miR-593-5p inhibit cell proliferation by targeting PLK1 in non small cell lung cancer cells

In this study, we investigate, in vitro, whether miRNA-593-5p inhibits NSCLC cell proliferation. To clarify its specific mechanism of inhibition, we used bioinformatics to predict its target genes and identified PLK1. Luciferase reporter assay confirmed the binding of miR-593-5p to the PLK1 3’-UTR in a sequence-specific manner in NSCLC cells. Additionally, we also found through Western blot and quantitative RT-PCR that miR-593-5p down-regulates the expression of PLK1 protein. Finally, PLK1 overexpression was shown to disinhibit NSCLC cell proliferation. Taken together, this evidence suggests that miR-593-5p inhibits NSCLC cell proliferation by inhibiting PLK1 expression.

Immune checkpoint inhibitor (ICI) has been proven to be a major breakthrough in patients with advanced non-small cell lung cancer. Up to now, neoadjuvant therapy using ICI are rare. However, in the context of cancer immunotherapy, neoadjuvant treatment may offer an extra advantage. In this review, we will disscuss the existing preclinical data and emerging clinical findings in the neoadjuvant setting and its potential mechanism of action. We will also highlight the potential damage and the questions that are required to be answered.

Conclusion Anlotinib effectively controlled the growth of NSCLC and improved TAO related symptoms. Anlotinib maybe normalize disordered growth of blood vessels through the VEGF signaling pathway, rather than simply inhibiting angiogenesis.

This study is registered with ClinicalTrials.gov (NCT02108964); enrolment to phase 1 is complete and the study is ongoing.FindingsBy Aug 31, 2017, 180 patients (116 [64%] women; median age 60 years (52–69); 116 [64%] with ECOG performance status 1) received nazartinib across seven dose levels: 75 mg (n=17), 100 mg (n=38), 150 mg (n=73), 200 mg (n=8), 225 mg (n=28), 300 mg (n=5), and 350 mg (n=11). Seven dose-limiting toxicities were observed in six (3%) patients who received 150 mg, 225 mg, or 350 mg nazartinib once daily. Although the maximum tolerated dose was not met, the recommended phase 2 dose was declared as 1...

. Howells Curcumin has been investigated extensively for cancer prevention, but it has been proposed that long-term treatments may promote clonal evolution and gain of cellular resistance, potentially rendering cancer cells less sensitive to future therapeutic interventions. Here, we used long-term, low-dose treatments to determine the potential for adverse effects in non-small cell lung cancer (NSCLC) cells. IC50s for curcumin, cisplatin, and pemetrexed in A549, PC9, and PC9ER NSCLC cells were evaluated using growth curves. IC50s were subsequently re-assessed following long-term, low-dose curcumin treatment and a thre...
