Recent studies indicated that the estrogen receptor beta (ER beta) could affect the progression of prostate and bladder tumors, however, its roles in the renal cell carcinoma (RCC), remain to be elucidated. Here, we provide clinical evidence that ER beta expression is correlated in a negative manner with the overall survival/disease-free survival in RCC patients. Mechanism dissection revealed that targeting ER beta with ER beta-shRNA and stimulating the transactivation of ER beta with 17 beta-estradiol or environmental endocrine disrupting chemicals, all resulted in altering the lncRNA HOTAIR expression. The ER beta-modulated HOTAIR is able to function via antagonizing several microRNAs, including miR-138, miR-200c, miR-204, or miR-217 to impact various oncogenes, including ADAM9, CCND2, EZH2, VEGFA, VIM, ZEB1, and ZEB2, to promote RCC proliferation and invasion. Together, the identification of the ER beta-HOTAIR axis may provide us new biomarkers and/or therapeutic targets to better suppress RCC progression in the future.

ASC-J9® suppresses prostate cancer cell proliferation and invasion via altering the ATF3-PTK2 signaling

Hao Tian, Fu-ju Chou, Jing Tian, Yong Zhang, Bosen You, Chi-Ping Huang, Shuyuan Yeh, Yuanjie Niu, Chawnshang Chang

Summary: ASC-J9 (R) can suppress prostate cancer progression via an androgen receptor-independent mechanism by altering ATF3 expression, leading to decreased PTK2 expression. Clinical and preclinical studies support the role of ATF3/PTK2 signaling in PCa progression.

Androgen receptor promotes renal cell carcinoma (RCC) vasculogenic mimicry (VM) via altering TWIST1 nonsense-mediated decay through lncRNA-TANAR

Bosen You, Yin Sun, Jie Luo, Keliang Wang, Qing Liu, Ruizhe Fang, Bingmei Liu, Fuju Chou, Ronghao Wang, Jialin Meng, Chi-Ping Huang, Shuyuan Yeh, Chawnshang Chang, Wanhai Xu

Summary: The study suggests that androgen receptor (AR) promotes vasculogenic mimicry (VM) formation in ccRCC cells by regulating lncRNA-TANAR/TWIST1 signals, potentially impacting metastasis. This discovery provides a clue for the development of a novel anti-angiogenesis therapy to better suppress ccRCC progression.

Androgen receptor decreases renal cell carcinoma bone metastases via suppressing the osteolytic formation through altering a novel circEXOC7 regulatory axis

Dongkui Gong, Yin Sun, Changcheng Guo, Tzong-jen Sheu, Wei Zhai, Junhua Zheng, Chawnshang Chang

Summary: The study revealed gender differences in RBM, with higher AR expression potentially linked to fewer RBMs by suppressing osteolytic formation. Mechanism dissection showed that AR can decrease circEXOC7 expression by enhancing transcription of DHX9, leading to suppression of CSF1 expression. Results from clinical epidemiological surveys found positive correlation between AR and miR-149-3p, and negative correlation between AR and CSF1 in AR-positive ccRCC tissues.

Targeting androgen receptor (AR) with antiandrogen Enzalutamide increases prostate cancer cell invasion yet decreases bladder cancer cell invasion via differentially altering the AR/circRNA-ARC1/miR-125b-2-3p or miR-4736/PPARγ/MMP-9 signals

Gang Deng, Ronghao Wang, Yin Sun, Chi-Ping Huang, Shuyuan Yeh, Bosen You, Changyong Feng, Gonghui Li, Shenglin Ma, Chawnshang Chang

Summary: Targeting androgens/androgen receptor signals can affect the invasion capability of prostate cancer and bladder cancer cells, with prostate cancer cell invasion increasing while bladder cancer cell invasion decreasing. This difference may be due to the distinct alterations in selective circular RNAs resulting from differential endogenous AR transcription, along with differential histone H3K4 methylation patterns and binding of AR to different androgen-response elements.

Summary: The study identified that lnc-OPHN1-5 plays a role in increasing prostate cancer sensitivity to Enzalutamide by regulating AR protein expression. The mechanism involves lnc-OPHN1-5 interacting with AR-mRNA to influence ribosome association and translation by modulating hnRNPA1.

Targeted activation of androgen receptor signaling in the periosteum improves bone fracture repair

Summary: The study found that androgen receptor (AR) is highly expressed in periosteum cells during bone fracture repair and is co-localized with a mesenchymal progenitor cell marker, Prrx1. Mice lacking AR in periosteum showed reduced callus size and new bone volume. Targeting the androgen/AR axis in periosteum may provide a novel therapy approach to improve fracture healing.

Targeting circDGKD Intercepts TKI's Effects on Up-Regulation of Estrogen Receptor β and Vasculogenic Mimicry in Renal Cell Carcinoma

Jie Ding, Xin-Gang Cui, Hao-Jie Chen, Yin Sun, Wei-Wei Yu, Jie Luo, Guang-Qian Xiao, Chawnshang Chang, Jun Qi, Shuyuan Yeh

Summary: Vasculogenic mimicry (VM), an alternative channel for tumor nutrient supply, is associated with poor prognosis in renal cell carcinoma (RCC). Sunitinib, a tyrosine kinase inhibitor (TKI), has been reported to induce VM formation by up-regulating estrogen receptor beta (ERβ) expression. This study showed that treatment with sunitinib and another TKI, axitinib, also induced ERβ expression in RCC cell lines. Clinical RCC patients with higher ERβ expression were more likely to have VM. Mechanistically, TKI-induced ERβ up-regulated the circular RNA DGKD, which enhanced VM formation by increasing VE-cadherin expression. Targeting circDGKD intercepted sunitinib-induced RCC VM formation and improved survival in an animal model.

High-dose-androgen-induced autophagic cell death to suppress the Enzalutamide-resistant prostate cancer growth via altering the circRNA-BCL2/miRNA-198/AMBRA1 signaling

Lei Chen, Yin Sun, Min Tang, Denglong Wu, Zhendong Xiang, Chi-Ping Huang, Bosen You, Dongdong Xie, Qinglin Ye, Dexin Yu, Chawnshang Chang

Summary: This study found that high-dose androgens can suppress the growth of Enzalutamide-resistant (EnzR) castration-resistant prostate cancer (CRPC) cells. The mechanism involves the transcriptional regulation of the circRNA-BCL2 host gene BCL2, which in turn affects the expression of miRNA-198 and modulates the expression of AMBRA1. This leads to the induction of autophagic cell death and the suppression of EnzR CRPC cell growth.

Estrogen and G protein-coupled estrogen receptor accelerate the progression of benign prostatic hyperplasia by inducing prostatic fibrosis

Yang Yang, Jindong Sheng, Shuai Hu, Yun Cui, Jing Xiao, Wei Yu, Jing Peng, Wenke Han, Qun He, Yu Fan, Yuanjie Niu, Jun Lin, Ye Tian, Chawnshang Chang, Shuyuan Yeh, Jie Jin

Summary: This study identified the histopathological characteristics and molecular mechanisms underlying accelerated progression of benign prostatic hyperplasia (BPH). Increased stromal components and prostatic fibrosis, accompanied by higher myofibroblast accumulation and collagen deposition, were found to be the main features of accelerated progressive BPH tissues. Mechanism dissection revealed that higher expression of CYP19 and G protein-coupled estrogen receptor (GPER) with higher estrogen biosynthesis contribute to the progression of BPH. Targeting the CYP19/estrogen/GPER/G alpha i signaling axis may provide new personalized therapeutics for better suppressing the progression of BPH.
