[Construction and development prospect of evaluation indicator system for sustainable utilization of traditional Chinese medicine resources based on DPSIR model].

Traditional Chinese medicine(TCM) resources refer to the total reserves of plants, animals, and minerals that can be used as raw materials of TCM(including Chinese medicial materials, TCM decoction pieces, TCM dispensing granules, traditional Chinese patent medicine, and TCM hospital preparation) and folk herbal medicine, which served as the material basis of inheritance, innovation, and development of TCM. In recent years, the sustainable utilization of TCM resources has received high attention and acquired a series of significant achievements in resource survey, quality evaluation, resource protection, innovative technology, and development and utilization, which effectively promoted the sustainable utilization of TCM resources and high-quality development of the TCM industry. The most urgent issue currently is to shift the focus of the research on the sustainable utilization of TCM resources from a sustainable utilization technology system to a sustainable utilization evaluation indicator system.

Determination of the chromosomal position effects for plug-and-play application in the chassis cells.

The chromosomal position effect can significantly affect the transgene expression, which may provide an efficient strategy for the inauguration of alien genes in new hosts, but has been less explored rationally. The bacterium harbors a large circular high-GC genome, and the position effect in this chassis may result in a thousand-fold expression variation of alien natural products. In this study, we conducted transposon insertion at TA sites on the genome, and used enrichment and dilution indexes to respectively appraise high and low expression potentials of alien genes at insertion sites.

A positive feedback inhibition of isocitrate dehydrogenase 3β on paired-box gene 6 promotes Alzheimer-like pathology.

Impaired brain glucose metabolism is an early indicator of Alzheimer's disease (AD); however, the fundamental mechanism is unknown. In this study, we found a substantial decline in isocitrate dehydrogenase 3β (IDH3β) levels, a critical tricarboxylic acid cycle enzyme, in AD patients and AD-transgenic mice's brains. Further investigations demonstrated that the knockdown of IDH3β induced oxidation-phosphorylation uncoupling, leading to reduced energy metabolism and lactate accumulation.

Acetylated tau exacerbates apoptosis by disturbing mitochondrial dynamics in HEK293 cells.

An increase in tau acetylation at K274 and K281 and abnormal mitochondrial dynamics have been observed in the brains of Alzheimer's disease (AD) patients. Here, we constructed three types of tau plasmids, TauKQ (acetylated tau mutant, by mutating its K274/K281 into glutamine to mimic disease-associated lysine acetylation), TauKR (non-acetylated tau mutant, by mutating its K274/K281 into arginine), and TauWT (wild-type human full-length tau). By transfecting these tau plasmids in HEK293 cells, we found that TauWT and TauKR induced mitochondrial fusion by increasing the level of mitochondrial fusion proteins.
