Aging, as a major risk factor of memory deficiency, affects neural signaling pathways in hippocampus. In particular, age-dependent androgens deficiency causes cognitive impairments. Several enzymes like protein kinase C (PKC) are involved in memory deficiency. Indeed, PKC regulatory process mediates α-secretase activation to cleave APP in β-amyloid cascade and tau proteins phosphorylation mecha...

hereditary inclusion body myopathy (hibm) is an adult-onset hereditary myopathy, usually with distal onset and quadriceps sparing. this myopathy is autosomal recessive and associated to upd-n-acetylglucosamine-2-epimerase/n-acetylmannosamine kinase (gne) gene mutations. in this study, we report a novel gne homozygous point mutation c.1834t>g that results in amino acid substitution of cysteine 6...

microtubule affinity-regulating kinase 2 (mark2) protein has a substantial role in regulation of vital cellular processes like induction of polarity, regulation of cell junctions, cytoskeleton structure and cell differentiation. the abnormal function of this protein has been associated with a number of pathological conditions like alzheimer disease, autism, several carcinomas and development of...

beauveria spp. as entomopathogenic fungi have extremely diverse insect host ranges.here, a comparative transcript analysis of a bassiasin i (bsni), a dipeptidyl peptidase (dpp), a cytochrom p450 monooxygenase (cyp52), a mitogen activated protein kinase (mapk), and a neuronal calcium sensor 1 (ncs) in two isolates of beauveria bassiana., with low and high virulence, were carried out. for this, i...

objective(s): acquisition of tnf-α resistance plays role in the onset and growth of malignant tumors. previous studies have demonstrated that mcf-7 cell line and its doxorubicin resistant variant mcf-7/adr are resistant against the cytotoxic effects of tnf-α. in this study, we investigated the role of akt activation in resistance of mcf-7 and mcf-7/adr against tnf-α cytotoxicity. materials and ...

nitric oxide (no) is thought to be involved in spatial learning and memory in several brain areas such as hippocampus. this study examined the effects of post-training intrahippocampal microinjections of 1400w as a selective inducible nitric oxide synthase (inos) inhibitor on spatial memory, in both anesthetized and non-anesthetized situations in rats. in the present work, 4-day training trials...

Abstract: Aim: LK (B-lymphocyte kinase) is a protein from the family SRC (Proto-oncogene tyrosine-protein kinase), an important cell signaling molecule that influences cellular response. The BLK kinase has been potential target for cancer therapy. As result, this could be initial step toward development of novel inhibitors to fight cancer. Materials and Methods: A homology model human tyrosine ...

Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in travelers, young children and piglets, but the precise pathogenesis of ETEC induced diarrhea is not fully known. Recent investigations have shown that tight junction (TJ) proteins and aquaporin 3 (AQP 3) are contributing factors in bacterial diarrhea. In this study, using immunoblotting and immunohistochemistry analyses, we found that E...

background: the purpose of this study is to evaluate effects of teucrium polium (tp) leaf extracts on adenosine monophosphate activated protein kinase (ampk) level in isolated pancreases. materials and methods: in this experimental study, two groups of rats were used as a control group, and diabetic group. in the end of experimental period the animals were sacrificed then pancreas were removed,...
