Abstract
Acute myeloid leukemia (AML) comprises a multifarious and heterogeneous array of illnesses characterized by the anomalous proliferation of myeloid cells in the bone marrow microenvironment (BMM). The BMM plays a pivotal role in promoting AML progression, angiogenesis, and metastasis. The immune checkpoints (ICs) and metabolic processes are the key players in this process. In this review, we delineate the metabolic and immune checkpoint characteristics of the AML BMM, with a focus on the roles of BMM cells e.g. tumor-associated macrophages, natural killer cells, dendritic cells, metabolic profiles and related signaling pathways. We also discuss the signaling pathways stimulated in AML cells by BMM factors that lead to AML progression. We then delve into the roles of immune checkpoints in AML angiogenesis, metastasis, and cell proliferation, including co-stimulatory and inhibitory ICs. Lastly, we discuss the potential therapeutic approaches and future directions for AML treatment, emphasizing the potential of targeting metabolic and immune checkpoints in AML BMM as prognostic and therapeutic targets. In conclusion, the modulation of these processes through the use of directed drugs opens up new promising avenues in combating AML. Thereby, a comprehensive elucidation of the significance of these AML BMM cells' metabolic and immune checkpoints and signaling pathways on leukemic cells can be undertaken in the future investigations. Additionally, these checkpoints and cells should be considered plausible multi-targeted therapies for AML in combination with other conventional treatments in AML. Video Abstract.

Abstract
Liquid biopsy technologies have the potential to transform cancer patient management as it offers non-invasive diagnosis and real-time monitoring of disease progression and treatment responses. The use of liquid biopsy for non-invasive cancer diagnosis can have pivotal importance for the African continent where access to medical infrastructures is limited, as it eliminates the need for surgical biopsies. To apply liquid biopsy technologies in the African setting, the influence of environmental and population genetic factors must be known. In this review, we discuss the use of circulating tumor cells, cell-free nucleic acids, extracellular vesicles, protein, and other biomolecules in liquid biopsy technology for cancer management with special focus on African studies. We discussed the prospect, barriers, and other aspects that pose challenges to the use of liquid biopsy in the African continent.

Abstract
Transmembrane serine proteases have been implicated in the development and progression of solid and hematological cancers. Human airway trypsin-like protease 4 (HAT-L4) is a transmembrane serine protease expressed in epithelial cells and exocrine glands. In the skin, HAT-L4 is important for normal epidermal barrier function. Here, we report an unexpected finding of ectopic HAT-L4 expression in neutrophils and monocytes from acute myeloid leukemia (AML) patients. Such expression was not detected in bone marrow cells from normal individuals or patients with chronic myeloid leukemia, acute lymphocytic leukemia and chronic lymphocytic leukemia. In AML patients who underwent chemotherapy, persistent HAT-L4 expression in bone marrow cells was associated with minimal residual disease and poor prognostic outcomes. In culture, silencing HAT-L4 expression in AML-derived THP-1 cells by short hairpin RNAs inhibited matrix metalloproteinase-2 activation and Matrigel invasion. In mouse xenograft models, inhibition of HAT-L4 expression reduced the proliferation and growth of THP-1 cell-derived tumors. Our results indicate that ectopic HAT-L4 expression is a pathological mechanism in AML and that HAT-L4 may be used as a cell surface marker for AML blast detection and targeting.

Abstract
Matrix metalloproteinases (MMPs) are responsible for the degradation of extracellular matrix components and hence play a crucial role in physiological and pathologic processes. The imbalance between the expression of MMPs and their inhibitors can be effective in leukemic cell processes such as migration, angiogenesis, survival, and apoptosis, playing a key role in the progression and prognosis of leukemia. In this review, we discuss the potential involvement of MMPs and their inhibitors in the pathogenesis and progression of leukemia by examining their role in the prognosis of leukemia. Inducing leukemic cell growth, migration, invasiveness, and angiogenesis are the main roles of MMPs in leukemia progression mediated by their degradative activity. Given the important role of MMPs in leukemia progression, further clinical trials are needed to confirm the link between MMPs' expressions and leukemia prognosis. It is hoped to use MMPs as therapeutic targets to improve patients' health by recognizing the prognostic value of MMPs in leukemia and their effect on the progression of these malignancies and their response to treatment.

