In this study, a conservative noninvasive sampling technique for genetic analyses was developed and optimized in three terrestrial gastropod species, namely, <i>Cornu aspersum</i>, <i>Eobania vermiculata</i>, and <i>Helix lucorum</i>. Our approach involves the sampling of a minimal amount of periosteum and pedal mucus, providing a viable alternative that does not harm the organisms, combining a few modifications in DNA isolation procedures depending on the sample. Mitochondrial CO1 and 18S rRNA genes were successfully amplified from both pedal mucus and periostracum samples, as confirmed by sequencing and BLAST comparisons in GenBank database. Interestingly, among the different sample types, shell from dead individuals demonstrated the highest DNA purity and quantity, likely due to the lack of DNA binding. This nondestructive method provides a promising advancement for conservation genetics, allowing for the study of protected species while maintaining their survival and well-being.

This case-control study, included 195 patients with UC and 250 healthy individuals from the Iranian population. The Multiplex PCR method was used to detect the 7436-bp mtDNA deletion.

Real-time quantitative polymerase chain reaction was used to detect miR-103 expressions in ESCC tissues and cells.

Targeting chromatin modulators to normalize these epigenetic markers is a promising avenue for overcoming cancer drug resistance and improving treatment efficacy. Histone chaperones, implicated in cancer due to their imperfect compensatory mechanisms, represent potential targets for epidrugs. To identify these targets, we performed enrichment and network analyses of histone chaperone interactions, both among themselves and with other proteins. This approach provided insights into structure-function relationships. The selective binding of histone chaperones to canonical histones highlights their potential as epidrugs targets. Network analysis of common histone chaperones identified key hub proteins: HSP90AB1, RBBP4, NPM1, DAXX, and SET. These hub proteins, particularly RBBP4, which formed the largest protein cluster was found associated with oncogenesis, suggesting RBBP4 as prime candidates for therapeutic intervention.
