However, abiotic stresses such as drought stress severely limit the growth and development of P. bournei, and even lead to its death. It has been shown that basic helix-loop-helix (bHLH) as the second largest transcription factor family plays essential roles in response to multiple stresses in plants. However, little information of bHLH family is available in P. bournei. In this study, 130 PbbHLHs were identified and classified into 24 subfamilies. Then, the bHLH domain, conserved motifs and gene structures, evolutionary patterns and protein structural features were probed. The expression levels of 17 PbbHLHs were differentially induced by PEG and ABA by RT-qPCR analysis, indicating that they may be involved in drought stress response. Characterization of the drought candidate gene PbbHLH74 showed that it was transcriptionally active and localized in the nucleus. Heterologous transformation of PbbHLH74 into yeast improved cellular tolerance to drought stress. Meanwhile, overexpression of PbbHLH74 in Arabidopsis showed higher seed germination, plant biomass and expression levels of stress-related genes under drought conditions. Through the hairy root technique, overexpression of PbbHLH74 in P. bournei improved drought tolerance by enhancing root development and expression levels of genes involved in ABA-dependent and ROS scavenging pathways. Moreover, PbbHLH74 might positively regulate the expression of PbPOD by Y1H and dual-luciferase reporter assays. Overall, these results elucidated the structure and evolution of the PbbHLH family, in which PbbHLH74 could be applied to molecular assisted breeding for drought tolerance in P. bournei.","PeriodicalId":333,"journal":{"name":"International Journal of Biological Macromolecules","volume":" ","pages":"137760"},"PeriodicalIF":7.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, cutinase-catalyzed green hydrolysis of WPET was achieved. The main purpose of this paper is to study the difference between two PEG-free WPETs with different -SO3- content in the cutinase-catalyzed hydrolysis process. Differences in solution properties, enzyme activity, SSIPA, and TPA release as well as functional groups and thermal properties of the hydrolysis products of the systems during cutinase hydrolysis were analyzed in detail for 14.1 % S-0 % PEG and 9.5 % S-0 % PEG. Results show that the structure of WPET has an influential effect on its hydrolysis rate in cutinase-catalyzed systems, which mainly originates from the -SO3- content. SSIPA released by WPET during hydrolysis has an inhibitory effect on cutinase enzyme activity. The hydrolysis process of WPET with higher -SO3- content releases more SSIPA, which in turn inhibits the enzyme activity of cutinase in the reaction system, ultimately leading to a slower hydrolysis rate of WPET. These findings provide new ideas for cutinase to target WPETs with different structures and are important for the green development of the textile industry.","PeriodicalId":333,"journal":{"name":"International Journal of Biological Macromolecules","volume":" ","pages":"137775"},"PeriodicalIF":7.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of Imperata cylindrica polysaccharide (ICPC-a) were explored using a hyperuricemia mouse model and a uric acid-induced HepG2 hepatocyte model. ICPC-a significantly improved total cholesterol, triglycerides, low-density lipoprotein levels, and hepatic lipid deposition in hyperuricemia mice. The liver/body weight ratio decreased, and markers of liver damage, inflammation, and dyslipidemia improved. Metabolomics analysis suggested that ICPC-a modulates lipid metabolism by influencing the glycerophospholipid pathway and the enzyme LPCAT3. Stable HepG2 cell lines with knocked-down LPCAT3 were constructed, and Western blot and RT-PCR were used to assess the impact of its knockdown on lipid metabolism under uric acid stimulation. In cells with reduced LPCAT3 expression, ICPC-a was still able to alleviate uric acid-induced lipid accumulation, though the effect was less pronounced compared to cells with normal LPCAT3 levels. However, the effectiveness was diminished compared to cells where LPCAT3 was not knocked down. These findings indicated that LPCAT3 was an important target through which ICPC-a regulated lipid metabolism disorders induced by hyperuricemia. These discoveries emphasized that ICPC-a, as a prebiotic, could modulate hepatic lipid accumulation and inflammation, contributing to the maintenance of hepatic lipid homeostasis.","PeriodicalId":333,"journal":{"name":"International Journal of Biological Macromolecules","volume":" ","pages":"137592"},"PeriodicalIF":7.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As one of the 26 HCMV miRNAs, hcmv-miR-US33-5p has been reported to inhibit viral DNA synthesis and DNA replication via downregulation of the host gene syntaxin 3. Here, we tested the luciferase activity of 8 other putative target mRNAs of hcmv-miR-US33-5p, which were identified via hybrid PCR, 7 of which decreased following the over expression of hcmv-miRNA-US33-5p. A viral gene, HCMV UL16, was confirmed to be a direct target of hcmv-miR-US33-5p since both luciferase activity and protein levels were decreased by hcmv-miR-US33-5p overexpression. Moreover, by using a reconstituted virus with UL16 deletion, we found that UL16 is not an essential gene for the ability of hcmv-miR-US33-5p to downregulate DNA replication. UL16 plays a critical role in NK cell evasion by sequestering NKG2D ligands in the endoplasmic reticulum (ER) and reducing their cell surface expression. We demonstrated that over expression of hcmv-miR-US33-5p induced some NKG2D ligands independent of other HCMV genes and decreased the interaction between MICB and UL16. These stimulating NKG2D ligands can be recognized by NKG2D and subsequently activate NK cells.
