- Recently, a nonsense alteration Trp149Stop in the ARLTS1 gene was found more frequently in familial cancer cases versus sporadic cancer patients and healthy controls. Here, the role of Trp149Stop or any other ARLTS1 germline variant was evaluated on breast, prostate, and colorectal cancer risk. The whole gene was screened for germline alterations in 855 familial cancer patients. The five observed variants were further screened in 1169 non-familial cancer patients as well as in 809 healthy population controls. The Trp149Stop was found at low frequencies (0.5-1.2%) in all patient subgroups versus 1.6% in controls, and the mutant allele did not co-segregate with disease status in families with multiple affected individuals. The CC genotype in the Cys148Arg variant was slightly more common among both familial and sporadic breast (odds ratio (OR), 1.48; 95% confidence interval (CI), 1.16-1.87; P=0.001) and prostate cancer patients (OR, 1.50; 95% CI, 1.13-1.99; P=0.005) when compared to controls. A novel ARLTS1 variant Gly65Val was found at higher frequency among familial prostate cancer patients (8 of 164, 4.9%) than in controls (13 of 809, 1.6%; OR, 3.14; 95% CI, 1.28-7.70, P=0.016). However, after adjusting for multiple testing, none of these results were still significant. No association was found with any of the variants and colorectal cancer risk. Our results suggest that Trp149Stop is not a predisposition allele in breast, prostate, or colorectal cancer in the Finnish population, and, while the Gly65Val variant may increase familial prostate cancer risk and the Cys148Arg change may affect both breast and prostate cancer risk, the evidence is not strong in these data.

- Microseminoprotein-beta (MSMB, MSMB) is an abundant secretory protein contributed by the prostate, and is implicated as a prostate cancer (PC) biomarker based on observations of its lower expression in cancerous cells compared with benign prostate epithelium. However, as the current literature on MSMB is inconsistent, we assessed the expression of MSMB at the protein and mRNA levels in a comprehensive set of different clinical stages of PC. Immunohistochemistry using monoclonal and polyclonal antibodies against MSMB was used to study protein expression in tissue specimens representing prostatectomies (n = 261) and in diagnostic needle biopsies from patients treated with androgen deprivation therapy (ADT) (n = 100), and in locally recurrent castration-resistant PC (CRPC) (n = 105) and CRPC metastases (n = 113). The transcript levels of MSMB, nuclear receptor co-activator 4 (NCOA4) and MSMB-NCOA4 fusion were examined by qRT-PCR in prostatectomy samples and by RNA-sequencing in benign prostatic hyperplasia, PC, and CRPC samples. We also measured serum MSMB levels and genotyped the single nucleotide polymorphism rs10993994 using DNA from the blood of 369 PC patients and 903 controls. MSMB expression in PC (29% of prostatectomies and 21% of needle biopsies) was more frequent than in CRPC (9% of locally recurrent CRPCs and 9% of CRPC metastases) (p<0.0001). Detection of MSMB protein was inversely correlated with the Gleason score in prostatectomy specimens (p = 0.024). The read-through MSMB-NCOA4 transcript was detected at very low levels in PC. MSMB levels in serum were similar in cases of PC and controls but were significantly associated with PC risk when adjusted for age at diagnosis and levels of free or total PSA (p<0.001). Serum levels of MSMB in both PC patients and controls were significantly associated with the rs10993994 genotype (p<0.0001). In conclusion, decreased expression of MSMB parallels the clinical progression of PC and adjusted serum MSMB levels are associated with PC risk.
