ABSTRACT

Nanotechnology has emerged as an effective approach to cancer treatment, including Colorectal Cancer (CRC). While conventional treatments, such as chemotherapeutic agents, are used to manage CRC, their efficacy can be improved using drug delivery systems that enhance their bioavailability and reduce side effects. Niosomes, polymeric nanoparticles, have shown promise as biocompatible vehicles that can transport hydrophilic and lipophilic molecules. This can result in reduced drug dosage and increased efficacy. This review examines the use of niosomal formulations as a delivery platform for treating CRC and provides practical insights into their clinical applications.

ABSTRACT

Late diagnosis is one of the main reasons for high mortality rates in cancer patients. Therefore, investigating the molecular mechanisms involved in tumor progression can improve the cancer diagnosis in the early stages of the tumor progression. MicroRNAs (miRNAs) have important roles in regulation of cell growth, proliferation, metabolism, and migration. Since, deregulation of miR-409 has been reported in a wide range of cancers, in the present review, we investigated the molecular mechanisms of miR-409 during tumor progression and invasion. It has been shown that miR-409 functions as a tumor suppressor in different tumor types. MiR-409 can reduce tumor cell proliferation, growth, and migration by regulation of signaling pathways, cellular metabolism, transcription factors, and cellular adhesion. This review can be an effective step in introducing miR-409 as a non-invasive marker in cancer patients.

ABSTRACT

Current interest in adhesion formation stems from its global impact on the function and quality of life, spanning a spectrum of subtle impairments to significant disabilities, based on the affected area and the extent of adhesion. Yet therapeutic agents are restricted to prophylactic anti-inflammatories, revision surgeries, and biological and physical techniques, none of which grant a decent outcome. Recent advancements in tissue- engineered biomaterials, drug delivery systems, and fabricating technologies such as nanoparticles, hydrogels, and weaving or braiding demonstrate potential for improved outcomes. However, none of the mentioned methods have reliable outcomes, thus this study aims to elucidate the mechanisms involved in the pathophysiology of tendon adhesion and post-surgical adhesion band formation (PSAB), with a closer look at inflammatory pathways stimulating the process. This article consolidates information on diverse therapeutic and prophylactic methods and cutting-edge technologies, aiming to provide a comprehensive update on this topic, and providing researchers an avenue for new and innovative ideas for further investigations.

ABSTRACT

Chemotherapy is widely used as one of the first line therapeutic methods in cancer patients. However, chemotherapeutic resistance is one of the most common problems in cancer patients, which leads to the therapeutic failure and tumor relapse. Considering the side effects of chemotherapy drugs in normal tissues, it is required to investigate the molecular mechanisms involved in drug resistance to improve the therapeutic strategies in cancer patients. Long non-coding RNAs (lncRNAs) have pivotal roles in regulation of cellular processes associated with drug resistance. LncRNAs deregulations have been frequently reported in a wide range of chemo-resistant tumors. Gemcitabine (GEM) as a nucleoside analog has a wide therapeutic application in different cancers. However, GEM resistance is considered as a therapeutic challenge. Considering the role of lncRNAs in the occurrence of GEM resistance, in the present review we discussed the molecular mechanisms of lncRNAs in regulation of GEM response among cancer patients. It has been reported that lncRNAs have mainly an oncogenic role as the inducers of GEM resistance through direct or indirect regulation of transcription factors, autophagy, polycomb complex, and signaling pathways such as PI3K/AKT, MAPK, WNT, JAK/STAT, and TGF-ß. This review paves the way to present the lncRNAs as non-invasive markers to predict GEM response in cancer patients. Therefore, lncRNAs can be introduced as the efficient markers to reduce the possible chemotherapeutic side effects in GEM resistant cancer patients and define a suitable therapeutic strategy among these patients.
