Despite epidermal growth factor receptor(EGFR)tyrosine kinase inhibitors(TKl)have shown remarkable efficacy in patients with EGFR-mutant non-small cell lung cancer(NSCLC),acquired resistance inevitably develops,limiting clinical efficacy.We found that TET2 was poly-ubiquitinated by E3 ligase CUL7^(FBXW11) and degraded in EGFR-TKI resistant NSCLC ells.Genetic perturbationof TET2 rendered parental cells more tolerant to TKI treatment.TET2 was stabilized by MEK1 phosphorylation at Ser 1107,while MEK1 inactivation promoted its proteasome degradation by enhancing the recruitment of CUL7^(FBXW11),Loss of TET2 resulted in the upregulation of TNF/NF-kB signaling that confers the EGFR-TKI resistance.Genetic or pharmacological inhibition of NF-kB attenuate the TKI resistance both in vitro and in vivo.Our findings exemplified how a cell growth controlling kinase MEK1 leveraged the epigenetic homeostasis by regulating TET2,and demonstrated an alternative path of non-mutational acquired EGFR-TKI resistance modulated by TET2 deficiency.Therefore,combined strategy exploiting EGFR-TKI and inhibitors of TET2/NF-κB axis holds therapeutic potential for treating NSCLC patients who suffered from this resistance. 展开更多

Radiotherapy remains one of the major treatments for non-small cell lung cancer(NSCLC)patients;whereas intrinsic or acquired radioresistance limits its efficacy.Nevertheless,most studies so far have only focused on acquired resistance.The exact mechanisms of intrinsic radioresistance in NSCLC are still unclear.A few studies have suggested that epithelial–mesenchymal transition(EMT)is associated with radioresistance in NSCLC.However,little is known about whether the abnormal expression of specific microRNAs induces both EMT and radioresistance.We previously found that miR-410 has multiple roles as an oncomiRNA in NSCLC.In this study,we revealed that miR-410 overexpression promoted EMT and radioresistance,accompanied by enhanced DNA damage repair both in vitro and in vivo.Conversely,knockdown of miR-410 showed the opposite effects.We further demonstrated that PTEN was a direct target of miR-410 by using bioinformatic tools and dual-luciferase reporter assays,and the miR-410-induced EMT and radioresistance were reversed by PI3K,Akt,and mTOR inhibitors or by restoring the expression of PTEN in NSCLC cells.In addition,we preliminarily found that the expression of miR-410 was positively correlated with EMT and negatively associated with the expression of PTEN in NSCLC specimens.In summary,these results demonstrated that miR-410 is an important regulator on enhancing both NSCLC EMT and radioresistance by targeting the PTEN/PI3K/mTOR axis.The findings suggest that miR-410-induced EMT might significantly contribute to the enhanced radioresistance.Therefore,miR-410 may serve as a potential biomarker or therapeutic target for NSCLC radiotherapy. 展开更多

Recent evidences show that nervous system acts as a crucial part of cancer microenvironment.Infiltration of nerve fibers into cancer microenvironment has an important active role in cancer progression.The stimulations of both cancer growth and metastasis by members of nervous system such as neurons and glial cells have been demonstrated.However,how the nervous system is built in cancer is largely unknown.Here we show that a fraction of cancer stem cells(CSCs)derived from patients with gastric carcinoma and colorectal carcinoma are capable of producing neurons that are involved in tumor neurogenesis and tumor growth.Cancer stem cell monoclone derived from a single cancer stem cell was able to generate neurons including sympathetic and parasympathetic neurons to take part in the nervous system in cancer tissues.Knocking down the neural cell generating capability of the human CSCs inhibited the growth of xenograft tumors in mouse model.Our data demonstrate that human CSCs are able to produce one of most important components in the cancer microenvironment that are required for cancer development and progression. 展开更多
