Although the tumor suppressor P53 is known to regulate a broad network of signaling pathways,it is still unclear how certain drugs influence these P53 signaling networks.Here,we used a comprehensive single-cell multiomics view of the effects of ginsenosides on cancer cells.Transcriptome and proteome profiling revealed that the antitumor activity of ginsenosides is closely associated with P53 protein.A miRNA-proteome interaction network revealed that P53 controlled the transcription of at least 38 proteins,and proteome-metabolome profiling analysis revealed that P53 regulated proteins involved in nucleotide metabolism,amino acid metabolism and “Warburg effect”.The results of integrative multiomics analysis revealed P53 protein as a potential key target that influences the anti-tumor activity of ginsenosides.Furthermore,by applying affinity mass spectrometry (MS) screening and surface plasmon resonance fragment library screening,we confirmed that 20(S)-protopanaxatriol directly targeted adjacent regions of the P53 DNA-binding pocket and promoted the stability of P53-DNA interactions,which further induced a series of omics changes.

生态型核雄性不育材料的发现是实现玉米“两系”法制种的一个重要途径,为避免玉米小斑病生理小种对特定细胞质的专化侵染,探索新的不育化制种技术对玉米种子生产具有重要意义。本研究以新发现的生态型核雄性不育材料春杂为研究对象,利用分期播种和田间叶龄调查的方法,对春杂的育性转换机制进行了研究;利用镜检的方法,对春杂不同时期的花粉育性进行研究;在春杂的不育阶段内,对春杂×87-1的亲本、F_1和F_2、BC_1
在大豆理想株型构建中,株高与叶柄长度是两个非常重要的株型性状,均对大豆产量影响显著。研究证实株高与结荚数呈现正相关性且适度矮化可以提高抗倒伏能力,叶柄长度决定了大豆整株的叶层结构并影响植株的光合作用面积,研究发现拥有较短叶柄的大豆品种可以在高密度种植下而不影响光合作用。本文利用60CO-γ射线诱变“菏豆12”产生的一个矮化短柄突变体baf6比较研究了与菏豆12的百粒重,株高,底荚高度等常见农艺性状
