The growing incidence of prostate cancer has prompted a great investment in basic biology and translational studies to develop new therapies. Multiple animal models have been established to study etiological factors, cancer-preventive strategies and the molecular determinants of aggressiveness and metastases. The rat model of prostate cancer induced by chemical carcinogen N-methyl-N-nitrosourea (MNU) and testos...
This work aimed to understand how lifelong exercise training promotes the remodelling of the immune system and prostate signalome in a rat model of PCa. Fifty-five male Wistar rats were divided into four groups: control sedentary, control exercised, induced PCa sedentary and induced PCa exercised. Exercised animals were trained in a treadmill for 53 weeks. Pca induction consisted on the sequential administratio...
Material & Methods: Fifty-five male Wistar rats were divided into: control sedentary (SED+CONT; n=10), control exercised (EX+CONT; n=10), induced sedentary (SED+PCa; n=15), and induced exercised (EX+PCa; n=20). Exercised animals were trained in a treadmill, for 53 weeks. PCa induction consisted of flutamide and N-methyl-N-nitrosourea administration, followed by testosterone propionate implants. At sacrifice, pr...
Immune system and prostate signalome in a rat model of prostate cancer: influence of lifelong exercise training
Background: Prostate cancer (PCa) is among the most prevalent cancers worldwide. This work aimed to under- stand the effects of exercise training in a rat model of PCa chemically and hormonally-induced. Material and Methods: Fifty-five male Wistar rats were divided into: control sedentary (SED+CONT; n=10), control exercised (EX+CONT; n=10), induced seden- tary (SED+PCa; n = 15) and induced exercised (EX+PCa; n=...
MODERATE INTENSITY TREADMILL EXERCISE INFLUENCES THE IMMUNE SYSTEM AND PROSTATE SIGNALOME IN A RAT MODEL OF PROSTATE CANCER
Immune system and prostate signalome in a rat model of prostate cancer: influence of lifelong exercise training
Background and Aim: Male hypogonadism results from failure to produce physiological levels of testosterone. Testosterone in men is essential in masculine development, sperm production, and adult man’s health. Osteoporosis is one of the consequences of hypogonadism. Regular physical exercise and exogenous testosterone administration are frequently used to prevent or treat this condition. This study aimed to unde...
Prostate cancer (PCa) is one of the most common cancers in men, with a huge impact on their health. The use of Castanea sativa Mill. flowers (CFs) in beverages has been reported, through ancestral claims, as having health benefits. In vitro research has evidenced the properties of CFs, such as antitumor and anti- oxidant activities. This study aimed to evaluate the effects of CF extract in an animal model of PC...
Background: Prostate is the largest accessory gland of the male reproductive tract. The prostate of men over 40 years- old is frequently affected by several pathologies, like benign prostate hyperplasia and cancer. Rats have been used as model to study prostate cancer. This study intended to address the usefulness of ultrasonography for rat prostate monitoring. Materials and Methods: Eight male Wistar Unilever ...
