Regulation of Follicular Growth and Development in Sheep
This manuscript reviews the present knowledge related to folliculogenesis in sheep.Folliculogenesis starts with formation of primordial follicles before birth, present as a pool containing a certain number of follicles. By the attainment of puberty, a group of follicles from that pool starts to grow, a process known as primordial follicle activation or recruitment. The number of growing primord...
متن کاملRegulation of vascular endothelial growth factor by the Wnt and K-ras pathways in colonic neoplasia.
Angiogenesis is not restricted to advanced stages of tumor development but is also observed in benign precursor lesions. Vascular endothelial growth factor (VEGF) is a key regulator of tumor angiogenesis, but the genetic mechanisms controlling its expression in premalignant lesions are poorly described. The Wnt signaling pathway, which is commonly mutated in benign colonic adenomas, was found t...
متن کاملUrinary Transforming Growth Factors in Neoplasia: Separation
Purified human epidermal growth factor (hEGF) from urine promotes anchorage-independent cell growth in soft agar medium. This growth is enhanced by transforming growth factor-/} (TGF-/8), and is specifically inhibited by hEGF antiserum. Transforming growth factors of the a type (TGF-a), potentially present in normal human urine or urine from tumorbearing patients, also promote anchorage-indepen...
متن کاملCancer Prevention Research Regulation of Prostaglandin Transporters in Colorectal Neoplasia
Prostaglandin E2 (PGE2) promotes cancer progression by affecting cell proliferation, apoptosis, angiogenesis, and the immune response. It has been reported that PGE2 is transported or passes through the cell membrane via prostaglandin-specific transporters including the prostaglandin transporter (PGT, an influx transporter) and the multidrug resistance-associated protein 4 (an efflux transporte...
