| 1 | From tuberculosis bedside to bench:UBE2B splicing as a potential biomarker and its regulatory mechanism显示文摘Alternative splicing(AS)is an important approach for pathogens and hosts to remodel transcriptome.However,tuberculosis(TB)-related AS has not been sufficiently explored.Here we presented the first landscape of TB-related AS by long-read sequencing,and screened four AS events(S100A8-intron1-retention intron,RPS20-exon1-alternaitve promoter,KIF13B-exon4-skipping exon(SE)and UBE2B-exon7-SE)as potential biomarkers in an in-house cohort-1.The validations in an in-house cohort-2(2274 samples)and public datasets(1557 samples)indicated that the latter three AS events are potential promising biomarkers for TB diagnosis,but not for TB progression and prognosis.The excellent performance of classifiers further underscored the diagnostic value of these three biomarkers.Subgroup analyses indicated that UBE2B-exon7-SE splicing was not affected by confounding factors and thus had relatively stable performance.The splicing of UBE2B-exon7-SE can be changed by heat-killed mycobacterium tuberculosis through inhibiting SRSF1 expression.After heat-killed mycobacterium tuberculosis stimulation,231 ubiquitination proteins in macrophages were differentially expressed,and most of them are apoptosis-related proteins.Taken together,we depicted a global TB-associated splicing profile,developed TB-related AS biomarkers,demonstrated an optimal application scope of target biomarkers and preliminarily elucidated mycobacterium tuberculosis-host interaction from the perspective of splicing,offering a novel insight into the pathophysiology of TB. | Mengyuan Lyu Jian Zhou Yanbing Zhou Weelic Chong Wei Xu Hongli Lai Lu Niu Yang Hai Xiaojun Yao Sheng Gong Qinglan Wang Yi Chen Yili Wang Liyu Chen Zengwanggema Jiongjiong Zeng Chengdi Wang Binwu Ying | 2023 | Signal Transduction and Targeted Therapy2023，8，3： | 0 |
