- The present study aimed to investigate the effects of microRNA (miR)‑5590‑3p on the biological functions of hepatocellular carcinoma (HCC) cells through the homeobox B2 (HOXB2)/MYC axis. The expression levels of miR‑5590‑3p, HOXB2 and MYC were measured in HCC tissues and cell lines, and the relationships between miR‑5590‑3p, HOXB2, and the clinicopathological characteristics and prognosis of patients with HCC were analyzed. The Cell Counting Kit‑8 assay assessed cell proliferation, flow cytometry measured apoptosis rate, and the Transwell and wound healing assays evaluated the invasive and migratory abilities of cells. The targeting interactions between miR‑5590‑3p and HOXB2, and between HOXB2 and MYC were assessed. In addition, a subcutaneous HCC xenograft model was established to assess the effects of miR‑5590‑3p on tumor growth. The results revealed that miR‑5590‑3p expression was downregulated in HCC tissues and cells, whereas HOXB2 and MYC expression were upregulated. Notably, low miR‑5590‑3p expression and high HOXB2 expression were both associated with a poor prognosis in patients with HCC. miR‑5590‑3p directly targeted and suppressed HOXB2, whereas HOXB2 promoted MYC transcription. Furthermore, downregulation of miR‑5590‑3p enhanced the invasion, migration and proliferation of Huh7 cells, and reduced their apoptotic rate. By contrast, miR‑5590‑3p overexpression or HOXB2 silencing decreased invasion, migration and proliferation, while increasing apoptosis. Moreover, HOXB2 overexpression reversed the inhibitory effect of miR‑5590‑3p upregulation on HCC cell proliferation. HOXB2 appeared to promote Huh7 cell proliferation and motility through MYC transcriptional activation, whereas miR‑5590‑3p overexpression suppressed tumor growth . In conclusion, miR‑5590‑3p may inhibit HCC cell proliferation and motility, and induce apoptosis by targeting HOXB2 and suppressing MYC transcription. - Source: PubMed

Li BinZhou Lin - The protein-protein interaction between menin and KMT2A (histone lysine methyltransferase 2A) plays a critical role in acute leukemia with KMT2A rearrangements, nucleophosmin 1 (NPM1) mutations and nucleoporin 98 rearrangements, and represents an emerging opportunity for therapeutic intervention. Here, we report development and comprehensive evaluation of the activity of ziftomenib as an orally bioavailable, highly potent and selective small molecule inhibitor of the menin-KMT2A interaction. In leukemia cells and primary patient samples with the menin-KMT2A dependency, ziftomenib profoundly inhibited proliferation, reduced clonogenic potential and induced differentiation, which was associated with strong downregulation of the menin-KMT2A target genes, including MEIS1, HOXA9 and HOXB2. In xenografts and patient-derived xenograft models of KMT2A-rearranged leukemia, ziftomenib induced leukemia regression or reduced leukemia burden, accompanied by a pronounced reduction of the menin-KMT2A target genes. We next assessed ziftomenib against four MEN1 (gene encoding menin) mutants (T349M, M327I, G331R, G331D) associated with clinical resistance to another menin inhibitor revumenib. Ziftomenib retained anti-leukemic activity against T349M mutant cells and demonstrated low-nanomolar potency (GI50≤25 nM) against G331R cells, despite several-fold reduced potency relative to MEN1 wild-type cells, whereas M327I and G331D mutants were resistant. The crystal structures of ziftomenib in complex with menin wild-type, T349M or G331R mutants revealed a similar binding mode of ziftomenib to these menin variants, rationalizing potent inhibitory activity towards these mutants. Ziftomenib has recently received FDA approval for adult patients with NPM1-mutated acute myeloid leukemia and continues to be evaluated clinically in leukemias with NPM1 or KMT2A alterations, both as monotherapy and in combinations. - Source: PubMed

The objective of this study is to identify biomarkers that may be linked to sarcopenia, examine how these biomarkers correlate with immune cell infiltration, and investigate the genes that exhibit a causal relationship with sarcopenia. - Source: PubMed

METHODS: Public datasets and online platforms (PrognoScan, GEPIA2, TIMER, and Kaplan–Meier Plotter) were integrated to evaluate HOXB2 expression, survival outcomes, and correlations with tumor-infiltrating immune cell estimates in CRC and LGG. Associations between HOXB2 and immune marker genes were further assessed. In vitro, HOXB2 expression and biological effects were examined in glioma cells and normal brain cells using RT-qPCR, CCK-8 proliferation assays, Transwell invasion assays, and Western blotting. HOXB2 knockdown was additionally evaluated in the CRC cell line HT-29 using CCK-8, Transwell invasion assays, and Western blotting. RESULTS: Across three CRC cohorts (GSE17536, GSE17537, and GSE14333), higher HOXB2 expression was significantly associated with poorer overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS). In LGG, higher HOXB2 expression was associated with worse OS (HR = 1.8, P = 0.00084) and DFS (HR = 1.5, P = 0.014). TIMER analyses indicated that HOXB2 expression was positively correlated with estimated infiltration levels of B cells, CD4⁺ and CD8⁺ T cells, macrophages, neutrophils, and dendritic cells in colon adenocarcinoma (COAD), rectum adenocarcinoma (READ), and LGG, and was also correlated with marker genes related to tumor-associated macrophages, regulatory T cells, and exhausted T cells. In vitro, HOXB2 expression was higher in glioma cells than in normal brain cells; HOXB2 knockdown reduced glioma cell proliferation and invasion and was accompanied by a decreased p-P65/P65 ratio. In HT-29 cells, HOXB2 knockdown similarly suppressed proliferation and invasion, and Western blotting confirmed effective HOXB2 downregulation. CONCLUSIONS: Elevated HOXB2 expression is associated with adverse prognosis and with immune infiltration-related signatures in COAD, READ, and LGG. Together with in vitro findings, these results support HOXB2 as a potential prognostic biomarker and suggest a link between HOXB2 expression, immune-related features, and NF-κB-associated signaling; further pathway-focused and in vivo studies are needed to clarify underlying mechanisms and causality. - Source: PubMed

Liu ZhenruiWen PuqiaoLiao YuxuanZhou DaweiWang HongyiXu RuofanZhang Zhen - To investigate the effect of SHP2 on the STAT3/TET3/HOXB2 signaling pathway in osteosarcoma, and its role in the proliferation, migration and invasion of osteosarcoma cells. First, bioinformatics analysis was used to identify relevant expressed genes. In vitro experiments, the expression levels of SHP2, p-STAT3, TET3, HOXB2, c-Myc, NANOG, NUSAP1 proteins in 143B cells and MG63 cells were detected by Western blot assay. The levels of TET3 and HOXB2 were detected by immunofluorescence double staining. Cell proliferation was detected by plate clone formation and CCK-8 assay. Cell migration was detected by scratch assay, and cell migration and invasion were detected by Transwell assay. Overexpression of SHP2 promotes osteosarcoma proliferation by upregulating STAT3, TET3 and HOXB2 proteins. VEGF activates RTK receptors and induces SHP2 autophosphorylation, which in turn activates STAT3 and enhances TET3 synthesis. TET3 then promotes HOXB2 transcription through demethylation. HOXB2 further upregulate the expression of c-Myc, NANOG and NUSAP1, ultimately driving the proliferation, migration and invasion of osteosarcoma and promoting tumor progression. This study confirmed that SHP2 promotes the proliferation, invasion and invasive ability of osteosarcoma cells by activating the STAT3/TET3/HOXB2 pathway, providing a new strategy for targeted treatment of osteosarcoma. - Source: PubMed
