Chemotherapy is one of the most important strategies for the treatment of pancreatic cancer; however, the chemoresistance exhibited by pancreatic cancer cells is a leading cause of chemotherapy failure. It has been reported that overexpression of ALDH1A1 significantly correlates with poor prognosis and tumor aggressiveness, and is clinically associated with chemoresistance. Additionally, ALDH1A1 may serve as a novel regulator for the diagnosis and prognosis of cancer resistance. In particular, ALDH1A1 can promote cancer progression by facilitating the manifestation of cancer stem cell properties. However, the molecular mechanism by which ALDH1A1 clinically regulates the development of chemoresistance, and its role in prognosis and cancer stem cells, including pancreatic cancer stem cells, remain unclear. Therefore, the current review aims to summarize the clinical functions of ALDH1A1 as a novel regulator of chemoresistance, prognosis, and cancer stem cell development in pancreatic cancer.  \nKeywords  \naldehyde dehydrogenase-1A1, chemoresistance, pancreatic cancer cells, cancer drug resistance, cancer stem cells  \nReceived August 15, 2024.

As a result, it is often detected at a late stage, and is associated with high mortality, primarily due to lack of early biomarkers for detection and the resistance to traditional therapeutic regiments such as chemotherapy and radiotherapy.1-3 Several biomarkers have been proposed for the early detection of pancreatic cancer, including serum carbohydrate antigen (CA19-9),4,5 carcinoembryonic antigen  \n(CEA),5 methylated DNA biomarkers (CD1D, KCNK12, CLEC11A, NDRG4, IKZF1, and PKRCB), and mutant KRAS.6 However, these markers still have significant  \n1 Laboratory Center, Hanoi University of Public Health, Hanoi, Vietnam 2Laboratory Department, Yenphong Medical Center, Bacninh, Vietnam 3Laboratory Department, Bacgiang General Hospital, Bacgiang, Vietnam 4Pathology Department, Ducgiang General Hospital, Hanoi, Vietnam 5Faculty of Biomedical Sciences, Phenikaa University, Hanoi, Vietnam  \nCorresponding Author:  \nHong-Quan Duong, Laboratory Center, Hanoi University of Public Health, 1A Duc Thang, Duc Thang, North Tu Liem, Hanoi 100000, Vietnam.  \nEmail: [dhq@huph.edu.vn](dhq@huph.edu.vn)  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative Commons  \nAttribution-NonCommercial 4.0 License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)) which permits non-commercial use,  \nreproduction and distribution of the work without further permission provided the original work is attributed as sp","cbCaip4M5eGOks2F","https://ap.wps.com/l/cbCaip4M5eGOks2F","pdf",717479,"English","# Introduction\n## Pancreatic cancer burden and biomarker limitations\n# ALDH1A1 biology and relevance to therapy resistance\n## ALDH isoenzymes and ALDH1A1 substrate specificity\n## Associations between ALDH1A1 expression and disease progression\n# ALDH1A1 as a regulator of chemoresistance and cancer stem cell development\n## Clinical functions and prognostic implications","[{\"question\":\"What role does ALDH1A1 play in pancreatic cancer chemoresistance?\",\"answer\":\"ALDH1A1 overexpression correlates with poor prognosis and tumor aggressiveness and is clinically associated with chemoresistance in pancreatic cancer cells.\"},{\"question\":\"Why is pancreatic cancer difficult to detect early and treat effectively?\",\"answer\":\"It is characterized by aggressiveness and metastatic potential, often has no early symptoms, is diagnosed late, and lacks early biomarkers, contributing to high mortality and therapy resistance.\"},{\"question\":\"What is the focus of the review regarding ALDH1A1?\",\"answer\":\"The review summarizes ALDH1A1’s clinical functions as a regulator of chemoresistance, prognosis, and cancer stem cell development, particularly in pancreatic cancer.\"}]","Aldehyde Dehydrogenase-1A1 (ALDH1A1) - The Novel Regulator of Chemoresistance in Pancreatic Cancer Cells | PDF",1789999595,25]
