a unique member of a subfamily of receptor tyrosine kinase, TYRO3 and discuss the new insights in TYRO3-targeted treatment for cancer therapy.

Abstract
Insights into the mechanisms by which key factors stimulate cell growth under androgen-depleted conditions is a premise to the development of effective treatments with clinically significant activity in patients with castration-resistant prostate cancer (CRPC). Herein, we report that, the expression of Krüppel-like factor 14 (KLF14), a master transcription factor in the regulation of lipid metabolism, was significantly induced in castration-insensitive PCa cells and tumor tissues from a mouse xenograft model of CRPC. KLF14 upregulation in PCa cells, which was stimulated upstream by oxidative stress, was dependent on multiple pathways including PI3K/AKT, p42/p44 MAPK, AMPK and PKC pathways. By means of ectopic overexpression and genetic inactivation, we further show that KLF14 promoted cell growth via positive regulation of the antioxidant response under androgen-depleted conditions. Mechanistically, KLF14 coupled to p300 and CBP to enhance the transcriptional activation of HMOX1, the gene encoding the antioxidative enzyme heme oxygenase-1 (HO-1) that is one of the most important mechanisms of cell adaptation to stress. Transient knockdown of HMOX1 is sufficient to overcome KLF14 overexpression-potentiated PCa cell growth under androgen-depleted conditions. From a pharmacological standpoint, in vivo administration of ZnPPIX (a specific inhibitor of HO-1) effectively attenuates castration-resistant progression in the mouse xenograft model, without changing KLF14 level. Together, these results provide comprehensive insight into the KLF14-dependent regulation of antioxidant response and subsequent pathogenesis of castration resistance and indicate that interventions targeting the KLF14/HO-1 adaptive mechanism should be further explored for CRPC treatment.

Abstract
OBJECTIVE The mainstay of treatment for advanced bladder cancer (BC) is cisplatin (CDDP)-based systematic chemotherapy. However, acquired chemoresistance induced by as yet unidentified mechanisms is encountered frequently and often results in treatment failure and disease progression. The present study was designed to elucidate the expression and potential role of the gene associated with retinoid-interferon-induced mortality-19 (GRIM19) in the pathogenesis of CDDP resistance in BC. METHODS RT-qPCR and immunoblotting were employed to evaluate the expression profile of GRIM19 in clinical BC samples and in different BC cells. Using cell viability assay, apoptotic ELISA, xenografts mouse model, and Transwell assay, the effects of GRIM19 inhibition or GRIM19 overexpression on CDDP resistance were determined in different BC cells. Lastly, using co-immunoprecipitation, we provided the molecular evidence for the interaction between GRIM19 and Bcl-xL. RESULTS Expression levels of GRIM19 were significantly down-regulated in recurrent BC specimens, and in experimentally induced CDDP-resistant BC cells. Functionally, overexpression of the exogenous GRIM19 potentiated CDDP sensitivity and suppressed the survival and invasion of BC cells in the presence of CDDP challenge. Mechanistically, the compromised CDDP chemosensitization induced by GRIM19 loss was at least partially attributed to the attenuation of Bcl-xL polyubiquitination and subsequent degradation, because (1) GRIM19 colocalized with Bcl-xL in the mitochondria of BC cells and (2) GRIM19 overexpression promoted the ubiquitination of Bcl-xL, and this event could be effectively reversed by pretreatment with inhibitors of p38-MAPK and JNK pathways, indicating that GRIM19 overexpression-induced Bcl-xL ubiquitination may achieve in a p38/JNK-dependent manner. Using the UMUC-3 cells stably depleted of endogenous GRIM19, we further show that inhibition of Bcl-xL rectified GRIM19 deficiency-caused CDDP resistance in BC cells. In addition, BCL2L1 mRNA levels were negatively correlated with GRIM19 mRNA levels in CDDP-associated clinical BC tissues. CONCLUSIONS Disruption of GRIM19/Bcl-xL is a key mechanism of CDDP resistance in advanced BC. Therapeutically, enhancement of GRIM19 expression or employment of p38/JNK inhibitors may serve as resensitizing therapies for subgroups of CDDP-resistant or refractory BC patients.

