Technical Serial No. 2: Application of Cre-loxP site-specific recombination system in the study of conditioned target gene function in mice
Time of Update: 2021-10-10
1. Influencing factors of Cre non-specific/error recombination/random insertion mutation At present, the commonly used Cre mouse models are mostly constructed by traditional transgenic technology, that is, the so-called cell/tissue-specific promoter partial DNA fragmentation strategy, coupled with random insertion of genes, may produce the so-called gene expression position effect and other characteristics, resulting in Cre expression The inaccuracies or leakage of, it is difficult to truly reflect the real desired specificity, resulting in off-target cleavage of Cre expression .

The Lancet: Cure type 2 diabetes! Metabolic surgery can completely reverse the condition for up to 10 years
Time of Update: 2021-01-29
's previously published results showed that two years after surgery, no patients in the drug treatment group achieved diabetes remission (without medication, HbA1c-lt;6.5% and perititucation blood sugar-lt;5.55 mmol/L lasted at least one year), while 75% of the gastric bypass surgery group and 95% of the bile pancreatic reflow group achieved remission, respectively.
