Mir223 restrains autophagy and promotes CNS inflammation by targeting ATG16L1.

Microglia are innate immune cells in the central nervous system (CNS), that supplies neurons with key factors for executing autophagosomal/lysosomal functions. Macroautophagy/autophagy is a cellular catabolic process that maintains cell balance in response to stress-related stimulation. Abnormal autophagy occurs with many pathologies, such as cancer, and autoimmune and neurodegenerative diseases.

Apolipoprotein AI-CIII-AIV gene cluster polymorphisms in relation to cholesterol gallstone.

Objective: To investigate the frequency of variants at Xmn I, Msp I sites of apolipoprotein (Apo), A I-CIII-AIV gene cluster, and its relation to cholesterol gallstones in Chinese patients.

Methods: Restriction fragment length polymorphisms (RFLP) at Xmn I, Msp I sites of ApoAI-CIII-AIV gene cluster were studied using a polymerase chain reaction (PCR) in 161 patients with cholesterol gallstones and 94 healthy subjects from a Chinese population in Sichuan Province.

Results: In both the cholesterol gallstone group and the healthy control group, X1 and M1 alleles were the major alleles and homozygous X1X1 and M1M1 genotypes were the most frequent.
