Camels have evolved various resistance characteristics adaptive to their desert habitats. In the present study, we used high-throughput sequencing to investigate stress-induced alternative splicing events as well as different genes involved in resistance to water deprivation and salt absorption in the ileum and liver in . Through association analyses of mRNA, miRNA and lncRNA, we sought to explicate how camels respond to high salt and water scarcity conditions. There were two modes by which genes driven by alternative splicing were enriched to molecular functions, invoking of which was potentially fixed by organ and stress types. With qRT-PCR detection, the differentially expressed , , , , , , , and were screened as functionally important genes, along with miR-29b, miR-484, miR-362-5p, miR-96, miR-195, miR-128 and miR-148a. These genes contributed to cellular stress resistance, for instance by reducing water loss, inhibiting excessive import of sodium, improving protective barriers and sodium ion homeostasis, and maintaining uridine content. The underlying competing endogenous RNAs referred to LNC001664, let-7e and mRNA in ileum, and LNC001438, LNC003417, LNC001770, miR-199c and mRNA in liver. Besides competent interpretation to resistance, there may be inspirations for curing human diseases triggered by high-salt intake.
骆驼已经进化出了各种适应其沙漠栖息地的抗性特征。在本研究中,我们使用高通量测序来研究应激诱导的可变剪接事件,以及参与回肠和肝脏中抗缺水和盐吸收的不同基因。通过对mRNA、miRNA和lncRNA的关联分析,我们试图阐明骆驼如何应对高盐和缺水条件。可变剪接驱动的基因通过两种模式富集到分子功能,其调用可能由器官和应激类型决定。通过qRT-PCR检测,筛选出差异表达的[具体基因未给出]以及miR-29b、miR-484、miR-362-5p、miR-96、miR-195、miR-128和miR-148a作为功能重要基因。这些基因有助于细胞抗应激,例如通过减少水分流失、抑制钠的过度摄入、改善保护屏障和钠离子稳态以及维持尿苷含量。潜在的竞争性内源RNA在回肠中是LNC001664、let-7e和[具体基因未给出]mRNA,在肝脏中是LNC001438、LNC003417、LNC001770、miR-199c和[具体基因未给出]mRNA。除了对抗性的合理解释外,对于治疗由高盐摄入引发的人类疾病可能也有启示。