Abstract
We investigated the biological functions and mechanism of miRNA‑301a on apoptosis in chronic myelogenous leukemia (CML). The expression of miRNA‑301a in patient with CML cells was higher than the expression of normal patients. Overall survival (OS) of chronic granulocytic leukemia cell patient with low miRNA‑301 expression was superior to that of CML patient with high miRNA‑301 expression. Moreover, the upregulation of miRNA‑301a increased cell proliferation, inhibited apoptosis and caspase-3 and -9 activity of K562 cells. Next, the upregulation of miRNA‑301a suppressed Bax/Bcl-2 rate and TIMP2 protein expression, increased phosphorylation-ERK1/2 and decreased phosphorylation-AKT protein expression of K562 cells. Furthermore, si‑TIMP2 expression enhanced the upregulation of miRNA‑301a on the promotion of cell proliferation, inhibition of apoptosis and caspase-3 and -9 activity, suppression of Bax/Bcl-2 rate, increasing phosphorylation-ERK1/2 and decreasing phosphorylation-AKT protein expression of K562 cells. Taken together, our results clearly suggested that miRNA‑301a induces apoptosis of CML cells by directly targeting the TIMP2/ERK1/2 and AKT pathways.

Abstract
Secreted matrix metalloproteinases (MMP)-2 and MMP-9 and membrane-anchored aminopeptidase-N/CD13 are abnormally expressed in human acute myeloid leukaemia (AML). We previously showed that CD13 ligation by anti-CD13 monoclonal antibodies can induce apoptosis in AML cells. Here, we assessed ADAM17 expression in primary blood blasts CD13+CD33+ from patients with AML. Primary AML cells expressed ADAM17 transcript and its surface expression was higher in subtype M4 (myelomonocytic) and M5 (monocytic) AML specimens than in M0 and M1/M2 (early and granulocytic) specimens. In AML cell lines defining distinct AML subfamilies (HL-60/M2, NB4/M3, THP-1/M5, U937/M5) and primary AML cells cultured ex vivo, anti-CD13 antibodies downregulated surface CD13 and ADAM17 without affecting MMP-2/-9 release. Knockdown of CD13 by siRNA prevented anti-CD13-mediated ADAM17 downregulation, indicating that CD13 is required for ADAM17 downregulation. Soluble ADAM17 was not detected in the medium of anti-CD13 treated cells, suggesting that ADAM17 was not shed. After ligation by anti-CD13, CD13 and ADAM17 were internalized. Subsequently, we found that ADAM17 interacts with CD13. We postulate that the interaction of ADAM17 with CD13 and its downregulation following CD13 engagement has important implications in AML for the known roles of ADAM17 in tumour-associated cell growth, migration and invasion.

Abstract
BACKGROUND Matrix metalloproteinase-2 (MMP-2) has been thought of as a predictor of recurrence or metastasis risk or prognostic markers in cancer. We evaluated whether preoperative serum levels of MMP-2 work as a prognostic biomarker in breast cancer prognosis. METHODS Preoperative serum levels of MMP-2 were measured with ELISA in 303 patients with histologically confirmed breast cancer. The median follow-up time for all patients was 4.24 years. The relationship of MMP-2 to survival was investigated using Cox proportional hazard regression model adjusted for the tumor-node-metastasis (TNM) stage and estrogen receptor (ER) status. RESULTS In the multivariate analysis, disease-free survival (DFS) was worse among patients with the third tertile of MMP-2 level than with the first tertile of MMP-2 level [hazard ratio, 1.80; 95% confidence interval (CI), 1.04-3.11; P = 0.04]. However, when the patients were stratified by age, ER status, histologic grade, and nuclear grade, inverse correlation was shown between serum MMP-2 levels and prognostic factors, and the associations between MMP-2 and DFS were only significant among patients with poor prognostic factors (HR, 2.75; 95% CI, 1.32-5.73 in ER-negative; HR, 2.90; 95% CI, 1.42-5.92 in histologic grade III; and HR, 2.61; 95% CI, 1.26-5.39 in nuclear grade III). CONCLUSIONS Our results suggest that the preoperative serum levels of MMP-2 were associated with the survival in patients with breast cancer in ER-negative, higher histologic grade, or higher nuclear grade breast cancers. IMPACT Our results indicate that serum levels of MMP-2 may play a role as prognostic biomarker in breast cancer survival.

