abstract phosphoenolpyruvate carboxykinase, encoded by the pepck gene, plays an important role in gluconeogenesis. it also seems to be important in metabolism of nitrogenous compounds in developing seeds of legumes, including amides and ureides which are then transformed into amino acids, necessary for the synthesis of storage proteins. in this research, pepck gene expression in mrna level, in ...

prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...

Background Asthenozoospermia accounts for almost 50% of the cases of male infertility. Our study investigating phosphoproteins differentially expressed in asthenozoosperm has identified the phosphoproteins relevant to sperm motility and the signature molecules likely to be altered in asthenozoospermia. The 66 phosphoproteins differentially expressed included four alpha tubulin isoforms which we...

cyclin e, her-2 and p53, are considered as major prognostic markers in breast cancer. as they are related in patho-clinical level, we aimed to check if they have any direct interaction on expression of each other. to study the effect of cyclin e on her-2 expression, cell lines stably overexpressing cyclin e or its low molecular weight (lmw) isoforms were generated. to understand the results of ...

The objective of this descriptive study was to determine Felis domesticus (cat) and Canis familiaris (dog) protein epitopes that bind strongly to selected HLA class II alleles to identify synthetic vaccine candidate epitopes and to identify individuals/populations who are likely to respond to vaccines. FASTA amino acid sequences of experimentally validated allergenic proteins of house cat and d...

Herein, we assessed the effect of full native peptide amyloid-beta (Aβ) (1-42) and its fragments (25-35 35-25) on tissue transglutaminase (TG2) isoforms (TG2-Long TG2-Short) expression levels olfactory ensheathing cells (OECs). Vimentin glial fibrillary acid protein (GFAP) were also studied. The pre-treatment with indicaxanthin from Opuntia ficus-indica fruit TG2 isoforms, cell viability, total...

Peroxisome proliferator-activated receptors (PPARs), which exert multiple key signaling functions in human skin physiology and pathology, exist various isoforms. These include canonical (cPPARγ1-4) dominant negative isoforms (dnPPARγ: γORF4 (γ1-3ORF4), truncated PPARG (PPARγtr) PPARγΔ5. Yet their exact expression patterns remain unclear. Therefore, we have localized quantified PPARγ biopsies fr...

transforming growth factor betas (tgf?s) are one of the most widespread and versatile cytokines. the three mammalian tgf? isoforms, ?1, ?2, and ?3, and their receptors regulate proliferation of neuronal precursors as well as survival and differentiation in neurons of developing and adult nervous system. functions of tgf?s has a wide spectrum ranging from regulating cell proliferation and differ...

Background: Withania somnifera L. Dunal, (Ashwagandha) belongs to the family Solanaceae and is known as ‘Indian ginseng’ in the traditional system of medicine. Objectives: In the present investigation, comparative analysis was carried out between two different ecotypes of W. somnifera related to total soluble protein and antioxidant enzyme activity [catalase (CAT), s...

The p70 ribosomal S6 kinase (S6K) family is a group of highly conserved kinases in eukaryotes that regulates cell growth, proliferation, and stress response via modulating protein synthesis biogenesis. S6Ks are downstream effectors the Target Rapamycin (TOR) pathway, which connects nutrient energy signaling to growth homeostasis, under normal conditions. plant S6K includes two isoforms, S6K1 S6...
