TRIM67 Knockout HEK293T RIPA Lysate(TRIM67基因敲除HEK293T细胞RIPA裂解液)是通过同时表达Cas9、目的基因sgRNA和puromycin抗性基因并实现了目的基因CRISPR敲除的多克隆HEK293T细胞的RIPA裂解液。该细胞中目的基因的敲除已经通过T7EI法的验证。本产品可用于该目的基因敲除后其信号通路相关蛋白的研究，也可以用于该基因相应抗体的验证。
本RIPA裂解液源于可同时表达Cas9、目的基因sgRNA和puromycin抗性基因的慢病毒感染HEK293T细胞并经过puromycin筛选后获得的多克隆细胞。制备该细胞的相应慢病毒的基因序列的关键图谱信息请参考图1。

由于本细胞是通过CRISPR/Cas9技术获得的多克隆细胞，基于CRISPR/Cas9技术的特点，理论上平均有2/3的细胞发生移码突变而导致了目的基因的敲除，平均有1/3的细胞并未发生移码突变。很多情况下有约2/3的细胞发生目的基因的敲除，已经足以进行很多的目的基因的生物学功能的研究了。如果希望获得100%基因敲除的细胞，可以自行使用本产品筛选单克隆细胞，或者委托碧云天进行单克隆细胞株的筛选服务。
本RIPA裂解液用于实验时，建议同时选购无任何靶向的对照细胞RIPA裂解液Control Knockout HEK293T RIPA Lysate (L00025)或靶向GFP的对照RIPA裂解液GFP Knockout HEK293T RIPA Lysate (L00027)。

| Gene Summary | Tripartite motif (TRIM) proteins have been increasingly appreciated as important antiviral factors that suppress the replication of a wide range of RNA and DNA viruses. TRIM proteins inhibit viral replication by either directly targeting viral components or modulating innate immune responses that result in antiviral gene expression. For example, TRIM19 (also known as promyelocytic leukemia protein (PML)) restricts multiple RNA viruses and DNA viruses, including herpesviruses, by organizing PML nuclear bodies. Several TRIM proteins that suppress KSHV reactivation. TRIM67, was commonly silenced in colorectal cancer and its downregulation was associated with poor survival. Trim67 knockout in ApcMin/+ mice increased the incidence, multiplicity, and burden of colorectal tumors. Similarly, colon-specific knockout of Trim67 significantly accelerated azoxymethane-induced colorectal cancer in mice. RNA sequencing revealed that the antitumor effect of TRIM67 was mediated by activation of the p53 signaling pathway. TRIM67 interacted directly with the C-terminus of p53, inhibiting p53 degradation by its ubiquitin ligase MDM2. TRIM67 was also a transcriptional target of p53; upon cellular stress, p53 bound to the TRIM67 promoter and induced significant upregulation of TRIM67, thereby forming a TRIM67/p53 self-amplifying loop that boosts p53-induced cell growth inhibition and apoptosis. Consequently, loss of this p53-positive regulatory program profoundly compromised p53-mediated responses to chemotherapy-induced DNA damage. Dampened p53 response was also observed in tumors of Trim67 knockout mice and Trim67 knockout embryonic fibroblasts. TRIM67 reactivation restored p53 activation and sensitized colorectal cancer cells to chemotherapy in vitro and in vivo. TRIM67 thus functions as a pivotal tumor suppressor in colorectal cancer and is a potential target for improving chemotherapy responsiveness. |
