Bioinformatics investigation of the prognostic value and mechanistic role of CD9 in glioma. (PubMed, Sci Rep)
Further, several marker genes, such as VEGFR-2, TGF-β1, CASP1 and PI3K, were down regulated in CD9 knockdown cell lines and up regulated in CD9 overexpression cell lines, compared with control cell line. This study preliminarily explores the role of CD9 in gliomas and its prognostic value, providing new insights for personalized treatment strategies in glioma therapy.

Resting natural killer cells promote the progress of colon cancer liver metastasis by elevating tumor-derived stem cell factor. (PubMed, Elife)
Functional experiments finally revealed that NK cells exhibited tumor-activating characteristics by promoting the dissociation of SCF (stem cell factor) on the tumor cells membrane depending on cell-to-cell interaction, as the supernatant of the co-culture system enhanced tumor progression. In summary, our findings revealed resting NK cells exhibited a clinical relevance with CCLM, which may be exploited for novel strategies to improve therapeutic outcomes for patients with CCLM.

Breast Cancer With Release of Tumor Cells in Peripheral Blood Mimicking Acute Myeloid Leukemia. (PubMed, J Hematol)
The FC analysis of the peripheral blood allowed the rapid characterization of a non-hematological neoplastic cell population, circulating at unusually high frequency and mimicking an acute myeloid leukemia. The FC detection of CD45-negative cell populations in peripheral blood, bone marrow or lymph node aspirate should prompt the setup of an immunophenotyping panel including EpCAM, CD9, CD56 and CD117, to allow for a rapid and accurate identification of ectopic malignant epithelial cells.

CD9 shapes glucocorticoid sensitivity in pediatric B-cell precursor acute lymphoblastic leukemia. (PubMed, Haematologica)
Here, we showed that CD9- BCP-ALL cells were preferentially resistant to prednisone and dexamethasone over other standard cytotoxic agents. Importantly, the MEK inhibitor trametinib exhibited higher synergy with GCs against CD9- than CD9+ lymphoblasts to reverse drug resistance in vitro and in vivo. Collectively, our results elucidate a previously unrecognized regulatory function of CD9 in GC sensitivity, and inform new strategies for management of children with resistant BCP-ALL.

The Tetraspanin CD9 Shapes Glucocorticoid Sensitivity in Pediatric B-Precursor Acute Lymphoblastic Leukemia (ASH 2023)
Ex vivo drug sensitivity profiling to prednisone (Pred) and dexamethasone (Dex) was performed on 6 BCP-ALL cell lines and 18 patient samples with differential CD9 expression. This study provides a definitive linkage of CD9 with GC sensitivity in childhood BCP-ALL mediated through a NR3C1-independent mechanism. CD9- cases could be prone to trametinib combination therapy, whereas CD9+ cases might need a third drug such as ruxolitinib to counteract GC resistance.

Epigenetic Silencing of CD9 Shapes a New Mechanism to Render Differentiation Block and Immune Evasion in Pediatric Acute Myeloid Leukemia (ASH 2023)
Exposure of CD9- AML cell lines (n=8) or samples (n=9) to the histone deacetylase inhibitor panobinostat significantly elevated CD9 mRNA and protein expression (3.1-32.2-fold, P<0.05), restored activating histone acetylation marks (4.1-41.6-fold, P<0.05), and potently suppressed myeloblast proliferation ex vivo (median IC50: 21.4 nM)...In NSG mice, co-transplantation of human PBMCs mounted an effective immunity against CD9+ but not CD9- AML (MV4-11 and MOLM-13, P<0.05), concomitant with a robust bone marrow infiltration of cytotoxic T cells. Taken together, our data provided molecular, cellular and clinical evidence showing the plausible function of CD9 as a key driver intertwining monocytic differentiation and immune recognition in pediatric AML, and inspired a new combinatorial epigenetic/immunotherapy for this rare but aggressive malignancy.

This work presents the composition of the CD9 protein web in BCP-ALL, revealing homogenous and heterogeneous partners across the leukemia subtypes. We also provide definitive evidence showing that CD9 binds to and regulates CD38 activity to mediate leukemia progression, representing the first universal protein partner being identified to have a functional consequence in BCP-ALL, thereby providing a mechanistic basis to support the development of CD9-targeted therapies for this life-threatening malignancy.

Single-cell trajectory analysis reveals a CD9 positive state to contribute to exit from stem cell-like and embryonic diapause states and transit to drug-resistant states. (PubMed, Cell Death Discov)
Importantly, CD9 knockdown or blockade sensitized SUM149 to JQ1 in vivo by trapping cells in the SCLED state and limiting transit to resistant cell states. Thus, CD9 appears to be critical for the transition from a SCLED state into treatment-resistant cell states and warrants exploration as a therapeutic target in basal-like breast cancer.

Novel NUTM1 Fusions in Relapsed/Refractory Acute Myeloid Leukemia with Monocytic Differentiation (Selected for Oral Presentation, O-03-04) (AMP Europe 2023)
Here we report two AML patients with monocytic features that presented with relapsed/refractory (R/R) disease with no response either to transplant or navitoclax/venetoclax plus decitabine therapy. The first case has been transplanted; however, it relapsed 120 days post-transplant with a chimerism of 20%. The second case has shown R/R AML since the initial diagnosis. Additionally, the novel AVEN::NUTM1 fusion case reported in the literature, relapsed post-chemotherapy and was minimal residual disease positive 3 months after transplant with DNA sequencing detecting IDH1 and RUNX1 mutations.
