Description

The hematological system experiences clonal malignant proliferation of myeloid progenitors in Acute Myeloid Leukemia (AML), which leads to a buildup of leukemic blasts in the Bone Marrow (BM) and blood. AML is a clinically and genetically diverse disease. Because the U.S. Food and Drug Administration (FDA) has approved several new drugs for AML, including Glasdegib, Venetoclax, and others, the traditional chemotherapy combined with Hematopoietic Cell Transplantation (HCT) as a fundamental strategy for AML has changed significantly in recent years. Despite the aforementioned, AML patients continue to have low overall survival rates due to disease persistence and recurrence. After receiving first-line rigorous treatment, about 20%–30% of patients never reach Complete Remission (CR), a best course of action is still up for debate since this suggestion lists 30% of AML patients as having intermediate risk, many of whom do not have prognostic nuclear abnormalities or gene alterations. As a result, there is still room for improvement in the prognosis assessment and risk categorization of AML patients. Given that patients with relapsed AML respond less to treatment and have a worse overall survival, the prevalence of AML recurrence continues to be one of the biggest issues with AML treatment. To screen relapse-related genes and investigate their impact on the prognosis of AML patients, 1298 adult AML patients are selected from the TCGA and GEO datasets, including those with denovo AML and relapsed AML patients and 50% relapse after CR is attained. With increasing knowledge of the pathogenesis of AML, cytogenetic abnormalities and gene mutations have been used for risk stratification and prognosis assessment, in addition to the introduction of new drugs that have a significant impact on the treatment landscape for AML. The updated risk stratification by genetics is included in the 2017 edition of the European Leukemia Net (ELN) recommendations for the diagnosis and treatment of AML in adults. For instance, due to their distinct relationships with risk, monosomal karyotype, RUNX1, ASXL1, and TP53 mutations have been added as characteristics of the adverse-risk group. Pathogenesis of diverse forms of lymphomas is significantly influenced by cytokine-cytokine receptor interaction. In order to activate NF-kappa B, MAP kinases, and IRFs, which control the transcription of genes producing type I interferon and other inflammatory cytokines, Toll-Like Receptors (TLRs) and RIG-ILike Receptors (RLRs) are protective immunological guardians.

Previous research has established the link between TLRs and hematopoietic damage, which results in enhanced HSC proliferation and a preference for myeloid cell differentiation, strengthening the development of hematological malignancies and bone marrow failure. This could be as a result of the release of pro inflammatory cytokines, which may create a milieu supportive to cancer. Th17 cells have been identified as a subset of Th cells that exhibit pro inflammatory and tumor-promoting properties in many cancer types. The TNF-signaling pathway has been linked to the pathophysiology of a wide range of human disorders, including diabetes, cancer, and many inflammatory diseases. It is a key modulator of apoptosis, inflammation, and immunity.

Research has also shown that controlling phospholipase activity promotes the growth of tumors. Diethylene glycol play a significant role in creating a microenvironment that is favorable for the growth of tumor cells. The study discovered that the majority of the genes linked to the recurrence of AML are grouped in the immune correlation pathways through the enrichment of DEGs. Previous studies have also shown that the immune response is crucial to the development and spread of different malignancies, and immunotherapy and targeted therapy are now recognized as two of the most important treatments for tumors, along with chemotherapy. As a result, the CIBERSORTx algorithm was employed in this study to estimate the proportion of 22 TIIC subsets from AML transcriptomes from the OHSU and GSE134589 databases, and to reveal distinct patterns of TIICs in initial and recurrent AML as well as the associations between various immune cell subsets and clinical outcomes.
