Glutathione, cell proliferation and differentiation

  All organisms require an equivalent source for living. Reduced glutathione is the most abundant thiol containing protein in mammalian cells and organs. Glutathione was discovered by Hopkins in 1924 who published his findings in JBC. It is a three peptide containing glutamic acid, cystein and glycin and is found in reduced and oxide forms in cell. High concentration of glutathione and its high reduced/oxide...

TNF-α expression, not iNOS expression, is correlated with NF-κB activation in the spinal cord of rats following peripheral nerve injury

  Previous studies have shown that pro-inflammatory cytokines were involved in the genesis and persistence of neuropathic pain. Nuclear factor kappa B (NF-κB) plays a crucial role in regulating pro-inflammatory cytokine gene expression. In this study, we examined the hypothesis that NF-κB would regulate the expression of spinal tumor necrosis factor α (TNF-α) and inducible nitric...

A nonsense (c.3978G>A) abnormal spindle-like, microcephaly associated (ASPM) gene mutation is a major cause of primary microcephaly in Pashtoon ethnic group of Pakistan

  Primary microcephaly (MCPH) is an autosomal-recessive congenital disorder characterized by smaller-than-normal brain size and mental retardation. MCPH is genetically heterogeneous with six known loci: MCPH1 to MCPH7. The abnormal spindle-like, microcephaly associated (ASPM) gene at MCPH5 locus, which accounts for 37 to 54% of MCPH, appears to be the most common cause of microcephaly. More than 50% of the MCPH...

Genome scanning for identification of resistance gene analogs (RGAs) in a highly durable blast resistance rice (Oryza sativa L.) cultivar, Moroberekan

  Disease resistance in plants is a desirable economic trait. Many disease resistance genes from various plants have been cloned so far. The gene products of some of these can be distinguished by the presence of an N terminal nucleotide binding site and a C-terminal stretch of leucine-rich repeats. Oligonucleotides already designed from sequence motifs conserved between resistance N genes of tobacco...
