生物谷BIOON/ --近日,国际学术期刊cell death &differentiation 在线发表了美国科学家的一项最新研究进展,他们发现单磷酸鸟苷酸合成酶(GMPS)在恶性黑色素瘤的侵袭转移过程中具有重要作用,同时他们还找到一种GMPS抑制因子可能对于恶性黑色素瘤细胞侵袭和成瘤能力具有重要抑制作用。
 
恶性黑色素瘤是由皮肤和其他器官黑素细胞产生的肿瘤,是人类肿瘤中转移能力最强的肿瘤之一。许多研究表明获得侵袭能力是黑色素瘤转移的先决条件,所以了解黑色素瘤侵袭发生的分子机制对于设计黑色素瘤治疗干预药物具有非常重要的意义。
 
在该项研究中,研究人员发现鸟苷酸从头合成途径的关键酶--单磷酸鸟苷酸合成酶(GMPS)对于来源于人类转移性黑色素瘤的BRAFv600e或NRASq61r突变细胞的侵袭和成瘤能力具有非常重要的作用。并且相比于良性黑色素瘤,GMPS的表达水平在人类转移性黑色素中显著增加,这表明GMPS可能是抗黑色素瘤治疗方法的潜在靶向目标。狭霉素A是由Streptomyces hygroscopius产生的一种核苷类似物能够抑制GMPS活性,在这项研究中,研究人员首次发现狭霉素A能够有效抑制黑色素瘤细胞的侵袭和成瘤能力。
 
这项研究表明GMPS是增强黑色素瘤细胞侵袭的重要驱动因子,同时还证明狭霉素a可能通过GMPS抑制黑色素瘤细胞侵袭和成瘤,但需要进一步研究验证这一发现。
