Alzheimers Dement

Background: Dementia is age-related with a significant genetic contribution, yet genome-wide association studies have not fully accounted for heritability. This discrepancy may in part be due to reliance on SNPs and small indels. Whole-genome sequencing (WGS) data in the Japanese population may reveal population-specific susceptibility loci for dementia.

FLP-FRT, a well-established technique for genome manipulation, and the revolutionary CRISPR/Cas9, known for its targeted indels, are combined in a novel approach. This unique method is applied to the Hox genes in the Drosophila melanogaster bithorax complex, which are closely located to the cis-regulatory modules that define their spatial-temporal regulation. The number and position of these genes are directly correlated to their expression pattern.

is part of the normal flora of the human gut and performs vital functions; however, certain strains can cause disease in the host, impairing gut function and adversely affecting overall health. The pks gene cluster in the B2 serogroup encodes colibactin, a secondary metabolite and a potential gut toxin. However, the mechanism underlying colibactin production in is complex, and the function of the pks gene cluster is not fully understood.

Multi-insertion/deletion polymorphisms (Multi-InDels), as the novel genetic markers, show great potential in forensic research. Whereas, forensic researchers mainly focus on the multi-InDels on the autosomes, which can provide relatively limited information in some complex paternity cases. In this study, a novel X chromosomal multi-InDel multiplex amplification system was designed, containing 22 multi-InDels and one STR locus on the X chromosome.

This study reports a novel porcupine model exhibiting spontaneous deafness and pigmentation abnormalities reminiscent of human Waardenburg Syndrome Type 2 (WS2: OMIM#193510). Through phenotypic characterization, including coat color, skin, eye morphology, and auditory brainstem response (ABR) assessments, we identified hypopigmentation and complete deafness in mutant porcupines.
