Background: Previously, we first identified the human tripartite motifcontaining protein 45 (TRIM45) acts as a novel transcriptional repressor in mitogenactivated protein kinase (MAPK) signaling pathway. After that, the inhibitory role of TRIM45 in the development of tumor was gradually unveiled. However, the function of TRIM45 in the tumorigenesis of lung cancer has not been characterized. Methods and Results: In this study, we found that TRIM45 was up-regulated in earlystage human non-small-cell lung cancer (NSCLC) tissues. Overexpression of TRIM45 in lung cancer cells induces G1 arrest and promotes apoptosis, which accompanied by upregulated expression of RB, p16, p53, p27Kip1, and Caspase3 and down-regulated expression of CyclinE1 and CyclinE2. Further detection of the expression of the molecules in the MAPK signaling pathway revealed that overexpression of TRIM45 in lung cancer cells promotes phosphorylated p38 (p-p38) activation and inhibits phosphorylated ERK (p-ERK) activation. In accordance with this, p-p38 is increased while p-ERK is decreased in lung cancer tissues. Conclusion: These findings indicate that TRIM45 plays an inhibitory role in the tumorigenesis of lung cancer. High-level expression of TRIM45 in lung cancer tissue may promote cell apoptosis by activating p38 signal and inhibit proliferation by down-regulating p-ERK, which provides a new clue for understanding the tumorigenesis of lung cancer.

AbstractBRAF and KRAS are two key oncogenes in the RAS/RAF/MEK/MAPK signaling pathway. Concomitant mutations in both KRAS and BRAF genes have been identified in non-small cell lung cancer (NSCLC). They lead to the proliferation, differentiation, and apoptosis of tumor cells by activating the RAS/RAF/MEK/ERK signaling pathway. To date, agents that target RAS/RAF/MEK/ERK signaling pathway have been investigated in NSCLC patients harboring BRAF mutations. BRAF and MEK inhibitors have gained approval for the treatment of patients with NSCLC. According to the reported findings, the combination of MEK inhibitors with chemotherapy, immune checkpoint inhibitors, epidermal growth factor receptor-tyrosine kinase inhibitors or BRAF inhibitors is highly significant for improving clinical efficacy and causing delay in the occurrence of drug resistance. This review summarized the existing experimental results and presented ongoing clinical studies as well. However, further researches need to be conducted to indicate how we can combine other drugs with MEK inhibitors to significantly increase therapeutic effects on patients with lung cancer.

Ivosidenib is an isocitrate dehydrogenase mutant inhibitor that the US Food and Drug Administration recently approved for the treatment of leukemia. Studies suggested that ivosidenib may inhibit the progression of non-small cell lung cancer (NSCLC). In the present study, we explored RNAs and their potential regulatory mechanisms by which ivosidenib treats NSCLC cells. We used MTT assays, Transwell assays, and flow cytometry to measure the anti-tumor effects of ivosidenib in NSCLC cells. We performed whole transcriptome sequencing to determine differentially expressed mRNAs (DE-mRNAs) and non-coding RNAs (ncRNA). We used GO and KEGG pathway enrichment analyses to identify the functions and potential mechanisms. According to miRNA target interactions, we constructed a competing endogenous network. Ivosidenib inhibited the proliferation, invasion, and migration of NSCLC cells and inhibited tumor growth in vivo. We identified 212 DE-mRNAs, four DE-miRNAs, and 206 DE-lncRNAs in ivosidenib-treated NSCLC cells compared to untreated NSCLC cells. DE-mRNAs were significantly enriched in the cancer-associated pathways, including the TGF-β signaling pathway, the PI3K-Akt signaling pathway, the Jak-STAT signaling pathway, the MAPK signaling pathway, the Rap1 signaling pathway, and cell adhesion molecules. Based on the competing endogenous RNA hypothesis, we constructed lncRNA-miRNA-mRNA networks to elucidate the regulatory relationships between mRNA and ncRNA. We found that qRT-PCR results showed corresponding expression trends of differential genes with sequencing data. Our results provide insights into the molecular basis of ivosidenib suppression of NSCLC.
