01). In addition, the levels of phosphorylation induced by exogenous AREG were also inhibited by dimeric-EGCG (P less then 0.01); however, no significant effects of dimeric-EGCG were observed on epidermal growth factor or transforming growth factor-alpha signaling. Surface plasmon resonance analysis demonstrated that 10 μM dimeric-EGCG bound directly to the extracellular domain of EGFR, competitively inhibiting the binding of AREG to EGFR. These results suggest a novel mechanism underlying the inhibitory effect of dimeric-EGCG on MDA-MB-231 cells, with potential application in the development of drugs for the treatment of TNBC.The resistance of chronic myeloid leukaemia (CML) to tyrosine kinase inhibitors (TKIs) remains a significant clinical problem. Targeting alternative pathways, such as protein prenylation, is known to be effective in overcoming resistance. Simvastatin inhibits 3-hydroxy-3-methylglutaryl-CoA reductase (a key enzyme in isoprenoid-regulation), thereby inhibiting prenylation. We demonstrate that simvastatin alone effectively inhibits proliferation in a panel of TKI-resistant CML cell lines, regardless of mechanism of resistance. We further show that the combination of nilotinib and simvastatin synergistically kills CML cells via an increase in apoptosis and decrease in prosurvival proteins and cellular proliferation. Mechanistically, simvastatin inhibits protein prenylation as shown by increased levels of unprenylated Ras and rescue experiments with mevalonate resulted in abrogation of synergism. The combination also leads to an increase in the intracellular uptake and retention of radio-labelled nilotinib, which further enhances the inhibition of Bcr-Abl kinase activity. In primary CML samples, this combination inhibits clonogenicity in both imatinib-naive and resistant cells. Such combinatorial effects provide the basis for utilising these Food and Drug Administration-approved drugs as a potential clinical approach in overcoming resistance and improving CML treatment.Lung cancer is the most frequent cause of cancer-related death worldwide and is usually diagnosed in advanced stages. Among those, approximately 7.4% of non-small cell lung cancer (NSCLC) patients will have brain metastasis (BM) at presentation, and 25-30% will develop BM during the course of their disease. To date, patients with BMs are increasingly considered for combined treatment using systemic immune checkpoint inhibition (ICI) and cranial radiation therapy (RT); yet, there is limited data regarding the safety of this approach. Here, we report two cases of NSCLC patients treated with two different types of cranial RT and ICIs.Chronic myeloid leukemia (CML) is a type of myeloproliferative neoplasm. Aberrant expression of long noncoding RNA highly upregulated in liver cancer (HULC) has been implicated in tumor progression, including CML. This study aimed to investigate the role of HULC in CML. The levels of HULC, miR-150-5p and myeloid cell leukemia 1 (MCL1) were examined by quantitative real-time PCR or western blot assay. Cell counting kit-8 assay was used to detect cell viability and half inhibition concentration. Cell apoptosis was monitored by flow cytometry and western blot. The interaction among HULC, miR-150-5p and MCL1 was validated by dual-luciferase reporter assay. The expression of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT) and phosphorylation-AKT was evaluated using western blot assay. HULC and MCL1 were upregulated, whereas miR-150-5p was downregulated in bone marrow mononuclear cells of CML patients and CML cells. HULC overexpression increased imatinib resistance in K562 cells, and HULC depletion enhanced imatinib sensitivity in imatinib-resistant cells (K562-R). Mechanically, HULC was a sponge of miR-150-5p. HULC contributed to imatinib resistance through regulation of miR-150-5p. MCL1 bound to miR-150-5p and reversed the effect of HULC on imatinib resistance. HULC regulated the PI3K/AKT pathway via the miR-150-5p/MCL1 axis. These findings indicated that HULC enhanced imatinib resistance in CML by modulating the miR-150-5p/MCL1 axis, providing a promising biomarker for CML.Lung cancer is one of the most important and lethal cancers in the world. Human epidermal growth factor 2 (HER2) is a member of the erbB receptor tyrosine kinase family. The incidence of HER2 kinase domain mutations in adenocarcinoma of lung ranges from 1% to 3%. HER2 V659D mutation is located in the trans-membrane domain (TMD) with only a few cases reported before, and importantly, there were no more standard and effective ways for this kind of diseases until now. Afatinib irreversibly blocks all kinase-competent HER family members. Apatinib is one of the small-molecule oral anti-angiogenesis-targeted agents developed firstly in China, and it's a highly selective inhibition of the activity of VEGFR-2. This report presents an advanced lung adenocarcinoma patient with HER2 V659D mutation who was treated with combination of Afatinib and Apatinib. He achieved good efficacy and tolerable adverse reactions.Colorectal cancer is a common cancer worldwide. Several risk factors have been described, such as age, lifestyle and family history. Inflammatory bowel diseases (IBD) are a well-recognized risk factor for the development of colorectal cancer. However, the onset of an IBD de novo in the context of the treatment of a colorectal neoplasia has not been reported before, except in the context of the treatment with immunocheckpoint inhibitors. Fifty-nine-years old man diagnosed with a metastatic colorectal cancer who received conventional treatment with chemotherapy and an antiangiogenic inhibitor. The patient had a complete response with the therapy after few cycles. Nevertheless, during the treatment, the patient presented with rectal bleeding, and was diagnosed with ulcerative colitis. Although the treatment was discontinued, tumoral complete remission is maintained. The relevance of this case lies in the concurrence of the onset of an autoimmune disease and a complete response of the malignancy. The concurrence of these events has been described previously only with immunotherapy. There are not cases reported involving chemotherapy and antiangiogenic drugs. selleck chemicals Other causes of colitis were ruled out due to the unusual presentation of the case.
