Establishment and characterization of a human prostatic carcinoma cell line (PC-3).
TLDR
The establishment, characterization, and tumorigenicity of a new epithelial cell line (PC-3) from a human prostatic adenocarcinoma metastatic to bone is reported, which should be useful in investigating the biochemical changes in advanced prostatic cancer cells and in assessing their response to chemotherapeutic agents.Abstract:
The establishment, characterization, and tumorigenicity of a new epithelial cell line (PC-3) from a human prostatic adenocarcinoma metastatic to bone is reported The cultured cells show anchorage-independent growth in both monolayers and in soft agar suspension and produce subcutaneous tumors in nude mice Culture of the transplanted tumor yielded a human cell line with characteristics identical to those used initially to produce the tumor PC-3 has a greatly reduced dependence upon serum for growth when compared to normal prostatic epithelial cells and does not respond to androgens, glucocorticoids, or epidermal or fibroblast gowth factors Karyotypic analysis by quinacrine banding revealed the cells to be completely aneuploid with a modal chromosome number in the hypotriploid range At least 10 distinctive marker chromosomes were identified The overall karyotype as well as the marker chromosomes are distinct from those of the HeLa cell Electron microscopic studies revealed many features common to neoplastic cells of epithelial origin including numerous microvilli, junctional complexes, abnormal nuclei and nucleoli, abnormal mitochondria, annulate lamellae, and lipoidal bodies Overall, the functional and morphologic characteristics of PC-3 are those of a poorly-differentiated adenocarcinoma These cells should be useful in investigating the biochemical changes in advanced prostatic cancer cells and in assessing their response to chemotherapeutic agentsread more

c-Jun N-terminal kinase mediates apoptotic signaling induced by N-(4-hydroxyphenyl)retinamide.
TL;DR: Results suggest that the JNK pathway mediates 4-HPR-induced apoptotic signaling, which is suppressed by curcumin, which inhibits JNK activation and Expression of dominant-negative mutants in the J NK pathway inhibited 4- HPR- induced apoptosis in human embryonic kidney 293 cells.

TL;DR: A functional role for miR-21-3p in ovarian cancer and other solid tumors is suggested, and immunohistochemical analyses of serous ovarian cancer patient samples suggest a significant decrease of RBMPS levels when compared to normal ovarian epithelium.

Chromosomal Analysis of Human Prostatic Adenocarcinoma Cell Lines
TL;DR: Banding analysis of PC-5-PI isolated from primary prostatic adenocarcinoma indicated that this line also had a characteristic karyotype with 28% pseudodiploid and 72% pseudotetraploid components.

Modulation of liver X receptor signaling as novel therapy for prostate cancer
TL;DR: The potential use of LXR signaling as a therapeutic target in prostate and other cancers is examined and phytosterols, the plant equivalent of mammalian cholesterol, have been shown to be agonists for LXRs.

Role of the MDR-1-Encoded Multiple Drug Resistance Phenotype in Prostate Cancer Cell Lines

TL;DR: The chemoresistant and hormone-insensitive PC-3 and Du-145 cell lines express P-gp and exhibit verapamil-sensitive drug efflux, indicative of MDR, and the low MDR-reversal rates observed in these cell lines in response to chemosensitizers point to non-MDR-associated cellular mechanisms as dominant factors of chemoresistance in prostate cancer.
