Obesity has been identified as a serious health concern in domestic cats. Feline mammary cancer (FMC) is also concern, it highly prevalent and aggressive. Considering the connection between obesity breast cancer, worthwhile to investigate potential obesity–cancer relationship FMC. This review investigated association adipokines other obesity-associated molecules FMC, with aim of identifying gap...

A replication-dependent histone H2A isotype, H2ac, is upregulated in MCF-7 cells and in estrogen receptor-positive clinical breast cancer tissues. Cellular depletion of this H2A isotype leads to defective estrogen signaling, loss of cell proliferation and cell cycle arrest at G0/G1 phase. H2ac mediates regulation of estrogen receptor target genes, particularly BCL2 and c-MYC, by recruiting estr...

The preferential growth of B16 melanoma métastases in specific organs was studied. Following the i.v. injection of B16 melanoma cells into syngeneic C57BL/6 mice, tumor growths developed in the in situ lungs and in grafts of pulmonary or ovarian tissue implanted either s.c. or i.m. In contrast, neoplastic lesions failed to develop in control grafts of similarly im planted renal tissue or at th...

Recent studies indicate that BRCA1, the first breast cancer susceptibility gene to be identified and cloned, interacts with and regulates the activity of estrogen receptor alpha. The availability of genetic tests for BRCA gene mutations has prompted cancer geneticists to generate information about genetic risk and inform women with a personal or family history of breast or ovarian cancer of pre...

Survivin is a key member of the inhibitor of apoptosis protein family, and is considered a promising therapeutic target due to its universal overexpression in cancers. Survivin is implicated in cellular radiation response through its role in apoptosis, cell division, and DNA damage response. In the present study, analysis of publically available data sets showed that survivin gene expression in...

Recent data have shown strong chemopreventive and possibly cancer chemotherapeutic effects of green tea polyphenols and EGCG against breast cancer. This systematic review aims to synthesize data on the possible interaction of green tea catechins with breast cancer endocrine treatment. Electronic databases were searched with the appropriate search terms. Experimental trials suggest a synergistic...

Dear Editor-in-ChiefMalignant melanoma is a tumor arising from melanocyte; this tumor rarely occurs before puberty, with higher mortality rate in males and better survival rate in female patients affected by metastatic melanoma (1, 2). These facts propose that a relationship and association may exist between estrogens and melanoma. The effects of estrogens are mediated by...

The continuous supplementation of mice with supraphysiological doses of estrogen 
for the growth of estrogen receptor-positive breast cancers has been linked to toxicity in the host and perturbation of cancer cells' function that can misguide preclinical studies. Thus, alternative experimental models with circulating levels of estrogens higher than those of mice may represent more suitable host...
