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

Metastatic properties of the human prostatic cell line, PPC-1, in athymic nude mice.
TL;DR: The recently isolated primary prostatic carcinoma cell line, PPC-1, has been shown to be tumorigenic in athymic nude mice and is likely to represent a good model system for the study of human prostate cancer progression.

Modulation of mitochondrial aconitase on the bioenergy of human prostate carcinoma cells.
TL;DR: This study demonstrated the key role of the mACON in the cellular bioenergy and cell proliferation of human prostate carcinoma cells and blocked 40-60% mACon expression and enzymatic activity which induced decrease in the intracellular ATP biosynthesis but increase citrate secretion in the human prostate cancer cells.

TL;DR: Two conjugated lytic peptide sequences designed to target luteinizing hormone-releasing hormone receptors have specificity for and anti-proliferative activity against tumor cells, and low toxicity for normal prostate cells, which suggest these peptides could serve as a new type of therapy for prostate cancer.

TL;DR: S100A1 and S100B expression is proposed as a marker to develop potency assays for cartilage regeneration cell therapies, and as a redifferentiation readout in monolayer cultures aiming to investigate stimuli for chondrogenic induction.
