The rats were fed a diet cooked-fried in such oil. The biomarkers of genotoxicity, comet assay, micronucleus test, and chromosomal aberrations in peripheral blood lymphocytes (PBL) of Wistar rats were used. Results of the present investigation reveal that rats fed on food cooked in oil that was 5 times repeatedly boiled induced significant Deoxy ribonucleic acid (DNA) damage in PBL and liver homogenate. Increased frequency of micronuclei and chromosomal aberrations in blood and bone marrow of rats were also observed. A similar observation was found in rats that were fed food cooked in oil that was boiled 3 times. However, the results of genotoxicity in rats that ate food cooked in oil heated only once were not statistically significant in comparison to the control rats that fed on food made in heated oil (not boiled). Intake of food cooked in repeatedly heated oil of different heating grades induced significant genotoxicity in rats evident by increased DNA damage and frequency of micronuclei and chromosomal aberrations. The presence of PAHs in heated oils triggers the generation of free radicals which could be the possible causative factor for the induced genetic damage.

Consequently, we determined the complete mitochondrial DNA sequence for N. grandis. The circular genome spans a length of 15,344 bp and exhibits a gene composition analogous to that observed in other metazoans, encompassing a comprehensive set of 37 genes. Additionally, the genome features an AT-rich region. The rRNAs exhibited the highest AT content among the 37 genes (70.41%), followed by tRNAs (67.42%) and protein-coding genes (PCGs) (62.76%). The absence of a dihydrouracil arm in trnS1 prevented the formation of the canonical cloverleaf secondary structure. Selective pressure analysis indicated that the PCGs underwent purifying selection. The Ka/Ks ratios for cox1, cox2, cox3, and cob were considerably lower compared to other PCGs, implying strong purifying selection acting upon these particular genes. The mitochondrial gene order in N. grandis was consistent with the reported order in ancestral Pleocyemata. Phylogenetic revealed that N. grandis forms a cluster with the genus Metanephrops, and this cluster further groups with Homarus and the genus Nephrops within the Nephropidae family.

The purpose of this study was to explore the specific mechanism of WTAP in asthma progression, and clarify the intricate interplay between m6A modifications, WTAP, AXIN1, and their collective impact on airway smooth muscle cells (ASMCs) proliferation in asthma. Platelet-derived growth factor-BB (PDGF-BB)-treated ASMCs were used to establish an asthma model in vitro. The cell phenotype was tested using CCK-8, transwell, and wound healing assays. The expression of the Wnt signalling pathway was detected by western blotting. In addition, the relationship between WTAP/YTDHF2 and AXIN1 was assessed by a double luciferase reporter assay. Actinomycin D treatment and RT‒qPCR assays were performed to determine the mRNA stability of AXIN1. We found that WTAP was significantly increased in PDGF-BB-treated ASMCs. Knockdown of WTAP inhibited the excessive cell viability and migration of ASMCs induced by PDGF-BB. Furthermore, WTAP knockdown increased AXIN1 levels and inhibited the Wnt signalling pathway. Furthermore, WTAP knockdown decreased the m6A levels and enhanced the mRNA stability of AXIN1. WTAP overexpression showed the opposite effect. In addition, YTHDF2 was demonstrated to be the reader that recognizes the WTAP-mediated m6A modification of AXIN1. YTHDF2 knockdown enhanced the mRNA stability of AXIN1 and reversed the effect of WTAP overexpression on PDGF-BB-treated ASMCs. WTAP knockdown inhibited the excessive cell viability and migration of ASMCs by enhancing the m6A levels of AXIN1, which was further recognized by YTHDF2. The upregulation of AXIN1 mediated by the WTAP/YTHDF2 axis further inhibited the Wnt signalling pathway. Our study provides a new method for the treatment of asthma.

The mRNA and protein levels of APEX1 and zinc finger CCHC domain containing 9 (ZCCHC9) in blood specimens of AMI patients and normal controls were determined by RT-qPCR and Western blot assays, respectively. H9c2 cardiomyocytes were treated with angiotensin II (Ang II) to induce cardiomyocyte injury and then transfected with small interfering RNA against APEX1 (si-APEX1) or overexpression plasmids of ZCCHC9 (pcDNA-ZCCHC9). The cell viability, apoptosis, inflammatory cytokine levels, and fibrosis-associated protein expression in H9c2 cells were evaluated. ZCCHC9 promoter methylation were detected with methylation-specific PCR (MSP) assay. Then, rescue experiments were performed to explore whether APEX1 mediated cardiomyocyte functions by regulating ZCCHC9 expression. Furthermore, we explored whether the APEX1/ZCCHC9 axis regulated cardiomyocyte injury in AMI via the p38 MAPK signaling pathway. Additionally, an AMI rat model was established using the left anterior descending artery (LAD) ligation method and multipoint intramyocardial injection (5 points, 2 µL/point) of lentivirus (1 × 10⁹ TU/mL) carrying scramble or si-APEX1 was conducted before modeling.

