This study examined which signaling pathways mediate the regulatory effects of AKR1C3 on radioresistance in esophageal cancer cells. Methods: AKR1C3 protein expression was compared in patient tissue samples, and AKR1C3-silenced KYSE170R cells were generated. Radiosensitivity was assessed by colony formation, reactive oxygen species (ROS) by flow cytometry, and pathway proteins by Western blotting. Results: AKR1C3 was higher in radioresistant tissues; silencing increased radiosensitivity and ROS while altering ERK1/2, JNK, and AKT phosphorylation. Conclusions: AKR1C3 likely mediates radioresistance via MAPK and AKT signaling.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/aldo-keto-reductase-family-1-member-c3-mediates-radioresistance-of-esophageal-cancer-cells-through-suppressing-mapk-and-akt-signaling/332584/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/aldo-keto-reductase-family-1-member-c3-mediates-radioresistance-of-esophageal-cancer-cells-through-suppressing-mapk-and-akt-signaling/332584.png","ImageObject",300,407,{"name":42,"@type":43},"Riley","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-29","2026-09-21",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",7,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What role does AKR1C3 play in esophageal cancer radioresistance?","Question",{"text":63,"@type":64},"AKR1C3 is associated with radioresistance in esophageal cancer.

This study aimed to investigate the signaling pathways that mediate the regulatory role of AKR1C3 in the radioresistance of esophageal cancer cells.  \nMethods The protein level s ofAKR1C3 in cancer tissue samples were compared between patients with radiosensitive and radioresistant esophageal cancer using immunohistochemical staining. AKR1C3-silenced stable KYSE170R esophageal cancer cells (KY170R-shAKR1C3) were established. Colony formation assay was employed to evaluate the radiosensitivity of cancer cells, while flow cytometry analysis was utilized to quantify reactive oxygen species (ROS) production in these cells. Additionally, Western blotting was conducted to determine protein expression levels.  \nResults AKR1C3 protein exhibited significantly higher expression in radioresistant cancer tissue samples compared to radiosensitive samples. AKR1C3 silencing promoted radiosensitivity and ROS production of KYSE170R cells. At  \n32 h after X-ray radiation, the levels of total and phosphorylated ERK1/2, JNK, and AKT proteins were significantly elevated in KYSE170R-shAKR1C3 cells compared to untransfected KYSE170R cells. The inhibitor of AKR1C3 remarkably enhanced the radiosensitivity of KYSE170R cells. Conversely, treatment with either a MEK inhibitor or an AKT inhibitor significantly increased the radioresistance of KYSE170R-shAKR1C3 cells.  \nConclusions Our results suggest that AKR1C3 mediates radioresistance of KYSE170R cells possibly through MAPK and AKT signaling.  \nKeywords Radiosensitivity, Esophageal cancer, Aldo-keto reductase family 1 member C3, ERK, JNK  \n†Wei Xiong, Ya Xie, Dong Wang and Xiaozhi Huang contributed equally to this work.  \n*Correspondence: Jingwu Li [798151504@qq.com](798151504@qq.com)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2024.
