AN EPIGENETIC CLOCK FOR GALLIFORMES

The invention pertains to an in vitro method for predicting the chronological age of healthy Galliformes, the method comprising the steps of: (a.) obtaining genomic DNA from biological sample material deriving from the Galliformes subject or from the Galliformes population to be tested, (b.) determining the methylation level of a set of specific CpG sites in the genomic Galliformes DNA obtained in step (a.), and (c.) comparing the methylation levels of these CpG sites in the genomic Galliformes DNA from the sample to be tested with the methylation level of the same CpG sites from an age-correlated reference sample, thereby establishing the epigenetic age and predicting the chronological age of the subject or of the population to be tested; wherein for the set of specific CpG sites in step (b) the impact of genetic polymorphisms is eliminated by excluding CpG sites associated with single nucleotide polymorphisms, and the impact of sex-specific methylation differences on sex chromosomes is eliminated by excluding all CpG sites located on sex chromosomes.

11643695 · 2023-05-09 · ·

The invention provides a Siniperca chuatsi IL-6 gene and a detection method for a disease-resistant SNP marker. A cDNA sequence of S. chuatsi IL-6 gene is cloned, as shown in SEQ ID NO: 1. A IL-6 gene gDNA sequence containing an intron of the S. chuatsi IL-6 gene is cloned, as shown in SEQ ID NO: 2. A primer for amplifying a disease-resistant SNP locus is designed according to IL-6 gDNA sequence, and S. chuatsi IL-6 gene is amplified to obtain an amplification product which is sequenced, and the SNPs loci relevant to virus disease-resistance are found out and the SNP locus is determined according to DNA peak profile. The IL-6 cDNA full-length sequence and IL-6 gDNA full-length sequence are cloned firstly. The SNP locus relevant to virus disease resistance of S. chuatsi IL-6 gene is detected, thereby providing a new method for breeding of S. chuatsi.

AGE-MODIFIED CELLS AND METHODS FOR MAKING AGE-MODIFIED CELLS

Provided are age-modified cells and method for making age modified cells by reducing or increasing the level of genomic nucleic acid methylation in the cells. The aging and/or maturation process can be accelerated or reduced and controlled for young, aged, mature and/or immature cells, such as a somatic cell, a stem cell, a stem cell-derived somatic cell, including an induced pluripotent stem cell-derived cell, by reducing or increasing the level of genomic nucleic acid methylation in the cells. Methods described by the present disclosure can produce age-appropriate cells from a somatic cell or a stem cell, such as an old cell, young cell, immature cell, and/or a mature cell. Such age-modified cells constitute model systems for the study of late-onset diseases and/or disorders.
