The cardiovascular sarcoplasmic reticulum (SR) calcium (Ca2+) ATPase is an imperative determinant of cardiac functionality. In addition, anomalies in Ca2+ handling protein and atypical energy metabolism are inherent in heart failure (HF). Moreover, Ca2+ overload in SR leads to mitochondrial matrix Ca2+ overload, which can trigger the generation of Reactive Oxygen Species (ROS), culminating in the triggering of the Permeability Transition Pore (PTP) and Cytochrome C release, resulting in apoptosis that leads to arrhythmias and numerous disorders.

The arachidonic acid (AA) metabolic pathway, plays a vital role in the production of eicosanoids by the action of pro-inflammatory secretory phospholipase A (PLA ). Release of eicosanoids is known to be involved in many inflammatory diseases. Identification of the inhibitory molecules of this AA pathway enzyme along with the regulation of intracellular signaling cascades may be a finer choice to develop as a powerful anti-inflammatory drug.

Hemostasis is a proteolytically regulated process that requires activation of platelets and the blood coagulation cascade upon vascular injury. Activated platelets create a thrombogenic environment and amplify the coagulation process. Plant latex proteases (PLPs) have been used as therapeutic components to treat various ailments by folk healers.

Echis carinatus (EC) is known as saw-scaled viper and it is endemic to the Indian subcontinent. Envenoming by EC represents a major cause of snakebite mortality and morbidity in the Indian subcontinent. Zinc (Zn++) dependent snake venom metalloproteases (SVMPs) present in Echis carinatus venom (ECV) is well known to cause systemic hemorrhage and coagulopathy in experimental animals.

Acetamide (CAS 60-35-5) is detected in common foods. Chronic rodent bioassays led to its classification as a group 2B possible human carcinogen due to the induction of liver tumors in rats. We used a toxicogenomics approach in Wistar rats gavaged daily for 7 or 28 days at doses of 300 to 1500 mg/kg/day (mkd) to determine a point of departure (POD) and investigate its mode of action (MoA).

Hemostasis is a tightly regulated process which maintains a fluid state of blood within the vasculature and provides thrombotic response upon tissue injury. Various scientific studies have implicated the role of plant latex proteases in hemostasis using in vitro experiments. However, in vivo models substantiate their role in hemostasis.

Background: In higher primates, although LH/CG play a critical role in the control of corpus luteum (CL) function, the direct effects of progesterone (P4) in the maintenance of CL structure and function are unclear. Several experiments were conducted in the bonnet monkey to examine direct effects of P4 on gene expression changes in the CL, during induced luteolysis and the late luteal phase of natural cycles.

Methods: To identify differentially expressed genes encoding PR, PR binding factors, cofactors and PR downstream signaling target genes, the genome-wide analysis data generated in CL of monkeys after LH/P4 depletion and LH replacement were mined and validated by real-time RT-PCR analysis.