Abstract
OBJECTIVES Angiogenesis seems important for both leukemogenesis and chemosensitivity in acute myelogenous leukemia (AML). Angiogenesis is regulated by the balance between pro- and antiangiogenic cytokines, which also indicates an important role of matrix metalloproteases (MMPs) and their natural inhibitors, tissue inhibitors of metalloproteases (TIMPs). We investigated the constitutive release of MMPs and TIMPs for a large group of consecutive AML patients. METHODS AML cells were cultured in vitro either alone or together with microvascular endothelial cells, and levels of MMPs and TIMPs were determined in culture supernatants. RESULTS AML cells showed constitutive release of several MMPs and TIMPs. For all patients, detectable MMP-10 release was observed, and most patients showed detectable release of at least one additional MMP, usually MMP-9 or MMP-2. A significant correlation was found between MMP-9 and TIMP-1 release and the release of several CCL and CXCL chemokines. MMP-9 release was higher for AML cells with monocytic differentiation corresponding to the FAB-subtype M4/M5 AML; it was mainly released in its inactive form, but endogenously active MMP-9 could be detected even in the presence of the constitutively released TIMP-1/2. Endothelial cells released relatively high levels of MMP-10, and these levels were further increased by coculture with AML cells. Patients achieving complete hematological remission after only one induction cycle showed relatively low constitutive MMP-2 release. CONCLUSION We conclude that primary human AML cells show constitutive release of both MMPs and TIMPs, and this release may be important for leukemogenesis and possibly also for chemosensitivity.

Abstract
This study evaluates the mRNA expression profile of genes TIMP1, TIMP2, MMP2 and MMP9 in diagnostic bone marrow samples from 134 consecutive ALL children by real-time quantitative PCR. A significant association was observed between higher expression levels of MMP9 and low risk group and absence of extramedullary infiltration and higher expression levels of TIMP2 and MMP2 with T-ALL. TIMP1 gene expression values higher than the median were associated with a significantly lower 5-year event free-survival in univariable (P=0.04) and multivariable analysis (P=0.01). Our data address new information in the complex interaction of the migration/adhesion genes and childhood ALL.

Abstract
The acquired drug resistance as well as extramedullary tissue infiltration of leukemic cells is a major obstacle in leukemia treatment. Excessive egress of leukemia cell blasts results in invasion into various organs or tissues, which is facilitated by the catalytic activities of matrix metalloproteinases (MMPs). However, the migration of chemoresistant leukemia cells remains unclear. Here, we generated drug-resistant variants of the human acute myeloid leukemia cell line (AML-2/WT) by stepwise exposure to anticancer drugs and evaluated the level of MMP-2 in the drug-resistant variants, along with their invasiveness. Each of the drug-resistant cell variants demonstrated predominant increases in the expression and gelatinolytic activity of MMP-2 as well as in invasiveness, which were significantly suppressed by both a MMP-2 inhibitor and a blocking antibody. Knockdown experiments using MMP-2 short hairpin RNA also indicated that its upregulation was strongly associated with the cells' increased invasive properties. Importantly, elevated levels of MMP-2 activity and invasiveness were observed in ex vivo mononuclear cell of bone marrow from patients with poor responses to chemotherapy. These findings suggest that advanced malignancy due to acquired drug resistance is responsible for the progressive invasiveness of leukemia cells via MMP-2.