Urology 2018; 123:296.e9-296.e18. [PMID: 29730257 DOI: 10.1016/j.urology.2018.04.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2017] [Revised: 03/26/2018] [Accepted: 04/25/2018] [Indexed: 12/23/2022]
Abstract
OBJECTIVE To reveal the potential role of the basic helix-loop-helix myogenic transcription regulator MyoD in the regulation of castration-resistant prostate cancer. METHODS Expression level of MyoD was assessed in prostate cancer tissues using quantitative reverse transcription polymerase chain reaction and immunohistochemistry and in experimentally induced castration-resistant LNCaP/R cells using quantitative reverse transcription polymerase chain reaction and immunoblotting. Effect of MyoD knockdown on LNCaP/R cell progression was determined by assessing cell proliferation, apoptosis, and colony formation rate. The effect of MyoD knockdown on the oxidative stress state in PC3 cells was determined by assessing antioxidant response gene expression and glutathione synthetase-to-glutathione ratio. Finally, the functional link between the nuclear factor erythroid-derived 2-related factor 1 (NRF1) and the regulation of antioxidant response element-driven transcription by MyoD was studied at both molecular and functional levels. RESULTS MyoD expression was significantly upregulated in hormone-refractory prostate cancer tissues and in experimentally induced castration-resistant LNCaP/R cells, and MyoD knockdown effectively impaired LNCaP/R cell proliferation and promoted apoptosis under androgen-depleted condition. Moreover, MyoD enhanced the glutathione production and protected against oxidative stress by positively regulating a cluster of antioxidant genes known to be the downstream targets of NRF1. Mechanistically, MyoD could augment the antioxidant response element-driven transcription in an NRF1-dependent manner, and the stimulatory effect of MyoD on the antioxidant response was substantially compromised in the presence of NRF1 small interfering RNA treatment. CONCLUSION We have identified an unexpected collaboration between MyoD and NRF1 under androgen-depleted condition, which may serve as an important adaptive mechanism during the pathogenesis of castration-resistant prostate cancer.

Abstract
Type 2 diabetes mellitus (T2DM) promotes a high oxidative stress and hypercoagulable state that drives microvascular injury and multiple-organ abnormality. Elevated thrombin activity underlies T2DM-linked endothelial dysfunction, but the mechanistic links between T2DM/oxidative stress axis and thrombin-associated endothelial pathologies are incompletely understood. In this work, immunohistochemical studies and quantitative analysis using isolated endothelial cells (ECs) identified accumulated Kru¨ppel-like family of transcription factor 14 (KLF14) deposits in ECs from multiple organs as distinct features of T2DM mice. KLF14 upregulation in ECs, which was stimulated by thrombin treatment, was dependent on multiple pathways including calcium mobilization, activation of PKC and AMPK pathways. Functionally, inhibition of endogenous KLF14 expression significantly attenuated thrombin-induced endotheliocyte proliferation, endothelial cell migration and oxidative stress. Molecularly, by directly binding the promoter, KLF14 functions as a transcriptional activator of PLK1, a polo-like kinase whose overexpression induced excessive reactive oxygen species (ROS) production. Transient knockdown of PLK1 was sufficient to suppress KLF14 overexpression-potentiated endothelial dysfunction. Collectively, these data provide proof of concept that deregulation of KLF14/PLK1 cascade plays a key role in thrombin-induced endothelial dysfunction and targeting KLF14 or PLK1 may limit thrombin-associated pathologies in T2DM patients.

Abstract
Attenuation of estrogen receptor α (ERα) expression via unknown mechanism(s) is a hallmark of endocrine-resistant breast cancer (BCa) progression. Here, we report that miR-1271 was significantly down-regulated in letrozole-resistant BCa tissues and in letrozole-resistant BCa cells. miR-1271 directly targeted the chromatin of DNA damage-inducible transcript 3 (DDIT3) gene. miR-1271 expression level was inversely correlated to DDIT3 mRNA level in BCa biopsies. Form a mechanistic standpoint, reintroduction of exogenous miR-1271 could effectively restore ERα level via inhibiting DDIT3 expression, thereby potentiating letrozole sensitivity in BCa cells. Moreover, DDIT3 deregulation promoted letrozole-resistance by acting as a potent corepressor of ESR1 transcription. Taken together, we have identified that disruption of the miR-1271/DDIT3/ERα cascade plays a causative role in the pathogenesis of letrozole resistance in BCa.

