Cancer is a complex disease with multiple causes. Many intrinsic and extrinsic factors influence the development of cancer. Intrinsic or host factors include age, sex, genetics, immune system, metabolism, and hormones. Extrinsic factors are divided in different groups, as physical (different types of non-ionizing and ionizing radiations); chemical (as some mineral or organic substances); and biological (produce...
Background: Teratomas are rare types of germ cell neoplasms composed of various differentiated or undifferentiated tissues. Case Description: A 25-week-old female control FVB /n mouse in a 4-week toxicity study presented abdominal distension and poor body condition. It was euthanized, and the necropsy examination revealed a large mass connected to the tip of the right uterine horn, occupying the entire abdomina...
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...
Chemopreventive effects of Santolina chamaecyparissus in a rat model of chemically- induced mammary cancer
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=...
