Platelets are small enucleated cell fragments specialized in the control of hemostasis, but also playing a role angiogenesis, inflammation and immunity. This plasticity demands broad range physiological processes. Platelet functions mediated through variety receptors, concerted action which must be tightly regulated, order to allow specific timely responses different stimuli. Protein phosphoryl...

to determine the extent and the size of the environment pollution with heavy metals, biologicalmethods, investigating the enzymatic activity of soil can be applied. most frequently, the enzymes investigated in the soils threatened with anthropogenic contamination are phosphatases, dehydrogenases as reacting fastest to the increase in the content of heavy metals in the environment. the aim of th...

in this study cellular phosphatase activity, referred to as enzyme developed color (edc) assay, was used for an in vitro assessment of cell proliferation and cytotoxicity. optimum conditions were established and found to be 10 x103 cells / well at 37°c and 60 min incubation (for developing color). under the same conditions a direct correlation between optical density (00) and cell number was ob...

this study was conducted to evaluate histochemical alterations of river buffalo’s uterine wall acid andalkaline phosphatases (alp and acp), lipase and carbohydrate ratio during follicular and luteal phases.forty apparently healthy and non pregnant river buffalos were considered for removal of the uterus aftersacrifice in slaughterhouse. all dissected uteri were divided into two luteal (by obser...

The objective of this research is to identify Arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. Multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (PAPs). Specific primers were degenerated and designed based on conserved sequences of PAPs isol...

Protein phosphorylation and dephosphorylation are two essential vital cellular mechanisms that regulate many receptors enzymes through kinases phosphatases. Ca2+- dependent phosphatases responsible for controlling neuronal processing; balance is achieved opposition. During molecular of learning memory, generally modulate positively while negatively. This review outlines some the critical physio...

Abstract Receptor‐type protein tyrosine phosphatases (RPTPs), Class I phosphatases, are involved in human tumor cell proliferation, apoptosis, migration, and invasion through reversible phosphorylation of residues. This review summarizes the expression role RPTPs cancer illustrates signaling pathway mechanisms effecting oncogenesis, progression, prognosis, angiogenesis, so as to provide more ef...

it is now well established that the type la of serine/threonine protein phosphatases (pp1α) may be implicated in malignant phenotype. although the pp1α mrna level increased in livers at preneo-plastic stages of hepatocarinogenesis and all of examined rat ascites hepatomas, unexpectedly, dra-matically decreased in some of primary hepatomas. in order to elucidate the low level of pp1α mrna in som...
