Pharmacological effects of koumine on acute lung injury in septic mice: From in vivo experiments and network pharmacology studies. (PubMed, Biochem Biophys Res Commun)

Network pharmacology analysis showed that 52 putative targets were relevant, and SLC6A4, HTR3A, JAK2 and JAK3 were the key targets. GO and KEGG pathway enrichment analysis showed that the related mechanisms involved neuroactive ligand-receptor interaction, calcium signaling pathway, serotonergic synapses, cholinergic synapses, etc. In summary, this study confirmed the potential therapeutic effect of koumine in sepsis induced ALI, suggesting its development prospect as a novel candidate drug for ALI, and providing data support.

The Innate Immune System Surveillance Biomarker p87 in African Americans and Caucasians with Small High-Grade Dysplastic Adenoma [SHiGDA] and Right-Sided JAK3 Colon Mutations May Explain the Presence of Multiple Cancers Revealing an Important Minority of Patients with JAK3 Mutations and Colorectal Neoplasia. (PubMed, Gastrointest Disord (Basel))

Thus, this pilot study suggests that the reduction in p87 in the right colon is possibly correlated with JAK3 mutations. If confirmed, JAK3 mutations, known to be associated with immune aberrations, may provide a mechanistic explanation for the lack of a p87 (protein 87 kilodaltons) field in some patients with HGD polyps who might benefit from possible intervention such as more intensive screening. Limited microbiome studies were also performed on two patients with familial cancer syndromes and these compared favorably with controls available from the literature.

Ruxolitinib combined with venetoclax and azacitidine in the treatment of refractory T-ALL patients with JAK1, JAK3, and STAT5B gene mutations: a case report and literature review (PubMed, Zhonghua Xue Ye Xue Za Zhi)

Notably, pleural effusion and mediastinal mass significantly improved the post-chest cavity infusion of dexamethasone combined with etoposide at the same stage. The patient also underwent allogeneic hematopoietic stem cell transplantation upon achieving bone marrow remission and was followed up until January 2024. Ruxolitinib combined with venetoclax and azacytidine has shown promising efficacy and safety in treating refractory T-ALL harboring the JAK1, JAK3, and STAT5B mutations, providing a novel therapeutic approach for such patients.

Keratinocytes present Staphylococcus aureus enterotoxins and promote malignant and non-malignant T cell proliferation in cutaneous T cell lymphoma. (PubMed, J Invest Dermatol)

In conclusion, we show that, upon exposure to patient-derived S. aureus and SE, keratinocytes stimulate IL-2Rγ/JAK3-dependent proliferation of malignant and non-malignant T-cells in an environment with non-malignant T-cells. These findings suggest that keratinocytes in the TME play a key role in S. aureus mediated disease activity in CTCL.

Treatment patterns, clinical outcomes and gene mutation characteristics of hepatitis B virus-associated mantle cell lymphoma. (PubMed, Hematol Oncol)

The HD-AraC (high-dose cytarabine) regimen was the main first-line induction regimen for younger HBsAg+ patients, and cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) were used for elderly patients. HBsAg seropositivity was associated with a significantly shorter PFS than HBsAg seronegativity when patients were treated with rituximab or CHOP-based regimens...Among the 74 patients who underwent targeted deep sequencing (TDS), the nonsynonymous mutation load of HBsAg+ MCL patients was greater than that of HBsAg- MCL patients. HDAC1, TRAF5, FGFR4, SMAD2, JAK3, SMC1A, ZAP70, BLM, CDK12, PLCG2, SMO, TP63, NF1, PTPR, EPHA2, RPTOR and FIP1L1 were significantly enriched in HBsAg+ MCL patients.

Idiopathic erythrocytosis: a germline disease? (PubMed, Clin Exp Med)

We identified recurrent germline variants in 42 (75%) patients occurring mainly in JAK/STAT, Hypoxia and Iron metabolism pathways, among them: JAK3-V722I and HIF1A-P582S; a high fraction of patients (48.2%) resulted also mutated in homeostatic iron regulatory gene HFE-H63D or C282Y. By generating cellular models, we showed that JAK3-V722I causes activation of the JAK-STAT5 axis and upregulation of EPAS1/HIF2A, while HIF1A-P582S causes suppression of hepcidin mRNA synthesis, suggesting a major role for these variants in the onset of IE.

The JAK3 mutation reveals oncogenic potential and resistance to ruxolitinib. (PubMed, Mol Carcinog)

Notably, JAK3 not only promotes constitutive activation of the JAK/STAT pathway in the absence of cytokines and growth factors, as is the case for other JAK3 mutations that have been functionally characterized as oncogenic, but also functions independently of JAK1 and IL2RG, resulting in high oncogenic potential as well as resistance to ruxolitinib. Our results indicate that ruxolitinib may not be efficient for future patients bearing the JAK3 mutation who instead may obtain greater benefits from treatments involving other pharmacological inhibitors such as tofacitinib.

