Despite the recent progresses in therapeutic methods, the mortality rate is still significantly high among lung cancer patients. A wide range of therapeutic methods including chemotherapy, radiotherapy, and surgery are used to treat lung cancer. Doxorubicin (DOX) and Paclitaxel (TXL) are widely used as the first-line chemotherapeutic drugs in lung cancer. However, there is a significant high percentage of DOX/TXL resistance in lung cancer patients, which leads to tumor recurrence and metastasis. Considering, the side effects of these drugs in normal tissues, it is required to clarify the molecular mechanisms of DOX/TXL resistance to introduce the efficient prognostic and therapeutic markers in lung cancer. MicroRNAs (miRNAs) have key roles in regulation of different pathophysiological processes including cell division, apoptosis, migration, and drug resistance. MiRNA deregulations are widely associated with chemo resistance in various cancers. Therefore, considering the importance of miRNAs in chemotherapy response, in the present review, we discussed the role of miRNAs in regulation of DOX/TXL response in lung cancer patients. It has been reported that miRNAs mainly induced DOX/TXL sensitivity in lung tumor cells by the regulation of signaling pathways, autophagy, transcription factors, and apoptosis. This review can be an effective step in introducing miRNAsas the non-invasive prognostic markers to predict DOX/TXL response in lung cancer patients.  \nKeywords Lung cancer, Paclitaxel, Doxorubicin, Chemo resistance, microRNA  \nBackground  \nLung cancer is the most frequent cancer and is responsible for the highest number of cancer-related deaths in the world [1]. Despite the recent progresses in molecular targeted therapies and surgical techniques, the overall 5-years survival rate is still around 15% for lung cancer patients [2]. Non-small cell lung cancer (NSCLC) is the most frequent lung tumor type accounting for 85% of  \n*Correspondence: Meysam Moghbeli [moghbelim@mums.ac.ir](moghbelim@mums.ac.ir)  \n1 Student Research Committee, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran  \n2 Department of Medical Genetics and Molecular Medicine, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran  \nall cases [1, 3]. Targeted drugs have efficient therapeutic benefits for NSCLC patients; however, drug resistance is a frequent challenge that is finally observed among a large proportion of NSCLC patients [4, 5]. Cisplatin, carboplatin, paclitaxel, docetaxel, gemcitabine, and pemetrexed are the frequently used chemotherapeutic options for NSCLC patients [6–8]. DNA-damaging factors are the most commonly used types of chemotherapeutic drugs [9, 10]. They prevent cell proliferation while induce cell death by the suppression of the double-strand breaks rejoining [11]. Microtubule targeting agents (MTAs) are also conventional chemotherapeutic drugs for NSCLC patients. They bind to microtubules at various sites to disrupt their dynamics and structure, resulting in cell cycle arrest and subsequent cell death [12,  \n© The Author(s) 2023.
