Targeting Catechol-O-Methyltransferase Induces Mitochondrial Dysfunction and Enhances the Efficacy of Radiotherapy in Glioma.

Radiotherapy (RT) is commonly used to try to eliminate any remaining tumor cells following surgical resection of glioma. However, tumor recurrence is prevalent, highlighting the unmet medical need to develop therapeutic strategies to enhance the efficacy of RT in glioma. Focusing on the radiosensitizing potential of the currently approved drugs known to cross the blood-brain barrier can facilitate rapid clinical translation.

Mobilization strategies with and without plerixafor for autologous stem cell transplant in patients with multiple myeloma.

Autologous stem cell transplantation is a standard treatment strategy for patients with multiple myeloma that requires effective mobilization and apheresis of peripheral blood progenitor cells; however, in the current era of novel myeloma induction therapies, the optimal mobilization regimen to enhance stem cell yield while limiting toxicity and resource utilization remains unknown. In this multicenter retrospective study, we assessed apheresis and transplant outcomes in myeloma patients mobilized with granulocyte colony stimulating factor (G-CSF) alone (n = 62), G-CSF with chemotherapy (n = 43), or G-CSF with the CXCR4 antagonist plerixafor (n = 417). Compared to patients treated with G-CSF alone, the plerixafor group required significantly fewer median apheresis sessions (1 vs 2, p = 0.

In this study, we propose a novel therapeutic strategy for treating AML by inhibiting SIRT3 to regulate mitochondrial metabolism network involved in energy metabolism and epigenetic modifications essential for AML survival. A series of thieno [3,2-d]pyrimidine-6-carboxamide derivatives were designed and synthesized by structure-based strategy, 17f was documented to be a potent and acceptable selective SIRT3 inhibitor with IC value of 0.

Targeted Antioxidant Therapy Reduces Hyperglycemic Exacerbation of Myocardial Ischemia/Reperfusion Injury.

Introduction: Acute hyperglycemia (HG) enhances inflammatory and oxidative stress and exacerbates myocardial infarct size during ischemia-reperfusion injury by activating splenic leukocytes. Formyl peptide receptor 1 (FPR1) on leukocytes is activated by and mediates myocardial ischemia-reperfusion injury. We hypothesize that selective FPR1 antagonist cinnamoyl-F-(D)L-F-(D)L-F (CF) or potent reducing agent tris (2-carboxyethyl) phosphine hydrochloride (TCEP) could abrogate hyperglycemic infarct exacerbation, both alone and synergistically via a novel CF-TCEP compound that would target leukocytes for antioxidative effect.

Regulatory T and CXCR3+ Circulating Tfh Cells Concordantly Shape the Neutralizing Antibody Responses in Individuals Who Have Recovered from Mild COVID-19.

Regulatory T (Treg) cells are involved in the antiviral immune response in patients with coronavirus disease 2019 (COVID-19); however, whether Treg cells are involved in the neutralizing antibody (nAb) response remains unclear. Here, we found that individuals who recovered from mild but not severe COVID-19 had significantly greater frequencies of Treg cells and lower frequencies of CXCR3+ circulating T follicular helper (cTfh) cells than healthy controls. Furthermore, the frequencies of Treg and CXCR3+ cTfh cells were negatively and positively correlated with the nAb responses, respectively, and Treg cells was inversely associated with CXCR3+ cTfh cells in individuals who recovered from mild COVID-19 but not in those with severe disease.

VHL loss enhances antitumor immunity by activating the anti-viral DNA-sensing pathway.

von Hippel-Lindau (), known as a tumor suppressor gene, is frequently mutated in clear cell renal cell carcinoma (ccRCC). However, mutation is not sufficient to promote tumor formation. In most cases other than ccRCC, loss alters cellular homeostasis and causes cell stress and metabolic changes by stabilizing hypoxia-inducible factor (HIF) levels, resulting in a fitness disadvantage.
