In TNF signaling pathway,TRAF2 as adapter proteins and regulation factors are important to nearly all pathways,having a key role in mediating TNF-R1-induced activation of NF-κB and JNK.
Objective To detect the correlation of cell cycle regulation factors Cyclin D1, CDK4, P16 protein and p16 gene expression with clinicopathologic features and prognosis in colorectal carcinoma.
5. Immunocytochemistry and in situ hybridization analysis revealed that PDT resulted in an induction of G1/S checkpoint regulation factors such as Chk2 and p21WAF1/Cip1/Sdi1,and a down-regulation of cyclinD1 in a time-dependent fashion.
To study the effect of the cell cycle regulation factor,p21~(Cipl/Wafl)on the pathogenesis of endometrialcarcinoma and the clinical significance of its expression.
CyclinE-CDK2 complex is the key regulation factor in the G_(1)/S transition of cell cycle,and its activity is regulated by a network involving cytokines,phosphorylation/dephosphorylation modification,the ubiquitin-dependent proteolysis pathway and cyclin-dependent kinase inhibitors(CKIs) and so on.
Cyc linE-CDK2是细胞周期G1/S期的转折中的关键调控因子,其分子活性受各种细胞因子、磷酸化/去磷酸化修饰、泛素介导的蛋白降解途径及细胞周期依赖性蛋白激酶抑制物(cyc lin-dependent k inase in-h ib itor,CK Is)等多种方式构成的精细调控网络调节。
VEGF expression was positively correlated with the expression of OPN and COX-2.Conclusion OPN,COX-2 and VEGF play a role in the pathogenesis of osteosarcoma,OPN and COX-2 are regulatory factors of VEGF expression.
Part ⅠScreening and identification of small molecular non-peptide agonist of parathyroid hormone receptor and calcitonin receptor. Parathyroid Hormone (PTH) and Calcitonin (CT), the most important regulatory factors in bone remodeling, have actions that promotes bone formation and inhibit bone resopsion.
Egrl and NFAT2 are shown to cooperatively control gene expression of the regulatory factor Id3 and recombinase Rag2, whose functions are critical for T-lymphocyte differentiation.
Bax, a mammalian pro-apoptotic member of the Bcl-2 family, has been demonstrated to be a potential regulatory factor for plant secondary metabolite biosynthesis recently.
This review will discuss the biology of the ETS family transcription factor PU.1, with emphasis on its interactions with two members of the Interferon Regulatory Factor (IRF) family, interferon consensus sequence binding protein (ICSBP) and IRF-4.
Concerning surfactin production, there is no indication whether the genetic regulation, involving a quorum-sensing mechanism, overrides other regulation factors promoted by the fermentation conditions.
Another explanation is the high degree of stability among littoral macroalgae-dominated communities with internal biological regulation factors (like grazing) possibly being able to counteract effects.
In China, as a result of economic, environmental and regulation factors, excess sludge treatment and disposal represents a rising challenge for small and mid-scale municipal wastewater treatment plants (WWTPs).
Data supported influences from the accuracy and motion termination factors but not from the interactive torque regulation factor on submovement incidence.
The optimum of the regulation factor was found to be 2/3 at a luminance of 200 abs, i.e., at this point 1/3 of the slight variations in light intensity are compensated.
The data obtained are interpreted in the framework of the concept of "chromosome memory," in the maintenance of which the key role is played bycis-regulatory factors.
The regulatory factors and production organisation of both crafts are remarkably similar and are placed against the agricultural background of a pre-industrial society.
