The p21 belongs to the CIP/KIP family of CDK inhibitors involved in cell cycle arrest at specific stages of the cell cycle progression. DNA methylation is the best studied epigenetic mark that have been evidently associated to chromatin condensation, and repression of gene transcription. The CpG island hypermethylation in promoter region of certain genes occurs in cancer cells and affects tumor...
Purpose: Skin is continuously exposed to many hazardous environmental factors such as ultraviolet radiation (UV). Many investigations have been shown to cause skin damages. The aim of present research was to study the effect of a single time of UVB radiation on the expression pattern of keratinocyte growth factor (KGF) gene in mice. Materials and Methods: UVB (30 mJ/cm2 and 50 mJ/cm2) were rad...
Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...
Background: Deregulation of FOXO3a gene which belongs to Forkhead box O (FOXO) transcription factors, can cause cancer (e.g. breast cancer). FOXO factors have important role in ubiquitination, acetylation, de-acetylation, protein-protein interactions and phosphorylation. Understanding the regulation and mechanisms of FOXO3a can lead to cancer treatment. The aim of this study recent association...
Previous studies have shown that WRKY transcription factors play important roles in abiotic stress responses. Thus, virus-induced gene silencing (VIGS) was used to identify the function of SlWRKY79 salt tolerance tomato plants by downregulating expression gene. Under same treatment conditions, SlWRKY79-silenced showed faster stem wilting and more severe leaf shrinkage than control plants, bendi...
Salvia miltiorrhiza Bunge is a common Chinese herbal medicine, and its major active ingredients are phenolic acids tanshinones, which widely used to treat vascular diseases. However, the wild form of S. possess low levels these important pharmaceutical agents; thus, improving their an area research. Transcription factors, promote or inhibit expressions multiple genes involved in one more biosyn...
The nuclear pore complex is a multiprotein comprising approximately 30 different proteins called nucleoporins (Nups). Recent studies in yeast, animals, and plants have shown that the Nups bind to chromatin interact with transcription factors, chromatin-remodeling histone-modifying enzymes, structural proteins, including CCCTC-binding factor cohesin. These findings suggest provide subnuclear pla...
background:the zinc-finger x linked (zfx) gene encodes a transcription factor that acts as a regulator of self-renewal of stem cells. due to the role of zfx in cell growth, understanding zfx protein-protein interactions helps to clarify its proper biological functions in signaling pathways. the aim of this study is to define zfx protein-protein interactions and the role of zfx in cell growth. m...
Injuries to the musculoskeletal system are common, debilitating and expensive. In many cases, healing is imperfect, which leads to chronic impairment. Gene transfer might improve repair and regeneration at sites of injury by enabling the local, sustained and potentially regulated expression of therapeutic gene products such products include morphogens, growth factors and anti-inflammatory agent...
Background: The herpes simplex virus (HSV) UL41 gene product, virion host shutoff (Vhs) protein, mediates the rapid degradation of both viral and cellular mRNA. This ability suggests that Vhs protein can be used as a suicide gene in cancer gene therapy applications. The recent reports have shown that the degradation of cellular mRNA during herpes simplex infection is selective. RNA containing A...
