Abstract Although CRISPR-Cas12a [clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 12a] combining pre-amplification technology has the advantage of high sensitivity in biosensing, its generality and specificity are insufficient, which greatly restrains application range. Here, we discovered a new targeting substrate for LbaCas12a (Lachnospiraceae bacterium Cas12a), namely double-stranded DNA (dsDNA) with sticky-end region (PAM−SE+ dsDNA). We that...

The CRISPR-Cas12a system is a new type of genome editing tool with high efficiency and targeting. However, other sequences in the may also be cleaved nonspecifically, resulting unavoidable off-target effects. Therefore, it necessary to learn more about mechanism recognize target avoid its Here, we show that insertion (DNA bubble) or deletion (RNA dsDNA sequence compared crRNA sequence, can still cleave sequence. We conclude tolerance bubbles closely related location size bubble GC base...

In this work, the protective effect of apple polyphenol extract (APE) on hepatic steatosis was investigated. Thirty-two C57BL/6J mice were assigned randomly to control group, lovastatin and APE group. After 8 weeks intervention, supplementation markedly decreased body weight gain, liver weight, index, epididymal adipose serum, lipid levels. Hematoxylin eosin staining revealed that alleviated histopathological changes steatosis. Western blot downregulated protein levels GRP78, IRE1α, p-IRE1α,...
