HOXB 9是一种含有同源异型盒结构域的转录因子,在胚胎发育和癌症进展中起重要作用。然而,HOXB 9的精确翻译后修饰(PTM)和相应的作用尚不清楚。在这里,我们报告,乙酰转移酶p300/CBP相关因子(PCAF)的相互作用和乙酰化HOXB 9在体内和体外。相反,HOXB 9的乙酰化可以被脱乙酰酶SIRT 1逆转。此外,我们发现HOXB 9在赖氨酸27(AcK 27)处被乙酰化。在功能上,与野生型HOXB 9相比,AcK 27-HOXB 9降低了其促进小鼠肺癌细胞迁移和肿瘤生长的能力。AcK 27-HOXB 9通过直接占据JMJD 6基因的启动子来抑制其靶基因Jumonji domain-containing protein 6(JMJD 6)的转录。对于临床相关性,在K27处升高的HOXB 9乙酰化预测肺腺癌患者的预后更好。总之,我们通过证明HOXB 9可以被乙酰化并且AcK 27-HOXB 9抵消野生型HOXB 9在调节肺腺癌进展中的作用来鉴定HOXB 9的第一个PTM。
HOXB9 is a homeobox domain-containing transcription factor, playing an important role in embryonic development and cancer progression. However, the precise post-translational modifications (PTMs) of HOXB9 and the corresponding roles are unclear. Here, we report that acetyltransferase p300/CBP-associated factor (PCAF) interacts with and acetylates HOXB9 both in vivo and in vitro. Conversely, the acetylation of HOXB9 can be reversed by deacetylase SIRT1. Furthermore, we found that HOXB9 is acetylated at lysine 27 (AcK27). Functionally, in contrast to the wild type HOXB9, AcK27-HOXB9 decreased its capacity in promoting lung cancer cell migration and tumor growth in mice. Mechanistically, AcK27-HOXB9 suppresses the transcription of its target gene Jumonji domain-containing protein 6 (JMJD6) by direct occupying the promoter of JMJD6 gene. For clinical relevance, elevated HOXB9 acetylation at K27 predicts a better prognosis in lung adenocarcinoma patients. Taken together, we identified the first PTM of HOXB9 by demonstrating that HOXB9 can be acetylated and AcK27-HOXB9 counteracts the role of the wild-type HOXB9 in regulating lung adenocarcinoma progression.
