Caco-2 cells were cultivated in glucose-repletion versus glucose-depletion conditions. Quantitative real-time PCR and western blot were performed to assess mRNA and protein levels of different transporters. The amount of 25-NBD cholesterol uptake and the activity of P-gp (ABCB1) protein were measured by direct fluorometry and Rhodamine 123 efflux assay, respectively. Glucose-depleted Caco-2 cells showed lower NPC1L1 expression accompanied by reduced cholesterol uptake when compared to glucose-repleted cells. This effect was associated with an increase in the apical secretion of cholesterol compared with the basal secretion. In addition, glucose depletion upregulated both the expression level and activity of ABCB1, an apical pole transporter. However, the expression levels of ABCG5/G8, an apical sterol dimer transporter as well as ABCA1, a basal cholesterol transporter, were unchanged. The knockdown of ABCB1 in Caco-2 cells increased the intracellular accumulation of cholesterol.

Controlling viral infection with people's health and reducing the impact on people's freedom is difficult at present.

We organized the classification, incidence rate and mortality of COVID-19. And we introduced the discovery process of Omicron, health code of four colors, the epidemiological investigation and the policies of government in Hangzhou. This paper discusses various measures taken against Omicron in Hangzhou, China, which are effective methods to deal with such public health emergencies.Conclusions: Hangzhou quickly controlled the epidemic through precise control. As of February 1, Hangzhou had 115 confirmed cases with total population is 12.204 million. The rate of severe and death is 0%. Hangzhou's new model of precise control provides an important reference for the global city's response to COVID-19 and the reduction in losses caused by COVID-19. The COVID-19 Omicron variant outbreak indicates that people will still face unpredictable health risks in the future.

The epithelial-mesenchymal transition (EMT) represents a critical biological process through which tumor cells gain migratory and invasive capabilities. Nilotinib is a selective inhibitor of tyrosine kinases, commonly utilized in the treatment of chronic myeloid leukemia. Prior investigations have demonstrated that the Nilotinib derivative, N-12, exhibits significant antitumor properties. The objective of this study is to elucidate the inhibitory effects of N-12 on the progression of EMT in colon cancer cells. So, the human colon cancer cell line HCT116 and SW480 were selected for experimentation. Initially, assessments of cell proliferation, migration and invasion were conducted utilizing MTT, colony formation, Edu and Transwell assays. Subsequently, the chick embryo chorioallantoic membrane model was employed to evaluate tumor size and its impact on angiogenesis in vivo. Thereafter, HCT116 cells treated with N-12 underwent RNA sequencing for analysis. Finally, the expression levels of EMT markers in colon cancer cells were determined by Western blot analysis. The results showed that N-12 significantly curtails the proliferation, migration, and invasion of colon cancer cells, and concurrently impedes tumor growth in vivo by influencing angiogenesis within the chick embryo chorioallantoic membrane. Furthermore, RNA sequencing and Western blot analyses have elucidated that the antitumor efficacy of N-12 is attributable to the inhibition of the EMT signaling pathway. These results underscore the therapeutic potential of N-12 in the management of colon cancer and delineate its mechanism of action.","PeriodicalId":19343,"journal":{"name":"Nucleosides, Nucleotides & Nucleic Acids","volume":" ","pages":"1-24"},"PeriodicalIF":1.1,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143542812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several variants of MBL2 have been found to be associated with altered serum levels and susceptibility to various chronic diseases. Defects in MBL protein polymerization that result in functional impairments and/or low serum levels may influence genetic susceptibility to type 2 diabetes (T2D) and its complications. Therefore, the present case-control study was conducted to assess the potential association of six MBL2 gene variants and haplotypes with susceptibility to T2D and its complications in Morocco. The MBL2 gene was genotyped by PCR-sequencing for the promoting, non-coding, and coding regions in 435 individuals. Our findings revealed a significant association between the heterozygous CG and homozygous recessive GG genotypes of the variant at position -221 C > G in the MBL2 gene promoter with an increased risk of T2D. Similarly, for +4 C > T in the non-coding region, statistical analysis indicates a strong association with T2D risk, particularly with the heterozygous CT and homozygous recessive TT genotypes. The LYQC haplotype is also found to be associated with T2D risk. Furthermore, the heterozygous CT genotype, and recessive T allele of the variant at position +4 C > T, and heterozygous GA genotype of codon Gly54Asp of the MBL2 gene, are associated with protection against hypertension in T2D patients. However, no association was observed between MBL2 variants and dyslipidemia in T2D patients.

Isoproterenol (ISO), the β1/β2-adrenergic receptor agonist that leads to myocardial stress and mitochondrial damage, is extensively used for in vitro and in vivo studies to test the efficacy of therapeutic strategies in heart failure (HF). This study evaluated the cell morphology, nucleotide concentrations, and mitochondrial function of ISO-treated cardiomyocytes stimulated with the activators of mitochondrial biogenesis and nucleotide precursors. H9c2 rat cardiomyocyte line cells were treated with ISO in the presence of mitochondrial biogenesis stimuli quercetin (Que), rosiglitazone (Ros), S-Nitroso-N-acetyl-DL-penicillamin (SNAP), and NAD+ precursor, nicotinamide riboside (NR). The intracellular concentrations of nucleotides were analyzed using high-performance liquid chromato-graphy, and the Seahorse metabolic flux analyzer determined the mitochondrial function. ISO decreased intracellular ATP concentration in H9c2 cells as compared to control. The treatment with SNAP increased ATP concentration compared to ISO-only treated cells, while Que, Ros, and NR had no effect. NR treatment led to the elevation of intracellular NAD+ concentration, while the treatment with SNAP, Ros, and NR stimulated the mitochondrial respiration in ISO-pretreated H9c2 cells. In conclusion, mitochondrial biogenesis activators consistently improved cardiomyocyte mitochondrial function, but only selected molecules helped to improve ATP or NAD+ concentrations.

The Schiff base ligand (HL=(E)-N-((6-(thiophen-2-yl)pyridin-2-yl)methylene)-1H-benzo[d]imidazol-2-amine)) was synthesized by the reaction of 6-(thiophen-2-yl)pyridine-2-carbaldehyde with 1H-benzimidazole-2-amine.

Both the general genotype distribution of these variants and the observed genotype ratios were examined separately.Results: In the T2DM group, the proportion of individuals with the AA genotype of the AT1R A1166C variant was lower than in the control group, and the proportion of individuals with the AC genotype was higher. There was no significant difference in the genotype distribution between the groups for the ACE I/D variant. There was no significant difference in the genotype distribution of the ACE I/D and ATIR A1166C variants in patients with and without DPN.Conclusion: In the Turkish population, no significant difference was observed in the overall genotype distribution of ACE I/D and AT1R A1166C variants between T2DM patients and healthy individuals, whereas the AC genotype of the AT1R A1166C variant was more frequent in T2DM patients, and the AA genotype was less frequent. For both variants, no significant difference was observed in the genotype distribution between T2DM patients with and without DPN.","PeriodicalId":19343,"journal":{"name":"Nucleosides, Nucleotides & Nucleic Acids","volume":" ","pages":"1-10"},"PeriodicalIF":1.1,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143007835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
