In farm animals, both genetic and non-genetic factors affect reproductive traits. These can be categorized as intrinsic extrinsic. Extrinsic relate to the animal’s environment, while are related its genotype. Various traits studied concerning age, season, management, nutrition, body score, birth type. addition, variations of transforming growth factor-β (TGFβ) superfamily including BMPR-1B, BMP...

UNLABELLED The TGFβ superfamily regulates a broad range of cellular processes, including proliferation, cell-fate specification, differentiation, and migration. Molecular mechanisms underlying this high degree of pleiotropy and cell-type specificity are not well understood. The TGFβ family is composed of two branches: (i) TGFβs, activins, and nodals, which signal through SMAD2/3, and (ii) bone ...

Squamous cell carcinomas occurring at transition zones are highly malignant tumors with poor prognosis. The identity of the cell population and the signaling pathways involved in the progression of transition zone squamous cell carcinoma are poorly understood, hence representing limited options for targeted therapies. Here, we identify a highly tumorigenic cancer stem cell population in a mouse...

The plasticity of differentiated cells in adult tissues undergoing repair is an area of intense research. Pulmonary alveolar type II cells produce surfactant and function as progenitors in the adult, demonstrating both self-renewal and differentiation into gas exchanging type I cells. In vivo, type I cells are thought to be terminally differentiated and their ability to give rise to alternate l...

To date, the glycoprotein endoglin and its receptor complex, formed between TGFβ and TGFβR-2, have been studied in tumor angiogenesis. The purpose of this study is to investigate the expression profile of endoglin and its receptor complex in human atherosclerotic lesions, and compare it to that in non-atherosclerotic tissues. Twenty-six atherosclerotic lesions and twenty-six non-atherosclerotic...
