Knockdown Wiskott-Aldrich syndrome protein family member 3(WASF3)inhibits colorectal cancer metastasis and sensitizes to cisplatin through targeting ZNF471

:Colorectal cancer(CRC)is a heterogeneous cancer,and many risk factors for colorectal cancer have been established.For CRC metastasis,tumor cell migration,adhesion as well as invasion are important processes.Wiskott-Aldrich syndrome protein family member 3(WASF3)is necessary for metastasis of various types of cancers.However,its role in CRC progression has not been fully elucidated.This study examined the in vitro functional roles of WASF3 in the CRC and explored the underlying molecular mechanisms.We used siRNA-WASF3 to gene silence WASF3 in colon cancer cell(HCT116)in vitro.The effects of WASF3 silencing on HCT116 cell apoptosis,proliferation,migration,as well as invasion were assessed by flow cytometry,CCK-8,and transwell assays.ZNF471 protein expressions were detected by immunofluorescence staining and RT-PCR.Moreover,the effects of ZNF471 were studied on a series of in vitro antitumor-promoting assays using HCT116.WASF3 knockdown expression using small interfering RNA(siRNA)ameliorated CRC cell proliferation,anchorage-independent growth,invasion,and metastasis.Furthermore,we observed that WASF3 contributed to upregulating the metastasis signaling pathway through inhibiting the expression of ZNF471.Our study suggests that targeting WASF3 signaling might be a novel therapeutic strategy for treating CRC.

磁压榨吻合技术治疗结直肠吻合及重建中的应用分析

回顾磁压榨吻合技术(magnetic compression anastomosis,MCA)治疗不同原因、不同类型肠道狭窄/闭锁实现肠道再通的案例,对MCA在结直肠吻合及重建中的临床应用进行分析探讨。4例患者2019年5月—2022年8月在西安交通大学第一附属医院及西北妇女儿童医院行结直肠MCA再通治疗。患者手术过程均顺利,实现肠道吻合再通,磁环排出时间为7~15 d,术后复查肠镜或造影提示吻合口完好。MCA可用于治疗不同原因、不同类型的结直肠狭窄及闭锁,也可用于辅助结直肠手术肠吻合。
