RESUMEN
INTRODUCTION: Brain metastasis is a highly traumatic event in the progression of malignant tumors, often symbolizing higher mortality. Metabolic alterations are hallmarks of cancer, and the mask of lipid metabolic program rearrangement in cancer progression is gradually being unraveled. AREAS COVERED: In this work, we reviewed clinical and fundamental studies related to lipid expression and activity changes in brain metastases originating from lung, breast, and cutaneous melanomas, respectively. Novel roles of lipid metabolic reprogramming in the development of brain metastasis from malignant tumors were identified and its potential as a therapeutic target was evaluated. Published literature and clinical studies in databases consisting of PubMed, Embase, Scopus and www.ClinicalTrials.gov from 1990 to 2022 were searched. EXPERT OPINION: Lipid metabolic reprogramming in brain metastasis is involved in de novo lipid synthesis within low lipid availability environments, regulation of lipid uptake and storage, metabolic interactions between brain tumors and the brain microenvironment, and membrane lipid remodeling, in addition to being a second messenger for signal transduction. Although some lipid metabolism modulators work efficiently in preclinical models, there is still a long way to go from laboratory to clinic. This area of research holds assurance for the organ-targeted treatment of brain metastases through drug-regulated metabolic targets and dietary interventions.
RESUMEN
Blood has an important role in the healthcare system, particularly in blood transfusions and immunotherapy. However, the occurrence of outbreaks of infectious diseases worldwide and seasonal fluctuations, blood shortages are becoming a major challenge. Moreover, the narrow specificity of immune cells hinders the widespread application of immune cell therapy. To address this issue, researchers are actively developing strategies for differentiating induced pluripotent stem cells (iPSCs) into blood cells in vitro. The establishment of iPSCs from terminally differentiated cells such as fibroblasts and blood cells is a straightforward process. However, there is need for further refinement of the protocols for differentiating iPSCs into immune cells and red blood cells to ensure their clinical applicability. This review aims to provide a comprehensive overview of the strategies and challenges facing the generation of iPSC-derived immune cells and red blood cells.
RESUMEN
OBJECTIVE: To explore the hematological and clinical features of patients with malignant lymphoma (ML) combined with venous thromboembolism (VTE). METHODS: Sixty patients with ML combined with VTE in our hospital from May 2014 to May 2016 were enrolled in ML+VTE group, out of them 42 patients were males and 18 patients with females; another 60 patients with ML alone were enrolled in control group, out of them 43 patients were males and 17 patients females. The hematological, coagulation and clinical datas of all the patients were collected and then retrospectively analyzed. RESULTS: About 81.54% of the patients in ML+VTE group were found in Stage â ¢B-â £ tumor, and about 66.67% patients were found after ML was diagnosed; about 85.00% were with deep vein thrombosis (DVT), 10.00% were with pulmonary embolism (PE), and 5.00% were complicated with both DVT and PE. Common DVT locations in 56.67% cases were the upper limb and the neck vein(56.67%); The total effective rate of the cases with DVT was 49.02%, and the rate of cases with PE was 14.29%, and 0 in the cases with both DVT and PE, the difference was statistically significant (χ2=72.650, P<0.001). Compared with the patients of control group, the levels of platelet aggregation, D-dimer, high cut blood viscosity, low cut blood viscosity, plasma viscosity, hematocrit, assembly index of erythrocyte, and rigidity index of erythrocyte were higher in patients of ML+VTE group (P<0.05), and APTT, erythrocy tesed imentation rate, deformability index of erythrocyte, and average velocity of blood flow were reduced, the differences were statistically significant (P<0.05). CONCLUSION: Hemaorheology and coagulation of patients with ML combined with VTE indicate changes in the sensitivity state of thromboembolism; DVT, which is commonly manifested in the upper limb and the neck vein, and it mainly observed in patients with end-stage.