APEX1 knockdown or ZCCHC9 overexpression attenuated Ang II-induced viability reduction, apoptosis, inflammation, and fibrosis in cardiomyocytes. APEX1 inhibited ZCCHC9 expression by promoting DNA methyltransferase 1 (DNMT1)-mediated ZCCHC9 promoter methylation.

Thirty-one ZmCOMT genes were identified in the maize genome, which were distributed across eight chromosomes and mainly clustered on chromosome 4. Most ZmCOMT proteins were predicted to localize in the cytoplasm. Ten different conserved motifs were present in most ZmCOMT proteins, and motif1, motif6, and motif7 were highly conserved and present in all ZmCOMT proteins. The photoresponsivity elements were conserved among all members, and ZmCOMT22 and ZmCOMT10 genes responsive to light. This result suggests a potential function for these two genes in lignin biosynthesis which a previous study had linked to light regulation. Jasmonic acid responsive and abscisic acid cis-acting elements were present in the promoter regions of family members, thus the family may be regulated by hormone signaling pathways of maize. In summary, ZmCOMT genes are ancient, and the highly conserved motifs may be significant in survival and evolution of maize.

Our study aimed to explore TCF21/ABCA10 axis resistance to DDP therapy in ovarian cancer based on regulating mitochondrial cholesterol efflux. Thirty epithelial ovarian cancer tumors and thirty ovarian tissues from non-cancer patients were collected. Western blot and RT-qPCR were used to measure ABCA10 and TCF21 expression levels in these tissues, as well as in a human ovarian epithelial cell line (IOSE-80), OV cells (A2780 and SKOV3), and DDP-resistant OV cell lines (A2780/DDP and SKOV3/DDP). IOSE-80 cells were also infected with ABCA10 knockdown lentivirus to identify the most effective ABCA10 knockdown plasmid. Lentiviral infection was used to create ABCA10 knockdown, ABCA10 overexpression, and TCF21 overexpression anti-DDP OV cell lines. Cell proliferation was detected by CCK-8 and EDU staining, flow cytometry for apoptosis, MTT for metabolic activity, calcium-induced Cytochrome C release, and mitochondrial matrix swelling for mitochondrial function and Oil Red O staining for lipid accumulation. Cholesterol metabolism was evaluated by measuring mitochondrial cholesterol and cholesterol efflux. Protein concentration was determined using the BCA method. A dual-luciferase reporter assay confirmed TCF21's interaction with ABCA10. ChIP also verified this interaction. The mRNA level (P &lt; 0.01) and protein level (P &lt; 0.001) of ABCA10 were downregulated in cancer tissues of OV patients relative to normal ovarian tissues. Relative to human ovarian epithelial cells, ABCA10 expression was significantly downregulated in OV cells (P &lt; 0.01) and even more significantly downregulated in DDP-resistant OV cells (P &lt; 0.001). Compared to the group treated solely with DDP, the overexpression of ABCA10 significantly inhibited the proliferation of DDP-resistant OV cells (P &lt; 0.01), markedly reduced the staining intensity of EDU in these cells (P &lt; 0.05), and substantially accelerated apoptosis in DDP-resistant OV cells (P &lt; 0.01).Overexpression of ABCA10 further accelerated Cytochrome C expression and mitochondrial matrix swelling in DDP-resistant OV cells compared to the DDP-alone group (P &lt; 0.01).

However, what NETs-related genes are associated with cervicitis remains to be determined. Transcriptome analysis was performed using samples of exfoliated cervical cells from 15 patients with cervicitis and 15 patients without cervicitis as the control group. First, the intersection of differentially expressed genes (DEGs) and neutrophil extracellular trap-related genes (NETRGs) were taken to obtain genes, followed by functional enrichment analysis. We obtained hub genes through two machine learning algorithms. We then performed Artificial Neural Network (ANN) and nomogram construction, confusion matrix, receiver operating characteristic (ROC), gene set enrichment analysis (GSEA), and immune cell infiltration analysis. Moreover, we constructed ceRNA network, mRNA-transcription factor (TF) network, and hub genes-drug network. We obtained 19 intersecting genes by intersecting 1398 DEGs and 136 NETRGs. 5 hub genes were obtained through 2 machine learning algorithms, namely PKM, ATG7, CTSG, RIPK3, and ENO1. Confusion matrix and ROC curve evaluation ANN model showed high accuracy and stability. A nomogram containing the 5 hub genes was established to assess the disease rate in patients. The correlation analysis revealed that the expression of ATG7 was synergistic with RIPK3. The GSEA showed that most of the hub genes were related to ECM receptor interactions. It was predicted that the ceRNA network contained 2 hub genes, 3 targeted miRNAs, and 27 targeted lnRNAs, and that 5 mRNAs were regulated by 28 TFs.
