Lysine lactylation is a recently discovered post-translational modification with emerging roles in both physiology and disease.A recent study published in cell shows that lactate-induced lactylation of the homologous recombination(HR)protein meiotic recombination 11 results in HR hyperactivation and chemoresistance in cancer cells,establishing a previously unrecognized link between cellular metabolism and deoxyribonucleic acid(DNA)damage repair and providing new insights into how altered glucose metabolism can impact DNA damage response in cancer.

In-situ synthesis of quantum dots in the nucleus of live cells

National Science Review 2024年第3期11卷 172-182页

The cell nucleus is the main site for the storage and replication of genetic material, and the synthesis of substances in the nucleus is rhythmic, regular and strictly regulated by physiological processes. However,whether exogenous substances, such as nanoparticles, can be synthesized in situ in the nucleus of live cells has not been reported. Here, we have achieved in-situ synthesis of CdSxSe1-xquantum dots（QDs） in the nucleus by regulation of the glutathione（GSH） metabolic pathway. High enrichment of GSH in the nucleus can be accomplished by the addition of GSH with the help of the Bcl-2 protein. Then, high-valence Se is reduced to low-valence Se by glutathione-reductase-catalyzed GSH, and interacts with the Cd precursor formed through Cd and thiol-rich proteins, eventually generating QDs in the nucleus. Our work contributes to a new understanding of the syntheses of substances in the cell nucleus and will pave the way for the development of advanced ‘supercells’.

cellular senescence, a natural process wherein cells cease division and undergo irreversible growth arrest, has long captivated the curiosity of scientists because of its many implications in aging and disease. Recent research has shed light on the nexus between cellular senescence and malignant transformation, thus leading to a paradigm shift in understanding cancer development and progression.