Abstract
OBJECTIVE To identify the potential downstream targets of hsa-miR-125a-3p, a mature form of miR-125a, during the pathogenesis of chemoresistance in prostate cancer (PCa). MATERIALS AND METHODS The expression levels of hsa-miR-125a-3p were assessed in chemoresistant PCa tissues and experimentally established chemoresistant cells using quantitative reverse transcription-polymerase chain reaction. The effect of hsa-miR-125a-3p knockdown or hsa-miR-125a-3p overexpression on the Dox-induced cell death was evaluated using apoptosis ELISA in chemosensitive PC-3 cells or in chemoresistant PC-3 cells (PC-3R). Finally, using multiple assays, the regulation of metastasis-associated protein 1 (MTA1), an essential component of the Mi-2-nucleosome remodeling deacetylation complex, by hsa-miR-125a-3p was studied at both molecular and functional levels. RESULTS The expression of hsa-miR-125a-3p was significantly downregulated in chemoresistant PCa tissues and cells. Inhibition of hsa-miR-125a-3p significantly increased docetaxel (Dox) resistance in PC-3 cells, whereas upregulation of hsa-miR-125a-3p effectively reduced Dox resistance in PC-3R, suggesting that this microRNA (miRNA) may act as a tumor suppressor along the pathogenesis of drug resistance. Mechanistically, hsa-miR-125a-3p induced apoptosis and Dox sensitivity in PCa cells through regulating MTA1. CONCLUSION Our results collectively indicate that miRNA-MTA1 can form a delicate regulatory loop to maintain a bistable state in the Dox chemosensitivity, and future endeavor in this filed should provide important clues to develop miRNA-based therapies that benefit advanced PCa patients through modulating the functional status of MTA1.

Abstract
Acquired resistance to classical chemotherapeutics such as docetaxel (DTX) remains a critical challenge in breast cancer (BCa) treatment. Epigenetic modification by microRNAs (miRNAs) has been shown to play a crucial role in cancer drug resistance. Previous study, using human drug-resistant BCa tissues, has identified miR-638 as one of the most down-regulated miRNAs, but its exact roles and underlying mechanisms during the pathogenesis of chemoresistance remain to be determined. In the current study, we found that miR-638 expression was significantly down-regulated in clinical DTX-resistant BCa tissues compared to that in DTX-sensitive BCa tissues. By using the previously established DTX-resistant MCF-7 cells (MCF-7/R), we also confirmed that chemoresistant cells displayed decreased levels of miR-638. To provide the direct functional evidence, we inhibited and overexpressed miR-638 in different cell lines. Thereby, the cells were rendered more resistant or susceptible to DTX treatment. Mechanistically, the lipid-binding protein STARD10 was identified as a miR-638 target mediating the DTX-resistance. Hence, we provide a molecular explanation for acquired resistance to DTX that is caused by the miR-638 deficiency and subsequent STARD10 upregulation. In consequence, alteration of miR-638/STARD10 cascade may represent an attractive strategy in future adjuvant therapy along with DTX chemotherapy.

Abstract
Emerging but limited data have evidenced an essential involvement of microRNAs (miRNAs) in the development and progression of triple negative breast cancer (TNBC), which empowers these small regulators as an innovative therapeutic approach, especially for this unique tumor subgroup still lacking an efficient and specific therapeutic target. Herein, we reported the down-regulation of miR-34c-3p level in TNBC tissues, and its expression was closely associated with estrogen receptor alpha (ERα), but not other receptors, in well-characterized breast cancer (BCa) cells. Functionally, ectopic expression of miR-34c-3p inhibited migration, invasion and epithelial-mesenchymal transition (EMT) in TNBC cells. From a mechanistic standpoint, bioinformatics coupled with luciferase and gain-of-function, loss-of-function assays showed that miR-34c-3p may regulate TNBC progression by directly targeting the 3'-untranslated region (UTR) of mitogen-activated protein kinase kinase kinase 2 (MAP3K2). Consistently, MAP3K2 overexpression could effectively rescue miR-34c-3p mimics-induced suppression of cell invasion and EMT. In light of these findings, miR-34c-3p may function as a tumor suppressor in regulating of TNBC invasiveness and EMT through negatively modulating MAP3K2 pathway. Future endeavor in this field may help to identify a novel biomarker to predict prognosis and response to therapy in TNBC.

