Cell counting and Luminescent Cell Viability Assay were performed to measure the cell proliferation and viability. Soft-Agar Colony Formation (CFU) assay was conducted to measure the capacity of single cells to form colonies in vitro. Cell apoptosis, cell cycle, and cell differentiation were assessed by flow cytometry. Western blotting and RT-qPCR were utilized to examine AKR1B1 expression in acute leukemia cells.

We explored the AKR1B1 effect and mechanism in acute leukemia cells using RNA-sequencing technology and transcriptomic analysis. AKR1B1 is highly expressed in acute leukemia cells. Knockdown of AKR1B1 inhibited acute leukemia cell proliferation, colony-forming capability, and cell cycle and promoted apoptosis. Additionally, xenograft experiments proved that knockdown of AKR1B1 delayed the progression of acute leukemia cell in vivo. RNA-sequencing data analysis demonstrated that AKR1B1 was involved in the epigenetic silencing of H3K27me3-targeted genes. EZH2 inhibitor UNC1999 combined with knockdown of AKR1B1 showed synergistic inhibitory effect on acute leukemia cells.

To evaluate the in vivo functions of circ_0000972, HCC cells with circ_0000972 overexpression were utilized to establish xenograft model through subcutaneous injection. The cell colony and sphere formation assays were adopted to evaluate the impact of circ_0000972 on the stemness characteristics of HCC cells. Additionally, the interaction between circ_0000972, miR-96-5p, and PFN1 was determined through bioinformatics analysis, dual-luciferase reporter assays, and rescue experiments. Circ_0000972 and PFN1 expression was significantly downregulated in HCC tissues and cells, while miR-96-5p exhibited an increased expression level. The overexpression of circ_0000972 was observed to inhibit the cell colony, sphere formation, and EMT of HCC CSCs. In xenograft model, circ_0000972 overexpression restrained the tumor volume and weight. Mechanistically, circ_0000972 stimulated PFN1 expression through the inhibition of miR-96-5p. More importantly, circ_0000972 overexpression could promote PFN1 expression and inhibit the stemness of HCC CSCs. Interestingly, the effect of circ_0000972 overexpression on such progresses was reversed by PFN1 silencing.

They are a family of less numerous and more varied proteins that form a unique monophyletic group. They play an important role in various abiotic and biotic stress responses through Ca2+-mediated signaling. Chickpea (Cicer arietinum L.) is one of the most widely grown legume crops in the world. In recent years, intensive research has been carried out to identify and elucidate genes and molecular pathways that control stress responses in plants. The availability of the chickpea genome has hastened the functional genomics of chickpea. In the current study, we attempted Genome-wide identification and in silico analysis of Annexins in chickpea. Thirteen annexin sequences have been identified in the chickpea genome. Four conserved annexin domains were found in ten annexin members, while three annexins CaAnn5, CaAnn12, and CaAnn13, showed three, two, and one conserved domain, respectively. The gene structure analysis showed the presence of multiple exons in all thirteen annexins. Most Annexin genes are composed of 3-5 introns. Their chromosomal locations showed that out of thirteen genes, ten could be mapped on four chromosomes. Three genes were placed on the scaffold regions. The promoter sequence analysis of all thirteen annexins showed the presence of various elements related to growth and development and response to different phytohormones and abiotic stress. The gene expression data of different annexins in various tissues like leaf, shoot, root, flower bud, and young pod showed their differential expression. Analysis of expression data of roots in drought stress showed their differential expression with the different stages of plant growth. Overall, the current findings show the possible role of CaAnns in different stages of plant growth and development in normal and stressful conditions. Moreover, these findings will be helpful in the further characterization of CaAnn genes and their promoters.","PeriodicalId":482,"journal":{"name":"Biochemical Genetics","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142765376","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}

The studied variations were genotyped by applying the PCR-RFLP and the tetra-ARMS-PCR reaction) techniques. The effect of variation in lncRNA on miRNA:lncRNA interactions, lncRNA-RNA interaction network, and the impact of the variations on the splicing site were predicted using different computational databases. The codominant heterozygous (TC vs. TT) model, the dominant (TC + CC vs. TT) model, the overdominant (TT + CC vs. TC) model, the C allele of rs2023843, and the C allele of rs55829688 had a protective role against PCOS. The A allele of rs4081134 and G allele of rs7158663 of the MEG3 conferred an increased risk of PCOS by 1.37 and 1.44 folds, respectively. The interaction analysis revealed that TC/GG/AA/TC and TC/GG/GA/TC strongly decreased the risk of PCOS by 94 and 92%, respectively.

Following RNA extraction from sperm samples, reverse transcription and real-time PCR were performed to assess the levels of circular ANKLE2 and circular L3MBTL4 RNA. There was a significant up-regulation of circularANKLE2 RNA expression (p < 0.05), and a significant down-regulation of circularL3MBTL4 RNA expression (p < 0.05) in asthenozoospermia, astheno-teratozoospermia, and oligo-astheno-teratozoospermia groups, as well as, in immature spermatozoa separated from normozoospermic samples. Moreover, the altered expression of both circular L3MBTL4 and circular ANKLE2 RNA showed significant correlations with the associated sperm parameters.

Regulatory B cells (Breg cells) can impair antitumor immunity in patients with OC. The imbalanced serum soluble CD40/CD40L pathway is associated with ovarian tumors. This study aimed to explore the mechanisms involving CD40/CD40L signaling through which Breg cells promote the progression of OC. Breg cells were isolated from peripheral blood samples of 20 patients with OC and 20 healthy controls and identified by flow cytometry. Then, the soluble CD40L concentration in peripheral blood serum of OC patients and healthy volunteers was measured by enzyme-linked immunosorbent assay (ELISA), and we found that the serum soluble CD40L level markedly increased and the proportion of Breg cells was positively correlated with CD40L level in peripheral blood of OC patients. Besides, Breg cells were isolated from spleens of female C57BL/6 WT mice and CD40-/- mice. Reverse transcription-quantitative polymerase chain reaction, cell counting kit-8 assays, colony formation assays, flow cytometry, Western blotting, wound healing assays, and Transwell assays were conducted to assess the in vitro effect of Breg cells and CD40. We found that Breg cells contributed to cell proliferation, migration, and invasion and suppressed cell apoptosis in OC via the CD40/CD40L pathway. Moreover, we established a xenograft tumor model in female nude BALB/c mice. Tumor size and weight were evaluated, and Western blotting and ELISA were conducted, and we found that Breg cells promoted tumor growth via CD40 signaling. In conclusion, this study demonstrates that Breg cells activated by the CD40/CD40L pathway promotes the aggressiveness of OC cells and tumor growth, indicating that targeting the CD40/CD40L pathway might represent a novel therapeutic option for OC treatment.","PeriodicalId":482,"journal":{"name":"Biochemical Genetics","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142685717","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}
