When the bone marrow microenvironment is exposed to immune suppression, leukemia cells result in the immune system's inability to eliminate malignant cells. To get a better understanding of the immunological possibilities associated with leukemia, clinical trials have explored immunotherapy techniques such as T cell activators, checkpoint inhibitors, antibody medicinal molecules, and cell treatments. One of the most important immune pathways is the programmed cell death 1 (PD1) protein. PD1 is expressed on the surface of T-cells and controls immune reactions. CD274, B7–H1, or PD-L1 are expressed by cells of the myeloid lineage, including macrophages, dendritic cells, effector CD8<sup>+</sup> T cells, tumor cells, and tumor-associated suppressor cells. Expression of PD-L1 molecule in cancer has been associated to worse prognosis and resistance to anti-cancer therapies in several malignancies. In this review, we update on the expression of PD-1 molecule in malignant hematological tumor cells and describe these molecules which inhibit the immune response to cancer cells. We provide an overview of the current scientific advancements, the significance of immunotherapy strategies and highlighting the potential for further development in targeting this specific molecule.

Various therapeutic methods have been established in combating the disease, and mesenchymal stem cells have come up as a crucial cell-based therapeutic strategy. Mesenchymal stem cells have been regarded as potential targets in various cancer types due to their immune-modulatory functions.

SCLC tumors are characterized by nearly universal biallelic inactivation of TP53 and RB1 genes and are classified into four molecular subtypes based on the expression of lineage-specific transcription factors. The integration of information encoded by the coding and non-coding genome has significantly improved our understanding of the contribution of various non-coding RNAs (ncRNAs), such as long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs), in the pathogenesis of SCLC. This has led to the concept of competing endogenous RNAs (ceRNAs) where the presence of the same miRNA response elements in one or more coding and ncRNAs may result in them competing for the same miRNA. Several studies have looked at the role of lncRNAs and circRNAs as ceRNAs by constructing ceRNA regulatory networks (ceRNETs).

Following the initial discovery that cellular pumps reliant on ATP were the root of chemotherapy resistance, more research has revealed the involvement of additional mechanisms, including increased drug metabolism, reduced drug entry, and compromised apoptotic pathways. Numerous projects have focused on MDR, and innumerable research has been conducted to better understand MDR and develop methods to mitigate its consequences. Multidrug resistance (MDR) is a key challenge in treating cancer. 90% of cancer-related fatalities are brought on by tumor metastasis and recurrence, which is possible with MDR. Drug resistance in cancerous cells is influenced by diverse internal and extrinsic variables, including genetic and epigenetic changes, drug efflux systems, DNA repair mechanisms, apoptosis, and autophagy. In this review paper, we list the potential hazards associated with cancer therapy in general, primarily multidrug resistance developing a theory for colorectal cancer in particular. We discussed the unique instance of multidrug resistance in colorectal cancer in malignancies generally and 5-fluorouracil, curcumin, and lipids as viable therapy options for the condition. The use of nanotechnology (mainly nanoparticles) has facilitated better <em>in vitro</em> as well as <em>in vivo</em> efficacy during preclinical phases, summarized below, allowing for a more thorough investigation of colorectal cancers and pancreatic carcinomas with their translation to following clinical trials.</p></div>","PeriodicalId":72083,"journal":{"name":"Advances in cancer biology - metastasis","volume":"10 ","pages":"Article 100114"},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667394024000017/pdfft?md5=e514d971e2f9aa115a596df3e74f0a55&pid=1-s2.0-S2667394024000017-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139487685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
