Benchmarking copy number aberrations inference tools using single-cell multi-omics datasets.

Copy number alterations (CNAs) are an important type of genomic variation which play a crucial role in the initiation and progression of cancer. With the explosion of single-cell RNA sequencing (scRNA-seq), several computational methods have been developed to infer CNAs from scRNA-seq studies. However, to date, no independent studies have comprehensively benchmarked their performance.

Role of malate dehydrogenase 1 and isocitrate dehydrogenase 1 and their posttranslational modifications in diseases.

Malate dehydrogenase 1 (MDH1) and isocitrate dehydrogenase 1 (IDH1) are two crucial enzymes in the process of energy metabolism. MDH1 plays a crucial role in the malate-aspartate shuttle in the cytoplasm by utilizing the coenzyme NAD/NADH to catalyze the interconversion of malate and oxaloacetate. IDH1 utilizes the coenzyme NADP/NADPH to facilitate the reciprocal transformation between isocitrate and α-ketoglutarate and plays a significant role in the metabolic processes of carbohydrates, lipids, and proteins in the liver.
