Antiproliferative protein (APP) isolated from conditioned media of two androgen-independent prostatic carcinoma cell lines, PC3 and Du-145 was shown to inhibit selectively cell proliferation of androgen-dependent prostate cancer cell line LNCaP in a dose dependent manner. This protein was further purified with HPLC using hydrophobic interaction column (phenyl 5PW) and was used to study the modu...

Glutamate, as an essential neurotransmitter, has been thought to have different roles in the central nervous system (CNS), including nerve regeneration, synaptogenesis, and neurogenesis. Excessive glutamate causes an up-regulation of the multiple signaling pathways, including phosphoinositide-3 kinase/protein kinase B (PI3K/Akt), Akt/mammalian target of rapamycin (mTOR) protein, mitogen-activat...

The geminivirus protein AL1 initiates viral DNA replication, regulates its own expression, and induces plant gene transcription. To better understand how AL1 interacts with host proteins during these processes, we used yeast two-hybrid library screening and a baculovirus protein interaction system to identify plant proteins that interact with AL1. These studies identified a Ser/Thr kinase, a ki...

patients with diabetes mellitus (dm), experience significant morbidity and mortality from microvascular retinopathy, nephropathy and neuropathy. hyperglycemia can induce diabetic complications through multiple pathways. activation of protein kinase c (pkc) by hyperglycemia is one of the pathways which causes diabetic complications. effect of nifedipine (a calcium channel blocker), and polymyxin...

evidence acquisition the fifty two significant articles discussing the stem cell in chronic myeloid leukemia from 1996 to 2012 were selected according to the authors’ experience. results studies have shown that primitive cml cells are less responsive to tyrosine kinase inhibitors (tkis) and are a reservoir for the relapse of multi drug resistant (mdr). conclusions following that, minimal residu...

sepsis as the host responsive syndrome is one of the main concerning issues and costly disease on intensive care unit (icu) in the 21st century. epidemiological studies have showed that mortality rates of sepsis in icu and hospitals among 37 countries were 39.2% and 49.6% respectively [1].  complicated nature of sepsis is still not well understood and this makes it hard to treat and manage. acc...

Mitogen-activated protein kinase (MAPK) cascades regulate a myriad of plant biological processes, including disease resistance. Plant genomes encode large number MAPK kinases (MAPKKKs) that can be divided into two subfamilies, namely MEKK-like and Raf-like kinases. Thus far, the functions MAPKKKs have been relatively well characterized, but roles in remain less understood. Here, we report role ...

Eukaryotic protein kinases belong to a large superfamily with hundreds to thousands of copies and are components of essentially all cellular functions. The goals of this study are to classify protein kinases from 25 plant species and to assess their evolutionary history in conjunction with consideration of their molecular functions. The protein kinase superfamily has expanded in the flowering p...
