BACKGROUND:Recurrence and metastasis are the main causes of disease deterioration in colorectal cancer (CRC) patients, yet efficient therapeutic strategies are lacking. Natural compounds for efficient antitumour therapeutics are becoming increasingly prominent. Kaempferol, one of the main components of flavonoids in plants, displays a variety of pharmacological activities. Our preliminary experiments suggested that kaempferol could inhibit CRC metastasis and is significantly associated with the β-catenin signalling pathway. Moreover, we also defined the regulatory roles of JMJD2C in β-catenin signalling in our previous work.PURPOSE:This study aims to reveal the mechanism by which kaempferol inhibits CRC progression and regulates the JMJD2C/β-catenin signalling pathway.METHODS:The migratory capabilities of CRC cells after kaempferol intervention were measured by scratch wound healing and transwell assays. Circ_0000345 knockdown CRC stable cell lines were generated by lentivirus infection. The possible mechanism of kaempferol on circ_0000345 was verified by molecular-protein docking and verification program cellular thermal shift assay (CETSA). A dual luciferase reporter gene assay was carried out for the targeting relationship among circ_0000345, miR-205-5p and JMJD2C. Fluorescence in situ hybridization (FISH) was performed to determine the expression of circ_0000345 in tumour tissues. A pulmonary metastatic model of CRC in vitro was built to assess the antimetastatic effect and mechanism of kaempferol in vivo.RESULTS:In vitro, kaempferol inhibits the ability to migrate of CRC cells by reducing the activation of the JMJD2C/β-catenin signalling pathway. MiR-205-5p is a key bridge for kaempferol to inhibit the expression of JMJD2C. The function of miR-205-5p is impeded by circ_0000345, which shows higher expression levels in human metastatic CRC tissues than nonmetastatic CRC tissues, and its formation is regulated by the RNA-binding proteins HNRNPK and HNRNPL. Mechanistically, kaempferol physically interacts with HNRNPK and HNRNPL to suppress JMJD2C by downregulating the expression of circ_0000345. In vivo, kaempferol suppresses CRC lung metastasis. Kaempferol inhibits the activation of JMJD2C/β-catenin signalling through reducing the expression of circ_0000345 in the CRC lung metastasis model.CONCLUSION:Circ_0000345 enhances activation of the JMJD2C/β-catenin signalling pathway through miR-205-5p to promote CRC metastasis. Kaempferol inhibits CRC metastasis through the circ_0000345-mediated JMJD2C/β-catenin signalling pathway, and this effect is influenced as a direct consequence of the binding of kaempferol with HNRNPK and HNRNPL. This provides promising therapeutic and/or adjuvant agents for advanced CRC and sheds light on the multifaceted role of phytomedicine in cancer.
Background: Recurrence and metastasis are the main causes of disease deterioration in colorectal cancer (CRC) patients, yet efficient therapeutic strategies are lacking. Natural compounds for efficient antitumour therapeutics are becoming increasingly prominent. Kaempferol, one of the main components of flavonoids in plants, displays a variety of pharmacological activities. Our preliminary experiments suggested that kaempferol could inhibit CRC metastasis and is significantly associated with the 8 -catenin signalling pathway. Moreover, we also defined the regulatory roles of JMJD2C in 8 -catenin signalling in our previous work. Purpose: This study aims to reveal the mechanism by which kaempferol inhibits CRC progression and regulates the JMJD2C/ 8 -catenin signalling pathway.

近年来,肺癌成为全球发病率、病死率急剧增长的癌症之一,是全球男性癌症相关死亡的主要原因,也是女性中仅次于乳腺癌的死亡原因[1].肺癌按病理类型可分为小细胞肺癌和非小细胞肺癌,其中非小细胞肺癌(Non-Small Cell Lung Cancer,NSCLC)最为常见,包括鳞癌、腺癌、大细胞癌,约占肺癌总数的80% ~ 85%[2],根据2015年第7版NCCN临床实践指南:对于大多数可耐受手术的NSCLC患者首选手术治疗.Ⅰ期、Ⅱ期和部分Ⅲa期可行手术完全性切除,Ⅰa完全切除术后患者5年生存率约为77%,Ⅲa期下降至23%[3],影响其生存率的主要原因是局部复发和远处转移[4].目前,铂类联合第3代细胞毒性药物的化疗方案仍然是临床上一线化疗的标准方案[5].目前已证实手术切除后的非小细胞肺癌术后辅助化疗是有益的[6],Ⅰb-Ⅲa期完全性切除后的NSCLC患者采取术后辅助化疗是标准方案,将患者的5年生存率提高5%[7].研究分析发现,Ⅱ期及Ⅲa期患者术后化疗的获益较明显[8-9],选择个体化的辅助化疗方案才是治疗成功的关键[10-11].
非小细胞肺癌是肺癌中最常见组织学类型,是发病率、死亡率均较高的恶性肿瘤。晚期非小细胞肺癌一线治疗后,为稳定病情在耐药产生前进行化疗药物或靶向药物维持治疗,取得了一定的进展,而化疗药物在维持治疗中维持治疗期的副反应发生率较高,靶向药物对EGFR野生型患者生存获益有待进一步研究。中医药维持治疗在提高生存质量、延长无进展生存期和/或总生存期方面可使患者获益。 Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. It is a malignant tumor with high incidence rate and mortality rate. After the first-line chemotherapy for advanced NSCLC, some progress have been made in maintenance treatment consists of either chemotherapy or targeted therapy to stabilize the condition, before the drug resistance. However, there is a high incidence of various side reactions of maintenance chemotherapy. Further studies are needed to confirm the survival benefit of the patient with wild type EGFR genes. Traditional Chinese medical treatment on maintenance therapy offers great benefits to patients that include improve quality of life and prolong progression free survival and/or overall survival.