Germline mutation in RUNX1 should be considered in pediatric patients with thrombocytopenia and/or abnormal platelet function and a hypocellular marrow with or without dysmegakaryopoiesis. Dysmegakaryopoiesis in the setting of RUNX1-FPDMM should not be overinterpreted as pediatric MDS without other supporting criteria such as MDS-defining cytogenetic/molecular abnormalities, multilineage dysplasia, or increased blasts. Patients with large deletions in RUNX1 may be missed on routine NGS testing hence proper germline testing in an experienced laboratory is recommended if suspicion is high.

Efficacy of Demethylated Drug Combine with Low Dose Chemotherapy in Juvenile Myelomonocytic Leukemia (ASH 2023)

All patients were given Demethylated drug in combination with low-dose chemotherapy, 10 patients decitabine at a dose of 20 mg/m2 for 5 days, supplemented with cytarabine (50-100 mg/m2×3~5 days), and /or etoposide (50 mg/m2×3~5 days), 6 patients Azacytidine at a dose of 75mg/m2 for 7 days combined with homoharringtonine 2mg/m2 for 5-7 days. Demethylated drug in combination with low-dose chemotherapy could reduce JMML patients' tumor burden, improve the general condition, and obtain a clinical response rate of 81.8% after 3 cycles therapy. Therefore, such a combination regimen could be used as a therapeutic option for JMML before HSCT.

Pax5 Heterozygosity Affects B-Cell Differentiation and Generates a Deregulated Precursor Population in the Bone Marrow (ASH 2023)

In summary, we deeply characterized how reduced Pax5 transcriptional activity in the BM generates a predisposed precursor B-cell environment, which is susceptibility for malignant transformation. These findings are important for understanding the molecular mechanisms to prevent or treat a significant proportion of childhood BCP-ALLs.

CD7 Chimeric Antigen Receptor T-Cell Therapy Bridging to Allogeneic Hematopoietic Stem Cell Transplantation Remarkably Improved Long-Term Disease-Free Survival in Refractory/Relapsed T-Cell Acute Lymphoblastic Leukemia/Lymphoma (ASH 2023)

Myeloablative conditioning regimens with either total body irradiation (TBI)/fludarabine (51, 56.7%) based or busulfan/fludarabine (39, 43.3%) based were applied...Cyclosporine, mycophenolate mofetil and short-term methotrexate were employed for graft-versus-host disease (GVHD) prophylaxis... Our study has demonstrated that CD7 CART followed by allo-HSCT has remarkably improved long-term DFS for chemotherapy-resistant T-ALL/LBL, and achieved comparable results in safety and efficacy with chemotherapy-sensitive disease post-transplant. Our study has also shown the profiles of somatic and germline gene mutations in r/r T-ALL/LBL, and identified some positive and negative impact factors for prognosis after transplant in this setting.

Case Report: Aggressive NK Cell Leukemia in a 58-Year-Old Female Patient - Use of an Individualized Treatment Approach with Venetoclax/Ruxolitinib (DGHO 2023)

First-line treatment consisted of polychemotherapy according to the SMILE protocol (methotrexate, dexamethasone, ifosfamide, etoposide phosphate, PEG-asparaginase), but the patient relapsed within three weeks. Salvage therapy was started according to the GMALL protocol with prephase therapy (cyclophosphamide and dexamethasone) followed by induction I (idarubicin, vincristine and dexamethasone)... ANKL is a rare and aggressive disease associated with a poor prognosis. In line with this, our patient did not show durable responses to polychemotherapy including MTX, L-asparaginase, alkylating agents, and anthracyclines. Despite post-remission treatment with allo-HSCT and a personalized medicine approach based on treatment guided by mutational analysis, the patient showed rapid progression and ultimately succumbed to the disease.

Intertumoral heterogeneity impacts oncolytic vesicular stomatitis virus efficacy in mouse pancreatic cancer cells. (PubMed, J Virol)

Also, we discovered that more VSV-permissive mouse PDAC cell lines harbor mutations in multiple important antiviral genes, such as TYK2, JAK2, and JAK3. Our study provides essential information about three model mouse PDAC cell lines and proposes a novel platform to study OV-based therapies against different PDACs in immunocompetent mice.

Genomic signatures and prognosis of advanced stage Chinese pediatric T cell lymphoblastic lymphoma by whole exome sequencing. (PubMed, Front Pediatr)

Although T-ALL and T-LBL both originate from precursor T-cells and are considered different manifestations of the same disease and the outcome of T-LBL is favorable when using T-ALL-based chemotherapy, there are differences in the gene distribution between T-LBL and T-ALL. It seems that the PI3K-Akt signaling pathway and the USP34 gene play important roles in T-LBL, but medicines targeting the USP34 gene or the PI3K-Akt pathway may be invalid.

JAK3 Y841 Autophosphorylation Is Critical for STAT5B Activation, Kinase Domain Stability and Dimer Formation. (PubMed, Int J Mol Sci)

Computational biophysics analysis linked Y841 phosphorylation to enhanced JAK3 JH1 domain stability across pH environments, as well as to facilitated complementary electrostatic JH1 dimer formation. Interestingly, Y841 is not limited to tyrosine kinases, suggesting it represents a conserved ubiquitous enzymatic function that may hold therapeutic potential across multiple kinase families.
