New human prostate cell lines were developed from prostatic carcinoma (BRF-41T) and BPH (BRF-55T). Primary cultures were initiated from cellular outgrowths of explanted tissues. A serum-free medium, BRFF-HPC1, was developed for growing human prostatic cancer cells. Cell strains were immortalized with pRSV-T plasmid to generate permanent cell lines that exhibited an epithelial morphology. Both cell lines expressed the epithelial cell markers, cytokeratins 8 and 18 as well as the prostatic marker, PSA, and the androgen receptor gene. They possess the H-ras, K-ras, and p53 genes. We hope that these new human prostatic cell lines will be useful as in vitro models for cancer research.

Quantitative and structural genetic alterations cause the development and progression of prostate cancer. A number of genes have been implicated in prostate cancer by genetic alterations and functional consequences of the genetic alterations. These include the ELAC2 (HPC2), MSR1, and RNASEL (HPC1) genes that have germline mutations in familial prostate cancer; AR, ATBF1, EPHB2 (ERK), KLF6, mitochondria DNA, p53, PTEN, and RAS that have somatic mutations in sporadic prostate cancer; AR, BRCA1, BRCA2, CHEK2 (RAD53), CYP17, CYP1B1, CYP3A4, GSTM1, GSTP1, GSTT1, PON1, SRD5A2, and VDR that have germline genetic variants associated with either hereditary and/or sporadic prostate cancer; and ANXA7 (ANX7), KLF5, NKX3-1 (NKX3.1), CDKN1B (p27), and MYC that have genomic copy number changes affecting gene function. More genes relevant to prostate cancer remain to be identified in each of these gene groups. For the genes that have been identified, most need additional genetic, functional, and/or biochemical examination. Identification and characterization of these genes will be a key step for improving the detection and treatment of prostate cancer.

Genes involved in cancer generation are usually tumor suppressors and oncogenes. Progressive genetic alterations in these genes are involved in the mechanisms of tumorigenesis. In prostate cancer, additionally several chromosomal loci that should harbor mutated genes have been proposed. Some genes have been found altered in prostate cancer, such as PTEN, TP53, AR, RNASEL (HPC1), ELAC2 (HPC2), CDKN2A and MSR1 and those can be natural targets for new strategies of treatment. Besides, gene therapy has been suggested to be suitable for prostate cancer treatment. This approach includes ex vivo corrective therapy, suicide, and antisense therapy.
