Abstract

Zona pellucida is one of the protective layer of the egg cell and has a function as an intermediary species-specific fertilization. Glycoproteins of human and bovine zona pellucida is composed of three types, namely ZP1, ZP2 and ZP3. ZP3 gene has amino acid sequence homology with other mammals. Oligosaccharides components of the zona pellucida glycans are composed from units of asparagine residues (N -linked) and serine/threonine (O -linked). The aims of this study was to analyze the DNA sequences of human and bovine and further predicts glycans site on amino acid sequence of human and bovine ZP3. In this study, ZP3 gene fragments have been isolated from bovine and humans were analyzed in Silico. This work were conducted by comparing the data of DNA sequence from human and bovine PCR product using NCBI BLAST. The results showed that there were similarities at amino acid positions number 23-38. bZP3 sequence had three glycans site (Asn-X-Thr/Ser) and one site on hZP3 glycans. One of the sites was conserved between the two species.

Abstract

This paper reports a screening results of the secondary metabolites composed in Spathodea campanulata Beauv stem bark, evaluate inhibiting activity of malondialdehyde (MDA) on rats cancer model exposed with benzopyrene, and the histology of its lung. The secondary metabolite of the stem bark fraction consisted of alkaloids, flavonoids-phenolic, terpenoid and steroid compounds. The isolated fraction contained of these metabolites significantly indicate bioactivity by reducting of malondialdehyde (MDA) level, and also histology appearance of the lung tissue prepared from the benzopyrene-exposed rat indicated a curative activity.

Abstract

Myocardial infarction (MI) is a significant contributor to global morbidity and mortality. The outcome of MI is associated with the inflammatory response triggered by ischemic or necrotic cells. Pyroptosis is a type of programmed cell death that can exacerbate cardiac injury following MI. This study reviewed the potential therapeutic effects of colchicine in regulating cardiac pyroptosis in response to MI. Primarily, colchicine inhibits tubulin polymerization and microtubule formation, disrupting inflammasome advancement and the subsequent secretion of various pro-inflammatory mediators. In particular, colchicine disrupts the NLRP3 inflammasome assembly process by blocking ASC recruitment into the complex, suggesting its potential to mitigate the inflammatory response related to cardiac pyroptosis. Additionally, colchicine binds to P2X7 receptors, reducing ATP-induced microtubule and pore formation, which attenuates reactive oxygen species and IL-1β production. A clinical trial involving colchicine showed positive outcomes in lowering the occurrence of major cardiovascular events in individuals with coronary artery disease (CAD). Nonetheless, additional studies are required to ascertain the ideal dosage, timing, and long-term effects of colchicine in the infarcted myocardium before it can be routinely recommended for post-MI treatment. In conclusion, colchicine's modulation of the inflammatory response and inhibition of pyroptosis highlight its potential as a cardioprotective agent for MI management.
