Phototherapy, including photodynamic therapy(PDT) and photothermal therapy (PTT), is a promisingmethod of tumor treatment, which has the advantages ofstrong specificity and small side effects. However, PDT willaggravate the hypoxic environment in tumor cells, and PTTwill lead to heat-resistant reaction, both of which will make theorganism quickly produce heat shock proteins (HSPs) toprotect itself, thus seriously hindering the therapeuticefficiency of phototherapy. As a natural HSPs inhibitor,quercetin (QR) provides a feasible way to solve this ***, a kind of metal organic framework (MOF), Fe-TCPP(FT), was used as a delivery material and photosensitizer tobuild a chemo-phototherapy platform, and QR was used as achemotherapy drug and HSPs inhibitor. On this basis, the nanoparticles (NPs) were modified with PEG-CPP30 (a cellpenetratingpeptide that specifically recognizes human breast cancer MCF-7 cells), which showed excellent targetingcapacity and biocompatibility. The combination of chemotherapy and phototherapy significantly improved the anti-cancereffect. At the same time, NPs also showed prominent anti-HSPs effect. The effective connection of the two played acomplementary role in the process of tumor treatment, which provided a new strategy for the accurate and efficienttreatment of tumors in the future.

The identification and clarification of active sites of MoS_(2)have long been the focus of research efforts in hydrogen evolution reaction(HER).In this study,we constructed phase transition-induced 1T-2H MoS_(2)heterojunction via lithium intercalation and evaluated the HER activity using on-chip electrocatalytic microdevices(OCEMs).The heterojunction achieved an overpotential of only 226 mV at a cathodic current density of 10 mA/cm^(2),outperforming the basal planes of 1T and 2H MoS_(2).Furthermore,density functional theory(DFT)calculations demonstrated that the charge redistribution occurs at the 1T-2H MoS_(2)interface with electrons transferring from 1T to 2H MoS_(2),and the interfacial S atom at the top site of 1T MoS_(2)presents the smallest overpotential of 0.37 ***,the interference from highly active edge sites was avoided by precisely exposing specific active areas,quantitatively revealing the catalytic activity order of different types of in-plane MoS_(2)active *** work enables a systematic investigation of the HER activity of various active sites in MoS_(2),laying the foundation for quantitative analysis of activity in other lowdimensional materials.

Fatty alcohol biosynthesis by oleaginous microbes was a promising alternative to the petroleum or other non-renewable resources-based process. However, low titer and yield hamper the further industrial and commercial applications. Here, we developed an efficient strategy to coordinate fatty alcohol with glycolysis which achieved a ‘pull-and-push’ effect to improve fatty alcohol production. Transcript profiling indicated that genes in carbohydrate metabolism were up-regulated significantly in response to high fatty alcohol production. Based on it, 11 glycolysis promoters were screening to express fatty acyl-CoA reductase(FAR) to relate the fatty alcohol production with the up-regulated carbohydrate metabolism, and the fatty alcohol production reached 557 mg/L when FAR was expressed by the promoter of PFBAin. RNA-seq and qRT-PCR analysis demonstrated that a ‘pull-and-push’ effect caused by the coordination system dynamically enhanced the product synthesis flux from top to bottom, which was also testified and intensified by doubled glucose concentration. After manipulating structural and regulatory genes of lipid metabolism, the final strain achieved up to 5.75 g/L fatty alcohol production from modified YPD medium(containing 91 g/L glucose) in shake flasks, which represented the highest titer reported to date. This work offered a feasible and effective reference for dynamic manipulation of fatty acid-derived chemicals synthesis.
