表型提示
MGI:88373Homozygotes for targeted null mutations exhibit high neonatal hypoglycemia and mortality, reduced epididymal fat pad weight, susceptibility to Listeria monocytogenes, female sterility, impaired mammary development, and resistance to skin carcinogenesis.
C/EBPβ(CCAAT/增强子结合蛋白β)是一种在多种细胞类型中表达的转录因子,属于C/EBP家族。它在细胞的分化、增殖、凋亡以及炎症反应等过程中发挥着重要的作用。C/EBPβ通过与DNA上的特定序列结合,激活或抑制下游基因的表达,从而调节细胞的生理功能和病理过程。

C/EBPβ在多种疾病的发生和发展中发挥着重要作用。例如,在结直肠癌中,慢性应激引起的肾上腺素通过β2-肾上腺素受体促进C/EBPβ的表达,进而激活TRIM2/P53信号通路,导致上皮-间质转化和肿瘤干细胞形成,从而促进结直肠癌的发展[1]。此外,C/EBPβ的抑制与卵母细胞质量的下降有关,而褪黑激素可以通过增强C/EBPβ的表达来改善由邻苯二甲酸二(2-乙基己基)酯引起的卵巢损伤[2]。

在胶质母细胞瘤中,C/EBPβ阳性的肿瘤细胞亚群能够特异性地驱动M2型肿瘤相关巨噬细胞的形成,进而促进肿瘤的生长和恶化[3]。在骨肉瘤中,C/EBPβ通过调节下游基因CLEC5A的表达,抑制骨肉瘤细胞的增殖[4]。在神经炎症中,泛素连接酶COP1通过降解C/EBPβ,抑制神经炎症的发生[5]。在早衰症中,C/EBPβ通过激活炎症基因的表达,促进早衰症细胞的衰老[6]。在抑郁症中,circDYM可以通过与C/EBPβ结合,抑制C/EBPβ的核转位,进而抑制ZC3H4的表达,从而抑制小胶质细胞的凋亡[7]。在结直肠癌中,C/EBPβ通过增强STAT3信号通路,促进SERPINA1的表达,进而促进结直肠癌的进展[8]。在IDH1野生型胶质瘤中,C/EBPβ通过上调P4HA2的表达,促进胶质瘤的恶性生物学行为[9]。在结直肠癌中,伊曲康唑通过抑制C/EBPβ介导的糖酵解,抑制肿瘤的生长[10]。

综上所述,C/EBPβ在多种疾病的发生和发展中发挥着重要作用。它通过调节下游基因的表达,影响细胞的生理功能和病理过程。C/EBPβ的研究有助于深入理解疾病的发病机制,为疾病的治疗和预防提供新的思路和策略。
