(Submitter supplied) The androgen receptor (AR) is a therapeutic target of prostate cancer (PCa). Targeted AR therapy commonly uses androgen deprivation therapy (ADT) and AR antagonists to reduce androgen levels and inhibit tumor growth. Surprisingly, treatment with supraphysiological androgen level (SAL) can also inhibit the growth of PCa. SAL (R1881) was shown to induce cellular senescence in PCa. Knockdown of BHLHE40 in C4-2 and LNCaP cell lines indicates that BHLHE40 mediates SAL-induced cellular senescence as a possible tumor suppressive pathway. more...

(Submitter supplied) The bipolar androgen therapy (BAT) to treat prostate cancer includes cycles of supraphysiological androgen levels (SAL) under continuous androgen deprivation therapy (ADT). We showed previously that SAL induces cellular senescence in androgen-sensitive PCa cells and ex vivo in PCa tumor samples from patients that underwent radical prostatectomy. Here, we show that SAL induces cellular senescence in both, castration sensitive (CSPC) LNCaP and castration resistant PCa (CRPC) C4-2 cells through the cell cycle inhibitor p15. more...

(Submitter supplied) The catalytic subunit of the human telomerase (hTERT) is activated during tumorigenesis in many cancers including prostate cancer (PCa). Androgens mediate their effect through the androgen receptor (AR), a key factor controlling PCa growth. hTERT expression is known to be regulated by androgens, however contrarily observed to be inhibited or activated. Here, we reveal that androgens repress or activate hTERT expression in a concentration-dependent manner. more...

(Submitter supplied) Colorectal cancer is one of the most frequent and lethal cancer in the world. Current therapeutic approaches are still not fully successful, yet cause numerous and severe side effects for the patient. We screened chemically synthesized derivatives from two natural compounds (a-Mangostin and Paeonol) as potential novel chemicals that increase cancer cell selectivity over non-transformed human cells. We found two of them that efficiently induced cell cycle arrest and apoptosis in human cancer cells and organoids derived from tumor tissue without affecting the viability of human non-cancer cells and intestinal organoids derived from healthy tissue. Our findings increase the knowledge about cancer-specific compounds and propose two natural compound derivatives as potential novel chemotherapeutics.

(Submitter supplied) Knockdown of BHLHE40 expression significantly reduced primary tumor growth and spontaneous lung metastasis in an orthotopic xenograft model of human breast cancer. Gene expression analysis implicated a role of BHLHE40 in hypoxia-induced exosomic secretion of Heparin Binding Epidermal Growth Factor HBEGF, which promotes cell survival and invasion. BHLHE40 induces HBEGF transcription by blocking DNA binding of HDAC1 and HDAC2.

(Submitter supplied) The androgen receptor (AR) plays a key role in progression to incurable androgen-ablation resistant prostate cancer (PCA). We have identified three novel AR splice variants lacking the ligand binding domain (designated as AR3, AR4 and AR5) in hormone insensitive PCA cells. AR3, one of the major splice variants expressed in human prostate tissues, is constitutively active and its transcriptional activity is not regulated by androgens or antiandrogens. more...

(Submitter supplied) Whether the nuclear fraction of mTOR plays a role in prostate cancer (PCa) and can participate in direct transcriptional crosstalk with the androgen receptor (AR) is as yet unknown. The intersection of gene expression, DNA binding-events, and metabolic studies uncovered the existence of a nuclear mTOR-AR transcriptional axis dictating the metabolic rewiring and nutrient usage of PCa cells. In human clinical specimens, nuclear localization of mTOR was significantly associated with metastasis and castration-resistant PCa (CRPC), correlating with a sustained metabolic gene program governed by mTOR in that context. more...

(Submitter supplied) Androgen receptor (AR) orchestrates an intricate transcriptional regulatory network that governs prostate cancer initiation, development and progression. To understand this network in detail, we generated genome-wide maps of AR occupancy by ChIP-seq in LNCaP cells. We found NKX3-1, an androgen-dependent homeobox protein well-characterized for its role in prostate development and differentiation, being recruited to AR binding sites (ARBS) in response to androgen signaling. more...

(Submitter supplied) Androgen receptor (AR) plays an essential role in normal prostate development and prostate cancer (PCa) progression. To understand the role of AR at the single-cell level, we performed single-cell transcriptome analysis on PCa cells stimulated with androgen and antiandrogen to reconstruct the dynamic and direct AR transcriptional network. Our work reveals that androgen stimulates the ER and Golgi stress response , promoting secreting protein trafficking, and inhibiting cell apoptosis. more...

(Submitter supplied) Androgen receptor (AR) plays key roles both in development of normal prostate gland and at all stages of prostate cancer. Due to the diversity of cell response to androgen stimulation, it’s necessary to investigate AR regulatory network at single cell level to fully understand how AR regulates transcription in prostate cancer cells. Here, we performed anti-androgen drug treated single cell RNA-seq profiling and transcriptome analysis on prostate cancer cell lines following 5α-dihydrotestosterone (DHT) stimulation. more...
