Platinum-based chemotherapy remains the best strategy for most patients. New targeted drugs, including mAbs and small molecules, are currently under clinical investigation for treating NSCLC patients. Areas covered: The authors of this article focus on farletuzumab , a mAb targeting folate receptor, which has been studied in ovarian cancer and various other malignancies. In this review, the authors review its potential as therapy for NSCLC, because of the biological rationale provided by the expression of folate receptor α in most of lung adenocarcinoma. The authors provide details of farletuzumab's mechanism of action and discuss the results from completed Phase I and Phase II clinical trials. They also highlight ongoing trials. Expert opinion: There are an increasing number of treatment options for NSCLC and it is hoped that farletuzumab could be added to them. That being said, further evidence for its use with NSCLC patients is still needed. It could have a synergic effect with pemetrexed, because these two drugs have a similar target, namely the folate pathway. This combined action could provide an improved efficacy, although there are some concerns about increased toxicity. However, the authors do note that the combination of farletuzumab with other cytotoxic drugs has not been shown to increase toxicity alone.

We investigate on the molecular mechanism by which miR-182 could regulate thrombospondin-1 (TSP-1) expression, a protein downregulated in CRC and inversely correlated with tumor vascularity and metastasis. Background: MicroRNAs are small non-coding RNAs that regulate the expression of different genes, involved in cancer progression, angiogenesis and metastasis. miR-182, over-expressed in colorectal cancer (CRC), has like predictive target thrombospondin-1 (TSP-1), a protein inversely correlated with tumor vascularity and metastasis that results downregulated in different types of cancer including CRC. Results: We found that TSP-1 increased after transfection with anti-miR-182 and we showed that miR-182 targets TSP-1 3¢UTR-mRNA in both cells. Moreover, we observed that anti-miR-182 did not induce significant variation of Egr-1 expression, but affected the nuclear translocation and its binding on tsp-1 promoter in HCT-116. Equally, Sp-1 was slightly increased as total protein, rather we found a nuclear accumulation and its loading on the TSP-1 promoter in HT-29 transfected with anti-miR-182. Conclusion: Our data suggest that miR-182 targets the anti-angiogenic factor TSP-1 and that anti-miR-182 determines an upregulation of TSP-1 expression in colon cancer cells. Moreover, anti-miR-182 exerts a transcriptional regulatory mechanism of tsp-1 modulating Egr-1 and Sp-1 function. Anti-miR-182 could be used to restore TSP-1 expression in order to contrast angiogenic and invasive events in CRC.
