Notes

RESULTS: Our results showed significantly higher rates of DNA fragmentation, protamine deficiency, and abnormal chromatin condensation in the spermatozoa of hookah smokers (P < 
0001). Also, protamine gene expression showed a remarkable decrease in hookah smokers (55 ± 54 and 33 ± 54) compared to statistically significant (P = .155 and P = .066, respectively). Moreover, a significantly higher level of semen MDA was observed in the case group compared to the controls (39 ± 04 vs 15 ± 21; P = .013).

CONCLUSION: According to our study, although hookah smoking does not have a significant effect on sperm parameters, it may have deleterious effects on DNA integrity, oxidative status, and nuclear protein levels of spermatozoa. cancer driver genes from transposon mutagenesis screens. Transposon screens are powerful in vivo assays used to identify loci driving carcinogenesis. These loci are identified as Common Insertion Sites (CISs), i.e. regions with more transposon insertions than expected by chance. However, the identification of CISs is affected by biases in the insertion behaviour of transposon systems.

Here, we introduce Transmicron, a novel method that differs from previous methods by (i) modelling neutral insertion rates based on chromatin accessibility, transcriptional activity and sequence context and (ii) estimating oncogenic selection for each genomic region using Poisson regression to model insertion counts while controlling for neutral insertion rates. To assess the benefits of our approach, we generated a dataset applying two different transposon systems under comparable conditions. Benchmarking for enrichment of known cancer genes showed improved performance of Transmicron against state-of-the-art methods. Modelling neutral insertion rates allowed for better control of false positives and stronger agreement of the results between transposon systems. Moreover, using Poisson regression to consider intra-sample and inter-sample information proved beneficial in small and moderately-sized datasets. Transmicron is open-source and freely available. Overall, this study contributes to the understanding of transposon biology and introduces a novel approach to use this knowledge for discovering cancer driver genes.

Human mitochondria are the vital cell organelle acting as a storehouse of energy generation and diverse regulatory functions. Mitochondrial DNA comprises 93% coding region and 7% non-coding regions, in which the non-coding region hypothesized as responsible for signaling is our specific interest. Here, we explored the unknown functions of mitochondrial non-coding RNAs by studying their respective signaling pathways. We retrieved conserved motifs of interactions from known experimental protein-RNA complexes to model unknown mitochondrial ncRNA sequences. Our results provide the ncRNAs list and show their involvement in four crucial pathways, such as (i) Processing of Capped Intron-Containing Pre-mRNA, (ii) Spliceosome, (iii) Spliceosomal assembly, and (iv) RNA Polymerase II Transcription, respectively. The interactome analysis revealed that the SRSF2 and U2AF2 proteins interact with ncRNAs. Further, we have simulated the selected ncRNA-protein complexes in cell-like environmental conditions and found them stable in terms of energetics.

Through our study, we have identified an apparent interaction of mitochondrial ncRNAs with proteins and their role in critical signaling pathways, providing new insights into mitochondrial ncRNA-dependent gene regulation.Communicated by Ramaswamy H. Sarma. buy fucose : Cystic echinococcosis (CE) is a zoonotic disease caused by the Echinococcus granulosus senso lato (E. granulosus s.l.) larval stages.

Parasite-derived products have been shown to regulate host matrix metalloproteinases (MMPs), contributing to CE pathogenesis and progressive liver fibrosis in intermediate hosts. The current study aimed to investigate the potential role of MMP1, 7, 8, and 13 in E. granulosus s.l-¬induced liver fibrosis. METHODS: Thirty CE patients with active, transitional, or inactive hydatid cysts were enrolled in this study using qRT-PCR to determine the inductive effects of E. granulosus on the expression of MMP-1, MMP-7, MMP-8, and MMP-13 in healthy liver tissue and fibrotic liver tissue. RESULTS: According to the WHO-IWGE classification, patients with functional cysts (CE1 and CE2) had the highest percentage (6%).

MMP-1, MMP-7, MMP-8, and MMP-13 expression levels were significantly higher in fibrotic liver than in normal liver tissue. MMP-13 and MMP-1 had the highest and lowest expression levels among MMPs. Compared to the normal group, the fold change for MMP-13 in the fibrotic group was greater than 12 and had the highest AUC value (AUC= 8283). CONCLUSIONS: Our findings suggest that E. granulosus-derived products might be involved in regulating host MMPs. Thus, MMPs may be considered potential biomarkers for predicting CE prognosis. Because of the non-normal distribution of our patients' CE types, further research, particularly on circulation MMPs, is needed to confirm the potential role of MMPs in CE pathogenesis and to follow up on CE patients.
