(Submitter supplied) Prostate tumors contain foci of neuroendocrine transdifferentiation (NETD), resulting in an increase of androgen-independent neuroendocrine-like (NE) tumor cells, whose number significantly correlates with tumor aggressiveness and a lower survival rate. The mechanisms leading to NETD and the exact role of NE-like tumor cells in disease progression are not fully understood yet. We used microarrays to analyze mRNA and microRNA expression during NE-transdifferentiation and we identified wide changes in both expression profiles including several genes and microRNAs with potential roles in NETD of prostate carcinoma.

(Submitter supplied) Potent therapeutic inhibition of the androgen receptor (AR) in prostate adenocarcinoma can lead to the emergence of neuroendocrine prostate cancer (NEPC), a phenomenon associated with enhanced cell plasticity. Here, we show that microRNA-194 (miR-194) is a regulator of epithelial-neuroendocrine transdifferentiation. In clinical prostate cancer samples, miR-194 expression and activity were elevated in NEPC and inversely correlated with AR signalling. more...

(Submitter supplied) The primary goal of this experiment was to determine the endogenous miRNA that are differentially expressed between prostate adenocarcinoma cells, DU-145 and prostate immortalized epithelial cells, PWR-1E. Subsequently, we performed other analysis with BLAST and in silico algorithm searches to determine the appropriate miRNA that could regulate a novel gene MIEN1.

(Submitter supplied) Twenty-four triple-negative breast cancer and 14 adjacent normal tissues were collected from breast cancer patients during surgeries at National Taiwan University Hospital (NTUH, Taipei, Taiwan). All triple-negative breast cancer samples were invasive ductal carcinomas (IDC) and were negative in immunohistochemical statuses of ER, PR, and HER2 receptors, as confirmed by professional pathologists. Treatment procedure of all patients followed the National Comprehensive Cancer Network (NCCN) guideline. more...

(Submitter supplied) Neuroendocrine prostate cancer (NEPC) is a lethal subtype of prostate cancer (PCa) with hyperchromatic nuclei being a distinguishing histopathological feature. Here we show that, underlying this distinct nuclear structure, heterochromatin related genes are significantly enriched in NEPC. Among them, heterochromatin protein 1α (HP1α) expression is increased early in NE transdifferentiation and is consistently elevated in clinical NEPC samples. more...

(Submitter supplied) Neuroendocrine prostate cancer (NEPC) is a subset of castration-resistant prostate cancer (CRPC) and is thought to derive from prostate adenocarcinoma. However, the cellular basis responsible for Neuroendocrine differentiation (NED) is still under debate. Here, we characterized the tumor cell diversity of 6 CRPC patients using single cell RNA sequencing (scRNA-seq) and detected NED in four patients.

(Submitter supplied) Total RNA was collected from DU145-control(scr) and DU145-miR-106a transfected cells. Gene expression analysis was performed by The Centre for Applied Genomics (The Hospital for Sick Children, Toronto, Canada) using Affymetrix GeneChip Human Gene 2.0 ST array. Data were normalized using the default parameters in Affymetrix Expression Console Software 1.4. Genes downregulated 0.8-fold in miR-106a compared to control(scr) were identified as possible mRNA targets.

(Submitter supplied) MicroRNAs (miRNAs) have been globally profiled in cancers but there tends to be poor agreement between studies including in the same cancers. Additionally, few putative miRNA targets have been validated. To overcome the lack of reproducibility, we profiled miRNAs by next generation sequencing and locked nucleic acid miRNA microarrays, and we verified concordant changes by quantitative RT-PCR. Notably, miR-125b and the miR-99 family members miR-99a, -99b, -100 were down-regulated in all assays in advanced prostate cancer cell lines relative to the parental cell lines from which they were derived. more...

(Submitter supplied) MicroRNAs are small non-coding RNAs that regulate mRNA function. Recent studies have shown that microRNA expression is altered in tumors. We studied the expression of both microRNAs and mRNAs in 60 primary prostate tumors and 16 non-tumor prostate tissues to evaluate the involvement of microRNAs in prostate cancer. Global microRNA expression was determined in RNA isolated from fresh-frozen human tissues with a custom oligonucleotide microarray chip. more...

(Submitter supplied) MicroRNAs (miRNAs) are ~22 nucleotide-long, non-coding RNAs that regulate gene silencing. It is known that many human miRNAs are deregulated in numerous types of tumors. Here we report the sequencing of small RNAs from 23 breast, bladder, colon, and lung tumor samples using high-throughput sequencing. We identified 49 novel miRNA and miRNA-like small RNAs. We further validated the expression of 10 novel small RNAs in 31 different types of blood, normal and tumor tissue samples using two independent platforms, namely microarray and RT-PCR. more...
