MYC is an oncogenic transcription factor with a novel role in enhancing global transcription when overexpressed. However, how MYC promotes global transcription remains controversial. Here, we used a series of MYC mutants to dissect the molecular basis for MYC-driven global transcription. We found that MYC mutants deficient in DNA binding or known transcriptional activation activities can still promote global transcription and enhance serine 2 phosphorylation(Ser2P) of the RNA polymerase(Pol) II Cterminal domain(CTD), a hallmark of active elongating RNA Pol II. Two distinct regions within MYC can promote global transcription and Ser2P of Pol II CTD. The ability of various MYC mutants to promote global transcription and Ser2P correlates with their ability to suppress CDK9 SUMOylation and enhance positive transcription elongation factor b(P-TEFb) complex formation. We showed that MYC suppresses CDK9 SUMOylation by inhibiting the interaction between CDK9 and SUMO enzymes including UBC9 and PIAS1. Furthermore, MYC's activity in enhancing global transcription positively contributes to its activity in promoting cell proliferation and transformation. Together, our study demonstrates that MYC promotes global transcription, at least in part, by promoting the formation of the active P-TEFb complex via a sequence-specific DNA-binding activity-independent manner.

失效的“压舱石”:经济安全化的现实转向

经济安全化是国家通过安全叙述将非安全的经济议题转化为安全议题的过程。在国家认为经济合作的收益将损害其在权力竞争中的整体所得时,或者在国家间政治外交关系遇到巨大震荡或冲击时,国家安全逻辑会超越经济逻辑而生效。此时,安全与经济问题在刻意煽动下交织碰撞,国家间密切的经贸关系不仅难以成为管控两国矛盾与分歧的“压舱石”,反而会被国家视作现存的“安全威胁”,成为某些国家中断或破坏双边政治经济联系的借口与手段。国家间存在的经济相互依赖关系也会随之成为安全化操纵国维护与拓展权力、进行地缘政治竞争和打击、操纵他国的战略性工具。因此,文章以存在紧密经济相互依赖的中美与俄欧关系为案例,在比较中美、俄欧之间不同经济安全化动因的基础上,分析经济安全化转向背后的选择逻辑,为中国更好地应对经济安全化挑战、更有针对性地发挥“经济压舱石”作用提供一定思考。

AIM To explore the correlation of metabolomics profiles ofgastric cancer(GC) with its chromosomal instability(CIN) *** Nineteen GC patients were classified as CIN and nonCIN type by The Cancer Genome Atlas Research Group system, based on 409 oncogenes and tumor suppressor genes sequenced. The aqueous metabolites of the GC tumor and its surrounding adjacent healthy tissues were identified through liquid chromatographymass spectrometry. Groups were compared by defining variable importance in projection score of > 1.2, a fold change value or its reciprocal of > 1.2, and a P value of < 0.05 as a significant *** In total,twelve men and seven women were enrolled, with a median age of 66 years(range, 47-87 years). The numbers of gene alterations in the CIN GC group were significantly higher than those in the non-CIN GC(32-218 vs 2-17; P < 0.0005). Compared with the adjacent healthy tissues, GC tumors demonstrated significantly higher aspartic acid, citicoline, glutamic acid, oxidized glutathione, succinyladenosine, and uridine diphosphate-Nacetylglucosamine levels, but significantly lower butyrylcarnitine, glutathione hydroxyhexanoycarnitine, inosinic acid, isovalerylcarnitine, and threonine levels(all P < 0.05). CIN tumors contained significantly higher phosphocholine and uridine 5'-monophosphate levels but significantly lower beta-citryl-L-glutamic acid levels than did non-CIN tumors(all P < 0.05). CIN GC tumors demonstrated additional altered pathways involving alanine, aspartate, and glutamate metabolism, glyoxylate and dicarboxylate metabolism, histidine metabolism, and phenylalanine, tyrosine, and tryptophan *** Metabolomic profiles of GC tumors and the adjacent healthy tissue are distinct, and the CIN status is associated with downstream metabolic alterations in GC.
