Environmental control of mammary carcinoma cell expansion by acidification and spheroid formation in vitro.

Breast cancer is the leading cause of cancer death among women worldwide. Like other cancers, mammary carcinoma progression involves acidification of the tumor microenvironment, which is an important factor for cancer detection and treatment strategies. However, the effects of acidity on mammary carcinoma cell morphology and phenotype have not been thoroughly characterized.

The Rat Mammary Gland as a Novel Site of Expression of Melanin-Concentrating Hormone Receptor 1 mRNA and Its Protein Immunoreactivity.

Lactation is a complex physiological process, depending on orchestrated central and peripheral events, including substantial brain plasticity. Among these events is a novel expression of pro-melanin-concentrating hormone () mRNA in the rodent hypothalamus, such as the ventral part of the medial preoptic area (vmMPOA). This expression reaches its highest levels around postpartum day 19 (PPD19), when dams transition from lactation to the weaning period.

Histopathologic Changes in Placental Tissue Associated With Vertical Transmission of Zika Virus.

Zika virus (ZIKV) is highly neurotropic after crossing the placenta, inducing teratogenic effects that result in delayed development and microcephaly in infants. The available evidence for vertical transmission of this infection is based on placental studies showing alterations in trophoblastic tissue. However, complete characterization of ZIKV-infected placenta and involved pathways has yet to be fully clarified.

Metastatic melanoma positively influences pregnancy outcome in a mouse model: could a deadly tumor support embryo life?

The incidence of melanoma is increasing worldwide. It is one of the leading cancers in pregnancy and the most common malignancy to metastasize to placenta and fetus. There are no publications about experimental models of melanoma and pregnancy.
