In vitro repositioning therapy with olaparib, temozolomide and oxaliplatin in glioblastoma cell lines: U118, U87, U251, H4 and human fibroblasts.

Background: Central nervous system (CNS) tumors, including gliomas, are among the most aggressive cancers, with glioblastoma multiforme (GBM) being the most common and lethal. This study explores the potential of multidrug repositioning as a modern chemotherapy strategy for GBM cell lines. It combines the standard GBM chemotherapeutic temozolomide (TMZ) with olaparib (OLA) and oxaliplatin (OXA), both repurposed from other cancer types.

Non-cancer effects after proton beam therapy for pediatric tumors- a narrative review.

Introduction: Radiation therapy can cause serious complications and side effects, especially in children. Proton beam therapy is considered as safer and more effective than traditional photon therapy because this type of modality offers precise radiation dose delivery to cancer cells while minimizing irradiation dose to adjacent normal tissue. Moreover, pediatric patients undergoing PBT may also experience a range of non-cancer late effects, including brainstem injury, cognitive dysfunctions, and side effects from endocrine or cardiovascular systems.

Therapeutic role of eicosapentaenoic and arachidonic acid in benzo(a) pyrene-induced toxicity in HUVEC endothelial cells.

Endothelial cells are characterized by intense metabolic activity and control of homeostasis. Exposure to benzo(a)pyrene (BaP) plays an important role in the etiology of atherosclerosis. The study aimed to determine the effect of arachidonic (ARA), and eicosapentaenoic acid (EPA) on pro-inflammatory gene and protein levels in human umbilical vein endothelial cells (HUVEC) exposed to BaP.

Effect of Eicosapentaenoic Acid Supplementation on Murine Preadipocytes 3T3-L1 Cells Activated with Lipopolysaccharide and/or Tumor Necrosis Factor-α.

The beneficial effect of n-3 fatty acids can be related to anti-inflammatory properties. The aim of the study was to analyzed the effect of eicosapentaenoic acid (EPA) on 3T3-L1 cells (murine embryonic fibroblasts‒preadipocytes) activated with inflammatory factors (IF). Cells were incubated with 50 µmol of EPA for 48 h, and then activated with lipopolysaccharide (LPS) or tumor necrosis factor-α (TNF-α).
