The small GTPase R-RAS2 regulates homeostatic proliferation and survival of T and B lymphocytes and, when present in high amounts, drives the development of B cell chronic lymphocytic leukemia. In normal and leukemic lymphocytes, R-RAS2 constitutively binds to antigen receptors through their immunoreceptor tyrosine-based activation motifs (ITAMs) and promotes tonic activation of the phosphatidylinositol 3-kinase (PI3K) signaling pathway. Here, we examined the molecular mechanisms underlying this direct interaction and its consequences for R-RAS2 activity.

Azerbaijan is major producer of fruit crops, such as pome and stone fruits, in the Caspian Sea and Caucasus Mountains areas (FAO Stat, 2022). No information is available on the occurrence of apple chlorotic leaf spot virus (ACLSV, genus Trichovirus, family Betaflexiviridae) in the country. Therefore, the main fruit tree production areas in Azerbaijan were surveyed for ACLSV during the 2017-2019 growing seasons by DAS-ELISA using ACLSV reagents (Neogen - Scotland, UK) (Clark and Adams 1977).

Novel traits in the order Lepidoptera include prolegs in the abdomen of larvae, scales, and eyespot and band color patterns in the wings of adults. We review recent work that investigates the developmental origin and diversification of these four traits from a gene-regulatory network (GRN) perspective. While prolegs and eyespots appear to derive from distinct ancestral GRNs co-opted to novel body regions, scales derive from in situ modifications of a sensory bristle GRN.