Abstract
Many prostate cancer (PCa) recurrences are thought to be due to reactivation of disseminated tumor cells (DTCs). We previously found a role of the TAM family of receptor tyrosine kinases TYRO3, AXL, and MERTK in PCa dormancy regulation. However, the mechanism and contributions of the individual TAM receptors is largely unknown. Knockdown of MERTK, but not AXL or TYRO3 by shRNA in PCa cells induced a decreased ratio of P-Erk1/2 to P-p38, increased expression of p27, NR2F1, SOX2, and NANOG, induced higher levels of histone H3K9me3 and H3K27me3, and induced a G1/G0 arrest, all of which are associated with dormancy. Similar effects were also observed with siRNA. Most importantly, knockdown of MERTK in PCa cells increased metastasis free survival in an intra-cardiac injection mouse xenograft model. MERTK knockdown also failed to inhibit PCa growth in vitro and subcutaneous growth in vivo, which suggests that MERTK has specificity for dormancy regulation or requires a signal from the PCa microenvironment. The effects of MERTK on the cell cycle and histone methylation were reversed by p38 inhibitor SB203580, which indicates the importance of MAP kinases for MERTK dormancy regulation. Overall, this study shows that MERTK stimulates PCa dormancy escape through a MAP kinase dependent mechanism, also involving p27, pluripotency transcription factors, and histone methylation. J. Cell.

Abstract
The Metastasis-associated protein 1 (MTA1) coregulator, an essential component of the nucleosome remodeling and deacetylase (NuRD) complex, potentiates neuroprotective effects against ischemia/reperfusion (I/R) injury. But the underlying mechanism(s) remain largely unknown. Here, we discovered that neuronal MTA1 was a target of oxidative stress, and stimulation of neurons with oxygen glucose deprivation (OGD) treatment significantly inhibited MTA1 expression. Additionally, MTA1 depletion augmented ischemic oxidative stress and thus promoted oxidative stress-induced neuronal cell death by OGD. While studying the impact of MTA1 status on global neuronal gene expression, we unexpectedly discovered that MTA1 may modulate OGD-induced neuronal damage via regulation of distinct nitric oxide synthase (NOS) (namely neuronal NOS, nNOS) signaling. We provided in vitro evidence that NOS1 is a chromatin target of MTA1 in OGD-insulted neurons. Mechanistically, neuronal ischemia-mediated repression of NOS1 expression is accompanied by the enhanced recruitment of MTA1 along with histone deacetylases (HDACs) to the NOS1 promoter, which could be effectively blocked by a pharmacological inhibitor of the HDACs. These findings collectively reveal a previously unrecognized, critical homeostatic role of MTA1, both as a target and as a component of the neuronal oxidative stress, in the regulation of acute neuronal responses against brain I/R damage. Our study also provides a molecular mechanistic explanation for the previously reported neurovascular protection by selective nNOS inhibitors.

Abstract
Epigenetic gene inactivation by microRNAs (miRNAs) plays a key role in malignant transformation, prevention of apoptosis, drug resistance and metastasis. It has been shown that miR-125a is down-regulated in HER2-amplified and HER2-overexpressing breast cancers (BCa), and this miRNA is believed to serve as an important tumor suppressor. miR-125a has two mature forms: hsa-miR-125a-3p and hsa-miR-125a-5p. However, the functional details of these miRNAs in BCa, particularly during pathogenesis of drug resistance, remain largely unexplored. Herein, we reported that hsa-miR-125a-3p expression was significantly reduced in chemoresistant BCa tissues and in experimentally established chemoresistant BCa cells. hsa-miR-125a-3p knockdown promoted cell proliferation and compromised docetaxel (Dox)-induced cell death, whereas overexpression of hsa-miR-125a-3p attenuated Dox chemoresistance in BCa cells. From a mechanistic standpoint, hsa-miR-125a-3p directly targeted 3'-untranslated regions (3'-UTRs) of breast cancer early onset gene 1 (BRCA1) and inhibits its protein expression via translational repression mechanism. In addition, suppression of BRCA1 expression by siRNA treatment effectively improved hsa-miR-125a-3p deficiency-triggered chemoresistance in BCa cells. Collectively, these findings suggest that hsa-miR-125a-3p may function as a tumor suppressor by regulating the BRCA1 signaling, and reintroduction of hsa-miR-125a-3p analogs could be a potential adjunct therapy for advanced/chemoresistant BCa.
