AI Article Synopsis
- A heminested PCR assay was developed to assess the quality of genomic DNA from various animal species, focusing on the highly conserved histone H4 gene family.
- The study analyzed tissue samples from 43 species, including both invertebrates and vertebrates, as well as ancient DNA from woolly mammoths, demonstrating a 95% success rate in amplifying DNA from the samples.
- Results indicate that the HIST2H4 amplifiers are effective for DNA quality testing and can assist in identifying different animal species.
Article Abstract
To control the quality of genomic DNA of samples from a wide variety of animals, a heminested PCR assay specifically targeting a nuclear gene has been developed. The histone H4 gene family comprises a small number of genes considered among the most conserved genes in living organisms. Tissue samples from necropsies and from cells belonging to 43 different species were studied, eight samples from invertebrates and 35 samples from vertebrates covering all classes. Ancient DNA samples from three Siberian woolly mammoths (Mammuthus primigenius) dating between 40,000 and 49,000 years before present were also tested for PCR amplification. Performance of HIST2H4 amplification were also compared with those of previously published universal PCRs (28S rRNA, 18S rRNA, and cytochrome b). Overall, 95% of species studied yielded an amplification product, including some old samples from gorilla and chimpanzees. The data indicate that the HIST2H4 amplimers are, thus, suitable for both DNA quality testing as well as species identification in the animal kingdom.

It is believed that aneuploid embryos release cell-free DNA (cfDNA) into the blastocyst cavity during the self-correction process through the apoptotic mechanism. This study aimed to develop less invasive methods for predicting ploidy status by investigating how ploidy status affects blastocoel fluid DNA (BF-DNA) levels and apoptotic gene expression as indicators of embryo viability. Human blastocysts were classified into three groups; Survivable Embryo (SE), Fatal Single and double Aneuploidy (FSDA), and Multiple Aneuploidy (MA) using array comparative genomic hybridization (array-CGH) by trophectoderm (TE) biopsy.

Background: Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE)-mediated membrane fusion is crucial for autophagy, making YKT6, a key modulator of cell membrane fusion, a potential target for cancer therapy. However, its oncogenic role across different cancers remains unclear. This study was to investigate the prognostic value and potential immunological functions of YKT6, including cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC).
