|title=Contribution of senescence in human endometrial stromal cells during proliferative phase to embryo receptivity†.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/32285109
|abstract=Successful assisted reproductive technology pregnancy depends on the viability of embryos and endometrial receptivity. However, the literature has neglected effects of the endometrial environment during the proliferative phase on implantation success or failure. Human endometrial stromal cells (hESCs) were isolated from endometrial tissues sampled at oocyte retrieval during the proliferative phase from women undergoing infertility treatment. Primary hESC cultures were used to investigate the relationship between stemness and senescence induction in this population and embryo receptivity. Patients were classified as receptive or non-receptive based on their pregnancy diagnosis after embryo transfer. Biomarkers of cellular senescence and somatic stem cells were compared between each sample. hESCs from non-receptive patients exhibited significantly higher (P < 0.01) proportions of senescent cells, mRNA expressions of [[[[CDKN2A]]]] and [[CDKN1A]] transcripts (P < 0.01), and expressions of genes encoding the senescence-associated secretory phenotype (P < 0.05). hESCs from receptive patients had significantly higher (P < 0.01) mRNA expressions of [[ABCG2]] and [[ALDH1A1]] transcripts. Our findings suggest that stemness is inversely associated with senescence induction in hESCs and, by extension, that implantation failure in infertility treatment may be attributable to a combination of senescence promotion and disruption of this maintenance function in this population during the proliferative phase of the menstrual cycle. This is a promising step towards potentially improving the embryo receptivity of endometrium. The specific mechanism by which implantation failure is prefigured by a loss of stemness among endometrial stem cells, and cellular senescence induction among hESCs, should be elucidated in detail in the future.

|title=[[ABCG2]] rs2231142 variant in hyperuricemia is modified by [[SLC2A9]] and [[SLC22A12]] polymorphisms and cardiovascular risk factors in an elderly community-dwelling population.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/32183743
|abstract=The [[ABCG2]] rs2231142 single nucleotide polymorphism (SNP) is one of the most significant genetic variants associated with hyperuricemia (HUA) in Asian populations. However, the risk of [[ABCG2]] rs2231142 variants for HUA could interact with other important HUA risk variants and cardiovascular factors. This study investigated the effects of the combined association among [[ABCG2]] rs2231142 and multiple HUA genetic variants or cardiovascular risk factors on HUA risk and serum uric acid (sUA) levels in an elderly Chinese population. A total of 1206 participants over 65 years old were enrolled in this study. Physical and laboratory examinations were performed for all participants. The [[ABCG2]] rs2231142, [[SLC2A9]] rs3733591, and [[SLC22A12]] rs893006 SNPs were assayed using a standardized protocol. Logistic regression analysis and liner regression were adjusted respectively to account for the association between [[ABCG2]] rs2231142 and other genetic variants, as well as between cardiovascular risk factors and HUA risk and sUA levels. The prevalence of HUA was 14.71% in the elderly community-dwelling population. The [[ABCG2]] rs2231142 risk T allele was associated with HUA risk (odds ratio (OR) = 1.63, 95% confidence interval (CI): 1.27-2.11; p = 1.65 × 10 ) and with increased sUA levels (Beta = 0.16, p = 6.75 × 10 ) in the whole study population. Linear regression analysis showed that the mean sUA level increased linearly with the number of risk alleles of the three candidate genetic variants (Beta = 0.18, p = 1.94 × 10 ) The joint effect of the [[ABCG2]] rs2231142 T allele and cardiovascular risk factors (obesity, hypertension and dyslipidemia) was also associated with increased HUA risk and sUA levels. Each copy of the risk T allele was significantly associated with enhanced HUA risk in patients with hypertriglyceridemia (OR = 2.52, 95% CI: 1.33-4.60; p = 0.003) compared to controls. Our findings reinforce the importance of the [[ABCG2]] rs2231143 variant as a crucial genetic locus for HUA in Chinese populations and demonstrated the combined effects of multiple genetic risk variants and cardiovascular risk exposures on HUA risk and increased sUA level.

|title=Morphological and immunohistochemical characteristics of the equine corneal epithelium.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/30767359
|abstract=The morphology of the corneal epithelium in two age groups of horses is described. Distribution patterns of proliferation-, differentiation-, stem cell-associated markers and cell junction proteins were assessed. Corneal samples from 12 horses (six foals and six adult horses) were analyzed after H
