Transcription factor Ascl2 promotes germinal center B cell responses by directly regulating AID transcription.

Cell Rep

June 2021

Institute for Immunology and School of Medicine, Tsinghua University, Beijing, China; Beijing Key Lab for Immunological Research on Chronic Diseases, Beijing 100084, China. Electronic address:

During germinal center (GC) reactions, activated B cells undergo clonal expansion and functional maturation to produce high-affinity antibodies and differentiate into plasma and memory cells, accompanied with class-switching recombination (CSR) and somatic hypermutation (SHM). Activation-induced cytidine deaminase (AID) is responsible for both CSR and SHM in GC B cells. Transcriptional mechanisms underlying AID regulation and GC B cell reactions are still not well understood.

The Rab7 effector WDR91 promotes autophagy-lysosome degradation in neurons by regulating lysosome fusion.

J Cell Biol

August 2021

State Key Laboratory of Conservation and Utilization of Bio-Resources in Yunnan and Center for Life Science, School of Life Sciences, Yunnan University, Kunming, China.

The effectors of the Rab7 small GTPase play multiple roles in Rab7-dependent endosome-lysosome and autophagy-lysosome pathways. However, it is largely unknown how distinct Rab7 effectors coordinate to maintain the homeostasis of late endosomes and lysosomes to ensure appropriate endolysosomal and autolysosomal degradation. Here we report that WDR91, a Rab7 effector required for early-to-late endosome conversion, is essential for lysosome function and homeostasis.

Chrom-Lasso: a lasso regression-based model to detect functional interactions using Hi-C data.

Brief Bioinform

November 2021

School of Medicine and the Tsinghua-Peking Center for Life science, Tsinghua University, Beijing, China.

Hi-C is a genome-wide assay based on Chromosome Conformation Capture and high-throughput sequencing to decipher 3D chromatin organization in the nucleus. However, computational methods to detect functional interactions utilizing Hi-C data face challenges including the correction for various sources of biases and the identification of functional interactions with low counts of interacting fragments. We present Chrom-Lasso, a lasso linear regression model that removes complex biases assumption-free and identifies functional interacting loci with increased power by combining information of local reads distribution surrounding the area of interest.
