Chronic lymphocytic leukemia(CLL)is a mature B-lymphocyte proliferative tumor with significant heterogeneity.Studies have demonstrated that aberrant activation of the B-cell receptor(BCR)signaling pathway repre-sents the central mechanism underlying CLL.In recent years,inhibitors targeting the BCR signaling pathway have marked-ly improved the prognosis of patients with CLL.This review summarizes the specific roles and clinical applications of the BCR and its associated signaling pathways in CLL pathogenesis,describes how BCR modulates the tumor microenviron-ment,and delineates the metabolic reprogramming mediated by BCR signaling.

The chloroplast genome encodes many key proteins involved in photosynthesis and other metabolic processes, and metabolites synthesized in chloroplasts are essential for normal plant growth and development. Root-UVB (ultraviolet radiation B)-sensitive (RUS) family proteins composed of highly conserved DUF647 domain belong to chloroplast proteins. They play an important role in the regulation of various life activities such as plant morphogenesis, material transport and energy metabolism. This article summarizes the recent advances of the RUS family proteins in the growth and development of plants such as embryonic development, photomorphological construction, VB6 homeostasis, auxin transport and anther development, with the aim to facilitate further study of its molecular regulation mechanism in plant growth and development.
