Previous studies have suggested that salivary amylase and proline-rich protein are sorted differently when expressed in AtT-20 cells (Castle, A.M., L.E. Stahl, and J.D. Castle. 1992. J. Biol. Chem. 267:13093- 13100; Colomer, V., K. Lal, T.C. Hoops, and M.J. Rindler. 1994.EMBO (Eur. Mol. Biol. Organ.) J. 13:3711- 3719). We now show that both exocrine proteins behave similarly and enter the regul...

GRP94 (glucose-regulated protein of 94 kDa) is a major luminal constituent of the endoplasmic reticulum with known high capacity for calcium in vivo and a peptide-binding activity in vitro. In the present study, we show that Ca2+ regulates the ability of GRP94 to bind peptides. This effect is due to a Ca2+-binding site located in the charged linker domain of GRP94, which, when occupied, enhance...

The transition from normal forage to a highly fermentable diet to achieve rapid weight gain in the cattle industry can induce ruminal acidosis. The molecular host mechanisms that occur in acidosis are largely unknown. Therefore, the histology and transcriptome profiling of rumen epithelium was investigated in normal and acidosis animals to understand the molecular mechanisms involved in the dis...

Objective Genetic and morphologic similarities between mouse embryonic stem cell (ESCs) and Primordial Germ Cell (PGCs) make it difficult to distinguish the two cell types in in vitro differentiation. Using the expression of specific markers of germ cells that are not expressed or expressed at low levels in ESCs, can help recognizing in vitro differentiated cells MaterialsAndMethods In this stu...

Ubiquitin - proteasome system (UPS), the major protein degradation pathway in the cells, typically degrades short - lived and damaged proteins and regulates growth and stress responses. This pathway is altered in various cancers, including Acute Lymphoblastic Leukemia (ALL). ALL begins with a change in bone marrow cells and is the most common type of leukemia in children under 15 years. UBE2Q1...

endoplasmic reticulum has a critical role in the synthesis and folding of secretory and membrane proteins. high accumulation of proteins in er activates the unfolded protein response and glucose regulated protein 78 or gpr78 plays an essential role in this pathway.  unfolded protein response is activated in cancerous cells due to their adverse condition to survive and it has been shown that grp...
