Summary: This article reviews the mechanisms of activating the NOTCH1 pathway in CLL, including NOTCH1 gene mutations and mutations in other pathways and physiological signals. Understanding the strategies through which CLL cells hijack NOTCH1 signaling is of great importance in designing targeted treatment strategies for CLL management.

Summary: In this study, the researchers evaluated the effects of an NF-kappa B inducing kinase (NIK) inhibitor, CW15337, on primary chronic lymphocytic leukemia (CLL) cells, CLL and multiple myeloma (MM) cell lines, and normal B- and T-lymphocytes. They found that CW15337 induced apoptosis and inhibited the non-canonical NF-kappa B signaling pathway, reversing BCL2 family-mediated resistance. The combination of CW15337 with fludarabine or ABT-199 showed synergistic cytotoxic effects.

Summary: Research into chronic lymphocytic leukemia has led to significant improvements in the assessment and treatment of patients, with designer drugs now successfully targeting tumor cells based on their biology. Classifying CLL into unmutated (U) and mutated (M) diseases based on the mutational status of IGHV sequences reveals distinct origins, biology, and clinical behaviors for each. Despite advances, challenges such as cell-escape strategies and immunosuppression remain, necessitating continued research into CLL biology.

Summary: This study compared the nucleosome positions in chronic lymphocytic leukemia (CLL) patients and healthy individuals, and found significant changes in nucleosome positioning in CLL. The spacing between nucleosomes was shortened, and changes in nucleosome occupancy were linked to chromatin remodeling and reduced DNA methylation. Nucleosome positioning can be used to classify CLL subtypes and monitor disease progression.

Summary: This study found that both coding and non-coding mutations in the NOTCH1 gene are associated with adverse prognosis in chronic lymphocytic leukemia (CLL) patients. These mutations are more commonly seen in patients without IGVH mutation, ZAP70 positivity, and CD38 positivity, and are associated with shorter time-to-first treatment.

Summary: The microenvironment of lymphoid organs plays a crucial role in the pathogenesis of chronic lymphocytic leukemia (CLL). The deficiency of pro-apoptotic and pro-oxidant adaptor p66Shc in CLL cells leads to enhanced accumulation and homing of leukemic cells in the lymphoid microenvironment. This deficiency causes a decrease in intracellular reactive oxygen species (ROS) production and an increase in the expression of chemokine receptors CCR2, CXCR3, and CCR7, which promote leukemic cell homing. The activation of the ROS-responsive transcription factor NF-kappa B is hampered in CLL cells with p66Shc deficiency, contributing to the overexpression of homing receptors and enhanced ability of these cells to survive in the lymphoid niche.

Summary: This study found that NOTCH1 activation is a negative prognostic factor in chronic lymphocytic leukemia (CLL) patients, significantly reducing Time To First Treatment (TTFT) regardless of NOTCH1 and IGHV mutation status. Activation of NOTCH2 and expression of JAGGED1 also influence clinical outcomes in this group, highlighting the need for further dedicated studies to refine CLL risk stratification using different components of the NOTCH network.

Summary: CLL is highly heterogeneous and may be treated with personalized therapy through targeting new mutations with drugs. Potential neurogenic locus notch homolog protein 1 (NOTCH1) signaling targeting mechanisms include secretase inhibitors and specific antibodies to block NOTCH ligand/receptor interactions. Studies have shown that newly discovered mutations and their signaling pathways play key roles in the course of the disease.

Summary: This review article discusses the dual role of the enzyme activation-induced cytidine deaminase (AID) in adaptive immunity and B-cell malignancies, emphasizing its pathological effects as a causative factor in leukemia and lymphomas. It summarizes the expression and function of AID in normal B lymphocytes, evaluates potential causes for AID expression in leukemic cells, and discusses its role in lymphomagenesis based on recent genomic landscape analyses of leukemia and lymphomas. The review also touches upon the correlation between AID off-target mutations and tumor-gene drivers in these cancers, and how these mutations could impact disease progression.

Summary: Cusatuzumab, a high-affinity anti-CD70 monoclonal antibody, has shown preliminary efficacy and tolerability when combined with azacitidine in patients with newly diagnosed AML ineligible for intensive chemotherapy. The recommended phase II dose of cusatuzumab was determined to be 10 mg/kg. Objective responses were achieved in 50% of patients, with a median duration of response of 4.5 months and a median overall survival of 11.5 months. The most common treatment-emergent adverse events were infections and hematologic toxicities. Further investigation of cusatuzumab combined with current standard-of-care therapy is ongoing.

Summary: Zanubrutinib has been approved for the treatment of various lymphoproliferative disorders, providing a significant breakthrough for patients who are resistant or relapse after recommended therapies. Due to the lack of systematic studies and comparative randomized clinical trials, the optimal use of zanubrutinib in approved indications presents challenges, especially in earlier stages of the disorders. This article presents the results of expert panel discussions aimed at identifying unmet clinical needs and proposing recommendations for the management of these needs.

Summary: Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults. Chemoimmunotherapy (CIT) was the commonest option for CLL treatment, but resistance to CIT has led to the use of targeted pathway inhibitors such as BTK and BCL2 inhibitors. However, acquired genetic lesions can cause resistance to these inhibitors.

Summary: This study aimed to investigate the long-term effects of previous immunization on evolving variants of SARS-CoV-2. The study found that patients who received the vaccine had fewer sequelae after COVID-19, as well as a lower incidence of respiratory complications and prolonged fatigue. This finding is important for the treatment and survival of cancer patients.

Summary: The assessment of cancer mutational profile is essential for patient management and treatment decisions. Liquid biopsy, specifically analyzing circulating tumor DNA (ctDNA), is an emerging approach that allows genotyping and monitoring of hematological malignancies during therapy and follow-up. It has been shown to capture unique genetic lesions that may be missed by tissue biopsy and predict patient outcomes. Additionally, ctDNA analysis has potential future applications in analyzing DNA fragmentation and epigenetic patterns. Several ongoing clinical trials are incorporating ctDNA analysis for personalized treatment in hematological malignancies.

Summary: This study explored the impact of TP53 gene mutations on the transcription of non-protein-coding genes, particularly focusing on the long non-coding RNA LINC01605. The researchers discovered that LINC01605 is directly regulated by mutant p53 and plays a role in the pro-migratory pathways of breast and ovarian cancer cell lines. The findings underscore the importance of non-coding RNAs in the network of mutant p53 in cancer cells.

Summary: The combination of venetoclax with hypomethylating agents significantly improved the outcome of AML patients unfit for intensive chemotherapy. However, real-world studies showed lower survival rates compared to clinical trials. Further research is needed to determine the cause of this discrepancy.
