Summary: Splenic marginal zone lymphoma (SMZL) is a rare lymphoproliferative disease affecting elderly patients. It primarily involves the peripheral blood, bone marrow, and spleen, while sparing the lymph nodes. The prolonged antigen stimulation of B lymphocytes and microenvironment play a crucial role in the development of SMZL. NOTCH2 and NFk-B signaling integration has been identified as the primary mechanism of neoplastic proliferation in SMZL. The prognosis of SMZL depends on individual risk factors and patients' health status.

Summary: Ocular adnexal marginal zone lymphoma (OAMZL) is a distinct type of lymphoma that occurs in tissues around the eyeball. The development of this lymphoma is associated with the constitutive activation of the NF-kappa B pathway, which may be caused by genetic alterations and epigenetic changes. The mucosa-associated lymphatic tissue (MALT) subtype is the most common subtype of lymphoma in the ocular adnexa.

Summary: NOTCH signaling, particularly NOTCH2, plays a critical role in the pathogenesis of splenic marginal zone lymphoma (SMZL). Frequent mutations of NOTCH2 in SMZL underscore its importance in the disease. While NOTCH signaling presents an appealing target for drug discovery in SMZL, previous efforts have not shown meaningful clinical benefit or faced safety concerns.

Summary: Recent investigations have shown that Waldenstrom macroglobulinemia (WM) exhibits an increased number of regulatory T cells (Tregs), and Tregs derived from patients with WM have a peculiar mRNA signature and functional phenotype. WM cells trigger significantly higher induction, expansion, and proliferation of Tregs compared to normal cells, especially in the context of CXCR4(C1013G)-mutated WM cells. CD40/CD40-ligand interaction is identified as an important axis supporting the interaction between WM cells and Tregs.

Summary: In this study, 4 variants affecting GALE were identified in 3 patients with severe thrombocytopenia. These patients exhibited giant and/or grey platelets, impaired platelet aggregation, and reduced secretion of alpha and dense granules. The study also revealed the critical role of GALE in the glycosylation and externalization of key proteins involved in platelet production and function, such as GPIb alpha-IX-V and mature beta 1 integrin.

Summary: This study aimed to investigate the potential beneficial effects of chronic docosahexaenoic acid (DHA) supplementation on restoring subcutaneous white adipose tissue (scWAT) plasticity in obese aged female mice. The results showed that the DHA-enriched diet reduced adipocyte size and reversed the upregulation of lipogenic genes induced by the high fat diet (HFD). DHA supplementation restored the increase of proinflammatory genes, switched scWAT macrophages profile to a healthier phenotype, and induced beige adipocyte markers in obese aged mice.

Summary: Protein glycosylation, including sialylation, is important for various biological processes. Carbohydrate conjugation to molecules and receptors is critical for normal hematopoiesis and platelet regulation. More than 200 enzymes are involved in proper glycosylation and sialylation. Genetic alterations in GNE, SLC35A1, GALE, and B4GALT can lead to syndromic manifestations, severe inherited thrombocytopenia, and hemorrhagic complications.

Summary: The GALE gene encodes an enzyme called UDP-galactose-4-epimerase, which plays a crucial role in the biosynthesis of glycoproteins and glycolipids. GALE-related disorders, such as galactosemia, are inherited in an autosomal recessive pattern and can lead to various complications. Recent studies have also linked GALE variants to severe thrombocytopenia and myelodysplastic syndrome.

Summary: Survival of multiple myeloma patients has improved over time with the development of new treatments, especially with the combination of novel agents. Using at least two novel agents in induction therapy significantly prolongs overall survival, even in older patients. This suggests that multiple myeloma has become a chronic and potentially curable disease in a subset of patients with the current therapeutic approaches.

Summary: Venetoclax combination therapies are becoming the standard of care in AML, but their efficacy in older/unfit patients is limited, highlighting the need for more effective therapies. Reactivating protein phosphatase 2A (PP2A) enhances venetoclax activity in AML cells by modulating BCL2 dependency and extracellular signal-regulated kinase signaling. Targeting PP2A increases the efficacy of venetoclax and azacitidine combination therapy in AML.
