MiR-195-5p was down-regulated in NSCLC tissues. Interestingly, SCC patients showed lower miR-195-5p expression compared to patients with lung adenocarcinoma (ADC). In addition, functional assays proved that miR-195-5p overexpression inhibited the proliferation, migration, and invasion of NSCLC-derived cells by directly targeting CPNE1. Pathway analysis showed decreased expression of p-AKT, p-Erk, and Snail after transfection with miR-195-5p mimics in both lung adenocarcinoma and squamous cell lines. Conclusion Our findings suggested that miR-195-5p regulation contributed to the differential expression of CPNE1 in NSCLC subtypes. © The author(s).Objectives This study aims to evaluate influence factors for adjuvant chemotherapy regimen choice on the basis of trastuzumab in older human epidermal growth factor receptor 2 (HER2)-positive breast cancer under multi-disciplinary team (MDT) modality. Materials and Methods HER2-positive breast cancer patients aged ≥ 60 years who received breast cancer surgery between April 2013 and December 2017 in Shanghai Ruijin Hospital were retrospectively enrolled. Clinical and pathological features, MDT recommendations, administration of adjuvant treatment, cardiotoxicity, and disease outcome information were reviewed and analyzed. Results A total of 222 older HER2-positive breast cancer patients were included and recommended to receive adjuvant chemotherapy plus trastuzumab therapy. Paclitaxel plus trastuzumab (PH, 41/222, 18.5%), docetaxel plus carboplatin and trastuzumab (TCH, 62/222, 27.9%), and antharcyclines plus cyclophosphamide followed by taxanes and trastuzumab (AC-TH, 119/222, 53.6%) were the three main regimens. Patients with T1a-b (P less then 0.001), grade 1-2 (P=0.008), node-negative (P less then 0.001), stage I (P less then 0.001), low Ki-67 level (P less then 0.001) disease, with cardiovascular comorbidities (P=0.011), and aged ≥ 70 years (P less then 0.001) were more likely to be recommended to PH regimen. Among the 178 patients who finally received adjuvant chemotherapy plus one-year trastuzumab treatment, only four patients (4/117, 3.4%) were recorded to have asymptomatic LVEF declining ≥ 10% but remaining ≥ 50% within one-year trastuzumab treatment. Conclusions Clinical factors, including age, tumor size, node status, and cardiovascular comorbidity influenced the recommendation of trastuzumab with chemotherapy for older HER2-positive breast cancer patients. Low risk older HER2-positive breast cancer patients treated with PH had favorable outcome and good cardiac safety, which needed further clinical validation. © The author(s).MicroRNAs (miRNAs or miRs) is a non-coding small RNA of a type of 18~24 nucleotide-regulated gene that has been discovered in recent years. It mainly degrades the target gene mRNA or inhibits its translation process through the complete or incomplete bindings with 3'UTR of target genes, followed by the regulation of individual development, apoptosis, proliferation, differentiation and other life activities through the post-transcriptional regulation. Among many miRNAs, the microRNA family, miR-30, plays diverse roles in these key process of neoplastic transformation, metastasis, and clinical outcomes in different cancer progression. As key member of miR-30, miR-30c is regulated by oncogenic transcription factors and cancer progression related genes. Recently, numerous studies have demonstrated that the aberrant expression of miR-30c was significantly associated with the majority of human cancer progression. In this review, the diverse roles of miR-30c in different cancer progression such as the cellular and molecular mechanisms, the potential applications in clinics were summarized to speculate the benefits of miR-30c over-expression in cancer treatment and prognosis. © The author(s).Tumor associated neutrophils (TANs) play important roles in the progress of CRC. Since tumor microenvironments could influence the phenotypes of TANs, altering the tumor microenvironment to polarize the phenotype of TANs may be a new strategy for tumor treatment. This study aims to investigate the effect of anti-TGF-β on the polarization of TANs from a pro-tumor phenotype towards an anti-tumor phenotype in CRC. In this work, CRC patients had more infiltration of TANs and higher expression of TGF-β in CRC tissue when compared with the controls. In vitro, SW480 cells were co-cultured with primed neutrophils, which simulated the TANs in the tumor microenvironment, and TGF-β was blocked by anti-TGF-β (1D11) in order to polarize TANs. Anti-TGF-β treatment increased the cytotoxicity of TANs and decreased the metastatic chemoattractants secreted by TANs, and ultimately increased the apoptosis of CRC cells significantly while remarkably suppressing the migration of tumor cells. The changes of signaling pathways in the TANs and tumor cells were explored. The results showed that anti-TGF-β attenuated CRC may be partly mediated by suppression of PI3K/AKT signaling pathways in TANs and partly mediated by suppression of TGF-β/Smad signaling pathways in tumor cells. Furthermore, the tumor in the mice treated with 1D11 was obviously smaller and had reverse tumorigenesis compared with the controls, while neutrophil depletion reduced the anti-tumor effect of 1D11. Our data suggest that anti-TGF-β attenuates tumor growth via the polarization of TANs to an anti-tumor phenotype in CRC, which provides new strategies for CRC treatment. © The author(s).The long, noncoding RNA (lncRNA) PVT1, as an important epigenetic regulator, has a critical role in carcinogenesis. However, its role in pancreatic ductal adenocarcinoma (PDAC) has not been fully investigated. Here, the up-regulated expression of lncRNA PVT1 is found in our PDAC tumor samples. Knockdown of it suppressed PDCA cells growth and glycolysis. An inverse association between miR-519d-3p and PVT1 was found. RIP, RNA pulldown and luciferase assay showed that PVT1 directly targets miR-519d-3p by binding with microRNA binding site. buy JPH203 Bioinformatics analysis and study indicated that HIF-1A is a target of miR-519d-3p. Collectively, our findings suggested that PVT1 could act as an oncogenic lncRNA, and promote tumor progression by regulating HIF-1A via competing with miR-519d-3p. © The author(s).
