Premise Of The Study: To survey population variation and the adaptive evolution of Cephalotaxus fortunei (Cephalotaxaceae), an endemic and endangered conifer in China, microsatellite markers were developed and characterized for this species.
Methods And Results: Based on the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) protocol, 15 microsatellite markers were developed for C. fortunei, 13 of which were polymorphic within a sample of 75 individuals representing five natural populations. The number of alleles per locus ranged from one to seven. The expected and observed heterozygosities were 0.108-0.738 and 0.000-1.000, respectively. Ten polymorphic loci were also successfully amplified in C. oliveri.
Conclusions: These polymorphic loci provide a valuable tool for population genetic analysis of C. fortunei, which will contribute to its management and conservation.

Microsatellite stable (MSS) colorectal cancer (CRC) is a subtype of CRC that generally exhibits resistance to immunotherapy, particularly immune checkpoint inhibitors such as PD-1 blockade. This study investigates the effects and underlying mechanisms of combining PD-1 blockade with IDO1 inhibition in MSS CRC. Bioinformatics analyses of TCGA-COAD and TCGA-READ cohorts revealed significantly elevated IDO1 expression in CRC tumors, correlating with tumor mutation burden across TCGA datasets.

Background: Classical genome-wide association studies (GWAS) of Alzheimer's disease (AD), which successfully identified over 75 risk loci to date, are limited to the content of the imputation panels that typically do not cover all types of genetic variation, e.g., tandem repeats encompassing >55% of human genome.

Background: Studies of the genetics of Alzheimer's disease (AD) have largely focused on single nucleotide variants and short insertions/deletions. However, much of the disease heritability has yet to be uncovered, suggesting that other forms of genetic variation promote substantial portions of genetic risk. Uncovering the genetic basis of AD can lead to new disease biomarkers and delineate disease mechanisms.

Introduction: Malaria molecular surveillance (MMS) can provide insights into transmission dynamics, guiding national control programs. We previously designed AmpliSeq assays for MMS, which include different traits of interest (resistance markers and deletions), and SNP barcodes to provide population genetics estimates of and parasites in the Peruvian Amazon. The present study compares the genetic resolution of the barcodes in the AmpliSeq assays with widely used microsatellite (MS) panels to investigate population genetics of Amazonian malaria parasites.

Microsatellite markers are cost-effective, rapid, efficient, and show great advantages in in large-sample kinship analysis and population structure studies. However, microsatellite loci are seriously underdeveloped in non-model organisms. The plateau zokor (Eospalax baileyi) is a key species living underground in the Tibetan Plateau, the effective management of which has long been challenging.
