NKX3.1 is a multifaceted protein with roles in prostate development and protection from oxidative stress. Acting as a pioneer factor, NKX3.1 interacts with chromatin at enhancers to help integrate androgen regulated signalling. In prostate cancer, NKX3.1 activity is frequently reduced through a combination of mutational and post-translational events. Owing to its specificity for prostate tissue, NKX3.1 has found use as an immunohistochemical marker in routine histopathology practice.

Biomarkers Of Oxidative Stress

AbstractProstate cancer is the most common non-cutaneous cancer and the second leading cause of cancer-related mortality among men in the USA. Growing evidence suggests that oxidative stress is involved in the development and progression of prostate cancer. In this study, the association between antioxidants from diet and supplements and biomarkers of oxidative stress in blood (n 278), urine (n 298) and prostate tissue (n 55) were determined among men from the North Carolina-Louisiana Prostate Cancer Project. The association between antioxidant intake and oxidative stress biomarkers in blood and urine was determined using linear regression, adjusting for age, race, prostate cancer aggressiveness and smoking status. Greater antioxidant intake was found to be associated with lower urinary 8-isoprostane concentrations, with a 10 % increase in antioxidant intake corresponding to an unadjusted 1·1 % decrease in urinary 8-isoprostane levels (95 % CI −1·7, −0·3 %; P value<0·01) and an adjusted 0·6 % decrease (95 % CI −1·4, 0·2 %; P value=0·16). In benign prostate tissue, thioredoxin 1 was inversely associated with antioxidant intake (P=0·02). No significant associations were found for other blood or urinary biomarkers or for malignant prostate tissue. These results indicate that antioxidant intake may be associated with less oxidative stress among men diagnosed with prostate cancer.

Molecular Pathophysiology

: Prostate Cancer (PC) is one the most prominent cause of deaths in males worldwide especially in western countries. The exhaustive research into prostate cancer to date has demonstrated ELAC2, RNASEL, MSR1, NBS1, CHEK2, MYC, BCL-2, c-Kit, tumor suppressor genes, BRCA1, BRCA2, PACE4, GSTP1, PTEN,CDKN1B, NKX3.1, KLF6, FOXA1, Retinoblastoma, p53, androgen receptor, kallikreins, ETS, CYP17, SRD5A2, E-cadherin, KAI1/CD82, hepsin, AMACR, PIM1, MTA-1, EZH2, EPHB2, growth factors & its receptors, cannabinoid receptors, annexins, oxidative stress and inflammation are entailed changes underlying the initiation, development, and progression of PC. Furthermore, oncology would shift from a reactive to proactive discipline so exploring these targets open new area of research. Therefore, the present review is focused on molecular pathophysiology biomarkers for the progression of PC that would encourage the researchers and pharmaceutical industries to investigate potential therapeutic strategy to overcome demerits of currently available clinically therapies.

ABSTRACT Background Mycoplasma hominis, an opportunistic pathogen in human genitourinary tract, can cause chronic infection in the prostate. Intracellular survival of M. hominis leads to a prolonged presence in the host cells that can affect the cell's biological cycle. In the present study, we aimed to evaluate the frequency of M. hominis DNA in prostate tissue of Iranian patients with prostate cancer (PCa) in comparison to a control group with benign prostatic hyperplasia (BPH). Methods This research was a retrospective case-control study using 61 archived formalin-fixed paraffin-embedded (FFPE) blocks of prostate tissue from patients with PCa and 70 FFPE blocks of patients with BPH. Real-time PCR, targeting two different genes, 16S rRNA and yidC, in the M. hominis genome was performed for all specimens. Results Out of 61 blocks of prostate biopsy from patients with PCa, eight samples (13%) were positive for M. hominis, while the bacterium was not detected in any of the 70 blocks of patients with BPH (P value, 0.002). Conclusions The high frequency of M. hominis in patients with PCa likely shows a hidden role of the organism in prostate cancer during its chronic, apparently silent and asymptomatic colonization in prostate.
