Rice tungro disease is caused by the combined action of Rice tungro bacilliform virus (RTBV) and Rice tungro spherical virus (RTSV). The RTBV is involved in the development of symptoms while RTSV is essential for virus transmission. We attempted to study the mode of action of RTBV in the development of symptoms.

Background: Gastric cancer (GC) is the third most common cancer in India and is mediated by multiple genetic, epigenetic and environmental risk factors. A single nucleotide polymorphism rs3025058 at -1171 of the stromelysin-1 (matrix metalloproteinase [MMP]-3) promoter is resulting due to insertion/deletion of adenine thought to have an impact on increasing the risk for tumor formation.

Aim: This study is aimed to understand the role of stromelysin-1 rs3025058 (-1171, 5A/6A) promoter polymorphism in the etiology of GC in Indian population.

Background: Gastric cancer (GC) is the fifth most common malignancy and remains a considerable public health burden worldwide. Genetic variations in genes encoding cytokines and their receptors influence the intensity of the Helicobacter pylori associated inflammatory response, which may contribute to individual differences in the outcome and severity of the disease. Interleukin4 is a typical pleiotropic T helper 2 (Th2) cytokine and is a critical mediator of Th1/Th2 balance.

Aim: To investigate the role of endothelial nitric oxide synthase -786T > C promoter polymorphism in the etiology of gastric cancer (GC).

Methods: A total of 150 GC patients and 150 control subjects were included in the study. The information on demographic features was elicited with an informed consent from all the patients and control subjects using a structured questionnaire.

In this study, complete genome of a south Indian isolate of Rice tungro spherical virus (RTSV) from Andhra Pradesh (AP) was sequenced, and the predicted amino acid sequence was analysed. The RTSV RNA genome consists of 12,171 nt without the poly(A) tail, encoding a putative typical polyprotein of 3,470 amino acids. Furthermore, cleavage sites and sequence motifs of the polyprotein were predicted.
