目的探讨深低温冻储对大鼠同种异体移植气管上皮再生的影响。方法用深低温冻储2周和6周的大鼠气管进行同种异体气管移植,以自体和异体新鲜气管作为对照,通过观察供体气管的组织学、上皮爬行和再生情况,评价深低温冻储不同时长对移植气管的存活和新生上皮再生的作用。结果深低温冻储6周后实验组的移植气管复层上皮比自体气管移植组厚度明显变薄或成单层,软骨无变性坏死,未见有单核细胞浸润,最长存活达35 d,而深低温冻储2周气管移植大鼠为10 d。结论深低温冷冻后的组织可以保持其原有的活力和组织完整性,并能消减供体气管的抗原性。冻储6周的移植气管上皮再生和受体的存活率要优于冻储2周组。

BACKGROUND Thrombocytopenia 2,an autosomal dominant inherited disease characterized by moderate thrombocytopenia,predisposition to myeloid malignancies and normal platelet size and function,can be caused by 5’-untranslated region(UTR)point mutations in ankyrin repeat domain containing 26(ANKRD26).Runt related transcription factor 1(RUNX1)and friend leukemia integration 1(FLI1)have been identified as negative regulators of ***,the positive regulators of ANKRD26 are still *** To prove the positive regulatory effect of GATA binding protein 2(GATA2)on ANKRD26 *** Human induced pluripotent stem cells derived from bone marrow(hiPSC-BM)INTRODUCTION Ankyrin repeat domain containing protein 26(ANKRD26)acts as a regulator of adipogenesis and is involved in the regulation of feeding behavior[1-3].The ANKRD26 gene is located on chromosome 10 and shares regions of homology with the primate-specific gene family *** to the Human Protein Atlas database,the ANKRD26 protein is localized to the Golgi apparatus and vesicles,and its expression can be detected in nearly all human tissues[4].Moreover,UniProt annotation revealed that ANKRD26 is localized in the centrosome and contains coiled-coil domains formed by spectrin helices and ankyrin repeats[5,6].The most common disease related to ANKRD26 is thrombocytopenia 2(THC2),which is a rare autosomal dominant inherited disease characterized by lifelong mild-to-moderate thrombocytopenia and mild bleeding[7-9].Caused by the variants in the 5’-untranslated region(UTR)of ANKRD26,THC2 is defined by a decrease in the number of platelets in circulating blood and results in increased bleeding and decreased clotting ability[8,10].Due to the point mutations that occur in the 5’-UTR of ANKRD26,its negative transcription factors(TFs),Runt related transcription factor 1(RUNX1)and friend leukemia integration 1(FLI1),lose their repression effect[11].The persistent expression of ANKRD26 increases the activi

Background The genetic diversity of yak, a key domestic animal on the Qinghai-Tibetan Plateau(QTP), is a vital resource for domestication and breeding efforts. This study presents the first yak pangenome obtained through the de novo assembly of 16 yak *** We discovered 290 Mb of nonreference sequences and 504 new genes. Our pangenome-wide presence and absence variation(PAV) analysis revealed 5,120 PAV-related genes, highlighting a wide range of variety-specific genes and genes with varying frequencies across yak populations. Principal component analysis(PCA) based on binary gene PAV data classified yaks into three new groups: wild, domestic, and Jinchuan. Moreover, we pro-posed a ‘two-haplotype genomic hybridization model' for understanding the hybridization patterns among breeds by integrating gene frequency, heterozygosity, and gene PAV data. A gene PAV-GWAS identified a novel gene(Bos-Gru3G009179) that may be associated with the multirib trait in Jinchuan yaks. Furthermore, an integrated transcrip-tome and pangenome analysis highlighted the significant differences in the expression of core genes and the muta-tional burden of differentially expressed genes between yaks from high and low altitudes. Transcriptome analysis across multiple species revealed that yaks have the most unique differentially expressed m RNAs and lnc RNAs(between high- and low-altitude regions), especially in the heart and lungs, when comparing high- and low-altitude *** The yak pangenome offers a comprehensive resource and new insights for functional genomic studies, supporting future biological research and breeding strategies.
