HLA-BAT1 alters migration, invasion and pro-inflammatory cytokines in prostate cancer.

Prostate cancer (PCa) accounts for more than 1 in 5 diagnoses and is the second cause of cancer-related deaths in men. Although PCa may be successfully treated, patients may undergo cancer recurrence and there is a need for new biomarkers to improve the prediction of prostate cancer recurrence and improve treatment. Our laboratory demonstrated that HLA-B-associated transcript 1 (BAT1) was differentially expressed in patients with high Gleason scores when compared to low Gleason scores.

Andrographolide induces DNA damage in prostate cancer cells.

Prostate cancer (PCa) is the most common diagnosed cancer and is the third cause of cancer mortality in men in the USA. Andrographolide, a diterpenoid lactone isolated from Andrographis paniculata, has shown to possess anticarcinogenic activity in a variety of cancer cells. In this study, we examined the efficacy of Andrographolide in PCa using and models.

IL-15 regulates migration, invasion, angiogenesis and genes associated with lipid metabolism and inflammation in prostate cancer.

Prostate cancer (PCa) is the most commonly diagnosed non-cutaneous cancer. In the United States it is second leading cause of cancer related deaths in men. PCa is often treated via radical prostatectomy (RP).

Mitochondrial DNA Integrity Is Maintained by APE1 in Carcinogen-Induced Colorectal Cancer.

Changes in mitochondrial DNA (mtDNA) integrity have been reported in many cancers; however, the contribution of mtDNA integrity to tumorigenesis is not well understood. We used a transgenic mouse model that is haploinsufficient for the apurinic/apyrimidinic endonuclease 1 () gene, which encodes the base excision repair (BER) enzyme APE1, to determine its role in protecting mtDNA from the effects of azoxymethane (AOM), a carcinogen used to induce colorectal cancer. Repair kinetics of AOM-induced mtDNA damage was evaluated using qPCR after a single AOM dose and a significant induction in mtDNA lesions in colonic crypts from both wild-type (WT) and animals were observed.

Oral HPV infection in a clinic-based sample of Hispanic men.

Background: Human papillomavirus (HPV) is associated to the pathogenesis of various cancers, such as oropharyngeal squamous cell carcinoma, which has a high incidence in Puerto Rican men. Despite the burden of oral cancer in Puerto Rico, little is known about the epidemiology of oral HPV infection, particularly in high-risk men. Therefore, this study is aimed at determining the prevalence of oral HPV infection, the genotype distribution and correlates associated with oral HPV infection in men of at least 16 years of age attending a sexually transmitted infection (STI) clinic in Puerto Rico.
