While screening for protein kinases expressed in the murine mammary gland, we identified previously a Ca2+/calmodulin-dependent kinase, Pnck, that is most closely related to CaMKI. In this report, we show that Pnck is temporally regulated during murine mammary development with highest levels of expression observed late in pregnancy, concomitant with the decreased cellular proliferation and term...
Periostin (POSTN), a recently characterised matricellular protein, is frequently dysregulated in various malignant cancers and promotes tumor metastatic growth. POSTN plays a critical role in the crosstalk between murine breast cancer stem cells (CSCs) and their niche to permit metastatic colonization. However, whether pro-metastatic capability of POSTN is associated with multipotent potentials...
BACKGROUND:Canine mammary gland cancers are the most prevalent malignancies in dogs. There are different challenges regarding management of these cancers in dogs and human, one hypothesis is related to small cellular subset of tumor mass called cancer stem cell. These cells are therapy resistant and cause metastasis and relapse even after primary successful treatment. The well-identified phenot...
Cellular identity and differentiation are determined by epigenetic programs. The characteristics of these programs in normal human mammary epithelium and their similarity to those in stem cells are unknown. To begin investigating these issues, we analyzed the DNA methylation and gene expression profiles of distinct subpopulations of mammary epithelial cells by using MSDK (methylation-specific d...
objective: objective: dermal papilla and hair epithelial stem cells regulate hair formation and growth cycle. damage to or losing of these cells can cause hair loss. although several studies have claimed to reconstitute hairs using rodent cells in animal model, a stable human hair follicle reconstitution protocol needs more studies. here in this study we evaluated hair induction through injecti...
We have developed a method for sustained growth of human mammary epithelial cells in monolayer cultures. Epithelial organoids derived from solid breast tissues were grown on the surface of thin (approximately 1 mm) collagen gel layers in an enriched growth medium supplemented with hormones, growth factors, fetal calf serum, and horse serum. To transfer the cultures, the collagen layers were dis...
Fetal and neonatal exposure to long-chain alkylphenols has been suspected to promote breast developmental disorders and consequently to increase breast cancer risk. However, disease predisposition from developmental exposures remains unclear. In this work, human MCF-10A mammary epithelial cells were exposed in vitro to a low dose of a realistic (4-nonylphenol + 4-tert-octylphenol) mixture. Tran...

The aim of this study was to consider effect of increasing metabolizable energy and protein during late pregnancy on mammary growth and development in sistani goats. Twenty eight pregnant sistani goats with same average body weight and 2 year old age were selected and randomly assigned to four groups at beginning of late pregnancy period (d 100 of pregnancy): 1- Control group with recommendatio...
