Background: Accumulating evidence suggests that mitochondrial fission and fusion events are imbalanced in cancer due to defective activity of their key regulators. In this study, we investigated the functional role of the E3 ubiquitin ligase Membrane-Associated Ring-CH-Type Finger 5 (MARCH5) in regulating cell growth, metabolic reprogramming and drug resistance in multiple myeloma (MM) through the negative regulation of the mitochondrial fusion driver mitofusin 2 (MFN2).
Methods: Cell viability and apoptosis were evaluated in MM cell lines or in co-culture with stromal cells using the CellTiter-Glo® Cell Viability Assay and Annexin V/7-AAD staining, respectively.

Background: Multiple myeloma (MM) is a hematological malignancy characterized by profound immunosuppression resulting from both disease-related mechanisms and treatment-induced immune dysfunction. This compromised immune status markedly increases susceptibility to infections, a leading cause of morbidity and mortality in MM patients. While vaccination represents a cornerstone of infection prevention, standard immunization strategies often yield suboptimal responses in this population.

Comorbidities and treatment-related logistics are increasingly recognized as key factors in treatment feasibility. Venetoclax-obinutuzumab (VO) has demonstrated efficacy in both fit and unfit patients in clinical trials, yet real-world data remain limited.

Cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies have revolutionized the treatment of cystic fibrosis (CF) by targeting the underlying protein defect. Investigating how elexacaftor/tezacaftor/ivacaftor (ETI) therapy affects interferon (IFN) signalling and inflammatory cytokine production in CF airway epithelial cells may clarify its role in alleviating the dysregulated innate immune response. Clinical efficacy was evaluated in 26 modulator-naive CF patients with at least one F508del mutation before and after 3 and 6 months of ETI treatment.

Lenalidomide remains the gold standard, as demonstrated in phase 3 trials, consistently showing superior survival compared to observation or placebo. However, both established and novel agents - such as thalidomide and pomalidomide, proteasome inhibitors (PIs), monoclonal antibodies (moAbs), and bispecific antibodies - have been investigated as alternatives to assess their efficacy and safety.

Chronic myeloid leukemia (CML) has undergone a transformation from a fatal disease to a chronic, manageable condition with the advent of tyrosine kinase inhibitors (TKIs), particularly imatinib. This shift has significantly improved survival rates, and for some patients, achieving deep molecular response (DMR) has made treatment-free remission (TFR) a feasible goal. However, the ability to sustain TFR remains a challenge, primarily due to the persistence of leukemia stem cells (LSCs), which are inherently resistant to TKIs and contribute to relapse after treatment cessation.

IGHV genes may also incorporate additional ongoing mutations, a phenomenon known as intraclonal diversification (ID). Here, through an original bioinformatic workflow for NGS data, we used the inverse Simpson Index (iSI) as diversity measure among IGHV sequences to dichotomize cases with different ID levels into ID (iSI ≥ 1.

Extensive studies have demonstrated that obesity significantly affects the risk, prognosis, and progression of various cancers, including multiple myeloma (MM). As an established modifiable risk factor for both MM and its precursor stages -monoclonal gammopathy of unknown significance (MGUS) and smoldering MM (SMM)- the association between obesity and disease onset has become a compelling area of research.

TP53-mutated acute myeloid leukemia (AML) remains one of the most treatment-resistant hematologic malignancies, with poor overall survival despite advancements in therapeutic strategies. The loss of functional p53 compromises DNA repair, apoptosis, and genomic stability, rendering both conventional and novel therapies largely ineffective. This review evaluates the efficacy of various treatment approaches, including intensive chemotherapy (IC), hypomethylating agents (HMAs), venetoclax-based regimens, and immune checkpoint inhibitors.

Herein, we investigate how mitochondrial dynamics, which controls mitochondrial fitness via coordinated fission and fusion events, shapes MM cell metabolism impacting growth, survival and drug sensitivity. We identify MFF (Mitochondrial Fission Factor), a pivotal driver of mitochondrial fragmentation, as being highly expressed in MM plasma cells bearing cytogenetic abnormalities predicting poor clinical outcome.

: In the randomized, phase-3 IKEMA trial, the triplet isatuximab, carfilzomib, and dexamethasone (IsaKd) demonstrated superior clinical benefit compared to those of carfilzomib and dexamethasone alone in patients with relapsed/refractory multiple myeloma after 1-3 prior treatments. : Our real-world, AENEID study aimed to evaluate the efficacy and safety of IsaKd in patients who relapsed after frontline lenalidomide treatment, poorly represented in the IKEMA trial. Specifically, in the present multicenter analysis, we enrolled eighty-two patients who received, between April 2022 and September 2024 and outside of clinical trials, at least one cycle of IsaKd as a second-line treatment at the first relapse after induction therapy, autologous stem cell transplantation (ASCT), and lenalidomide maintenance.

We conducted a multicenter retrospective study enrolling 120 octogenarian patients who received venetoclax (Ven) regimens in any line. Regarding efficacy, we found Ven to perform similarly to what is reported in younger patients with CLL, with an overall response rate of 91%, a complete response rate of 44%, and median progression-free survival of 44 months.

Advancements in the understanding of ITP pathogenesis have led to significant improvements in disease management through the use of both traditional immunosuppressive strategies and novel targeted therapies. However, a subset of patients remains refractory to treatment or achieves only transient benefits, underscoring the need for alternative therapeutic approaches. Bruton's tyrosine kinase (BTK) inhibitors have emerged as a promising strategy for autoimmune cytopenias, including ITP, due to their ability to modulate key immune pathways.
