In tumorigenesis, cancer genetics and the related mutations have been the main topic of study these days. Caspases have been found to be actively involved in the process of apoptosis. Malfunction of apoptosis is one of the causes for cancerous tumors and different caspase mutations are related to that process. It has been found that two groups of caspases involved in this process apoptosis which are initiator caspases and executioner caspases. SNPs have been extensively studied over the last decade, due to their association with a number of genetic diseases. Human SNPs have always been a source of information related to the complex changes associated with their origin. SNPs which can change the resulting amino acid i.e., nonsynonymous SNPs (nsSNPs) are of prime concern these days because of their direct relation with the disease or the respective individual. In this study our focus is not only to detect the nsSNPs available in the human caspase data but to further evaluate the potentially damaging nsSNPs. Using the computational approach we have been able to obtain almost seventy eight nsSNPs, among these few of the nsSNPs seem to have serious consequences, as they have been cross verified from a variety of SNP prediction tools. The functional as well as structural impact of the nsSNPs is determined and discussed. Our predicted nsSNPs on human caspases may be associated with cancer risk.

Urinary tract infections (UTIs) are amongst the most common microbial infections worldwide, with ∼11% of the world's population. Several plants parts are used in traditional healing systems to treat UTIs, yet the therapeutic potential of these plants against bacteria that cause UTI remains poorly explored. Approximately, 153 plant species identified and uses to treat UTIs. Several studies described toxic, carcinogenic, and mutagenic properties for extracts prepared from plants conventionally used as medicines.

Human death receptors (TNFR1, FAS, DR3, DR4, DR5, DR6 and TNFBR), primarily from tumor necrosis receptor super family, play an essential role in the process of the extrinsic pathway of apoptosis. We performed conserved domain, amino acid residues analysis in which cysteine residues were found to be highly conserved for all the family members. Sixteen (16) highly conserved residues were observed in TNFR1, DR3 and TNFBR; and in case of Fas, only seven (7) residues are highly conserved. From molecular phylogenetics, we found that DR5 and DR4, TNFR1 and DR3 and TNFR1 and DR3 had the same point of origin. Alternatively, Fas was found to be distant from the rest of the death receptors. A network map was developed to explain these proteins are not only interlinked among themselves, but also interlinked with several other proteins. We have also observed from this system that scores of all the nodes ranges from 0.996 to 0.999.
