The Role of DNA Repair Pathways in Antibody Somatic Hypermutation

In a recent online publication in SCIENCE CHINA Life Sciences, researchers from the laboratory of Leng-Siew Yeap at the Shanghai Institute of Immunology, Shanghai Jiao Tong University School of Medicine published a review article entitled "Molecular Mechanisms of DNA Lesion and Repair During Antibody Somatic Hypermutation". This review comprehensively summarizes the mechanisms involved in the generation of antigen-specific diversified antibodies, with a particular focus on the mechanisms that generate high-frequency point mutations and low-frequency deletions and insertions (indels) in antibody genes.

New CRISPR Method Allows Comprehensive Screening of Cancer Mutations

Tumors can carry mutations in hundreds of different genes, and each of those genes may be mutated in different ways -; some mutations simply replace one DNA nucleotide with another, while others insert or delete larger sections of DNA.

Breakthrough "Gene Silencing" Technology Could Revolutionize the Development of DNAzymes

Researchers from the University of California, Irvine have developed a DNA enzyme – or DNAzyme – that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact.

Effective backup mechanism ensures efficient antimicrobial responses in humans

In the human body, virus particles are identified by pattern recognition receptors (PRRs) either within or on the cell surface. When a receptor is activated, a signaling cascade is initiated, which results in the production and release of signaling molecules like interferons and cytokines.

A 3D explanation of SPOP’s role in cancer

The protein SPOP, which also plays a role in endometrial, uterine, and other cancers, is the most mutated in prostate cancer. Despite its significance, it is still unclear how SPOP mutations cause cancer.

Enzymes hold the answer to understanding how DNA mutates

According to recent research from the University of Surrey, enzymes, which are essential for regulating how cells replicate in the human body, could be the very component that encourages DNA to spontaneously mutate, leading to potentially permanent genetic errors.

New technique to hunt down mutations that cause cancer drug resistance

Using a virus to purposely mutate genes that produce cancer-driving proteins could shed light on the resistance that inevitably develops to cancer drugs that target them, a new study led by UT Southwestern scientists suggests.

Research reveals fundamental insights into the causes of severe birth defects

Research by Kai Jiao, M.D., Ph.D., and colleagues at the University of Alabama at Birmingham and in Germany has yielded fundamental insights into the causes of severe birth defects known as CHARGE syndrome cases. These congenital birth defects include severe and life-threatening heart malformations.
