In addition, mice xenograft models were constructed to test the effect of circ_0058124 on TC tumor growth in vivo. Results Circ_0058124 was highly expressed in TC and is a stable cyclic transcript, mainly located in the cytoplasm. Circ_0058124 knockdown suppressed proliferation, migration, invasion and metabolic abilities in TC cells. MiR-940 could be absorbed by circ_0058124, and the inhibition effect of its overexpression on TC progression could be reversed by overexpressed-circ_0058124. MAPK1 was a target of miR-940, and the suppression effect of its silencing on TC progression could be inverted by miR-940 inhibitor. Besides, MAPK1 expression was regulated by circ_0058124 and miR-940. Interference of circ_0058124 also reduced TC tumor growth in vivo. Conclusion Circ_0058124 might play a carcinogenic role in TC progression by regulating the miR-940/MAPK1 axis, which might provide a new idea for the treatment of TC. © 2020 Sun et al.Purpose Anlotinib, a newly developed oral small-molecule receptor tyrosine kinase inhibitor (TKI), has been shown to have encouraging activity against sarcoma. The purpose of this study was to retrospectively evaluate the safety and clinical efficacy of chemotherapy combined with anlotinib plus anlotinib maintenance in advanced/metastatic soft tissue sarcoma (STS) patients in a real-world setting in China. Patients and Methods We retrospectively collected the medical data of thirty-two patients with advanced/metastatic STS who received chemotherapy combined with anlotinib plus anlotinib maintenance therapy. The objective response rate (ORR) and disease control rate (DCR) were calculated according to the RECIST 1.1 criteria. The progression-free rates (PFRs) at three and six months, the progression-free survival (PFS) time, and adverse events were recorded. Results On the basis of investigator assessments, two patients (6%) achieved CR (complete response) and nine patients (28%) achieved PR (partial response), with an ORR of 34%. Eleven patients (34%) achieved SD (stable disease), and ten patients (31%) achieved PD (progression disease), with a DCR of 69%. The progression-free rates (PFRs) at three and six months were 81% and 69%, respectively. The median PFS time was 8.2 months. The hematologic and non-hematologic toxicities were manageable. The most common grade 3 and 4 adverse events were febrile neutropenia (9%), leukopenia (19%), thrombocytopenia (3%), anemia (6%), anorexia (6%), vomiting (3%), and hypertension (6%). The combination therapy was generally well tolerated. Conclusion Our study suggests that chemotherapy combined with anlotinib plus anlotinib maintenance therapy had good efficacy and resulted in more favorable survival with good tolerance among patients with advanced/metastatic STS. © 2020 Wang et al.Specific tyrosine-kinase inhibitors (TKIs) are widely used for the treatment of non-small-cell lung cancers with anaplastic lymphoma kinase (ALK) translocations. However, most treated patients eventually develop resistance to the TKIs. The histological transformation into small cell carcinoma is well known to be the underlying mechanism for acquired resistance; however, transformation to squamous cell carcinoma is extremely rare. We, herein, report a case of ALK rearrangement-positive adenocarcinoma that transformed to squamous cell carcinoma after administration of alectinib, and was found to be resistant to ceritinib. © 2020 Kaiho et al.Purpose Previous studies have reported that FOXO6 is highly expressed in hepatocellular carcinoma (HCC) tissues and is associated with the prognosis of HCC patients. However, little research has been carried out to explore the role of FOXO6 in glycolysis of HCC cells and paclitaxel resistance. Today, along with the increasing incidence and mortality of HCC, chemotherapy resistance of HCC also poses a serious challenge. Therefore, this study was set out to investigate the effect of FOXO6 on glycolysis and cytotoxicity of paclitaxel in HCC cells and
