Abstract Objectives: KH-type splicing regulatory protein (KHSRP) is an RNA-binding protein involved in several cellular processes, including nuclear splicing, mRNA localization, and cytoplasmic degradation. While KHSRP’s role has been studied in other cancers, its specific involvement in gastric cancer remains poorly understood. This study aims to explore KHSRP expression in gastric cancer and its potential effects on tumor progression and immune response. Methods: KHSRP expression in gastric cancer tissues and normal tissues was analyzed using data from The Cancer Genome Atlas (TCGA) database. The correlation between KHSRP expression, patient survival, and immune response was also assessed.… More >

Abstract Background: Clear cell renal carcinoma (ccRCC), the leading histological subtype of RCC, lacks any targeted therapy options. Although some studies have shown that early growth response factor 1 (EGR1) has a significant role in cancer development and progression, its role and underlying mechanisms in ccRCC remain poorly understood. Methods: The Cancer Genome Atlas (TCGA) database was utilized to examine the expression of EGR1 in ccRCC. The expression of EGR1 in 55 ccRCC tissues was evaluated using immunohistochemistry. The link between EGR1 expression and clinicopathological variables was examined through an analysis. Gain-of-function assays were employed to… More >

Abstract Angiogenesis, the expansion of pre-existing vascular networks, is crucial for normal organ growth and tissue repair, but is also involved in various pathologies, including inflammation, ischemia, diabetes, and cancer. In solid tumors, angiogenesis supports growth, nutrient delivery, waste removal, and metastasis. Tumors can induce angiogenesis through proangiogenic factors including VEGF, FGF-2, PDGF, angiopoietins, HGF, TNF, IL-6, SCF, tryptase, and chymase. This balance is disrupted in tumors, and extracellular vesicles (EVs) contribute to this by transferring proangiogenic factors and increasing their expression in endothelial cells (ECs). Malignant melanoma, a particular type of skin cancer, accounts for More >

Abstract Background: Rho GTPases are essential regulators for cellular movement and intracellular membrane trafficking. Their enzymatic activities fluctuate between active GTP-bound and inactive GDP-bound states regulated by GTPase activating proteins (GAPs) and guanine nucleotide exchange factors (GEFs). Arhgap39/Vilse/Porf-2 is a newly identified GAP. The role of Arhgap39 in migration and invasion has not been addressed thoroughly. Methods: The Arhgap39 gene was knocked out by Crispr-Cas9 gene editing in mouse Hepa1-6 and Hepa-1c1c7 cells to analyze the impact of Arhgap39 depletion on migration and invasion. Results: Loss of Arhgap39 noticeably increased the migration and invasive potential. Purified Arhgap39… More >

Abstract The B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1) protein of the polycomb complex is an essential mediator of the epigenetic transcriptional silencing by the chromatin structure. It has been reported to be crucial for homeostasis of the stem cells and tumorigenesis. Though years of investigation have clarified Bmi-1’s transcriptional regulation, post-translational modifications, and functions in controlling cellular bioenergetics, pathologies, and DNA damage response, the full potential of this protein with so many diverse roles are still unfulfilled. Bmi-1 is overexpressed in many human malignancies. Unraveling the Bmi-1’s precise functional role in head and neck… More >

Abstract Background: Hepatocellular carcinoma (HCC) is a health problem due to multi-drug resistance (MDR). Codelivery of multiple oncotherapy in one cargo as chimeric cancer therapy (CCT) is suggested as a solution for MDR. This study aims to engineer chitosan-coated nanostructure lipid carriers (NLCs) loaded with gefitinib (GF) and simvastatin (SV) as CCT for HCC. Methods: Both GF and SV-loaded nanostructure lipids carriers (GFSVNLC) and chitosan-capped GF and SV-loaded nanostructure lipids carriers (CGFSVNLC) formulations were assembled by top-down techniques. Moreover, particle size (PS), zeta potential (ZP), and polydispersity index (PDI) were measured by Zetasizer. The biosafety of… More > Graphic Abstract

Abstract Cancer, a leading cause of global mortality, remains a significant challenge to increasing life expectancy worldwide. Forkhead Box R2 (FOXR2), identified as an oncogene within the FOX gene family, plays a crucial role in developing various endoderm-derived organs. Recent studies have elucidated FOXR2-related pathways and their involvement in both tumor and non-tumor diseases. Dysregulation of FOXR2 has been linked to numerous malignant tumors, spanning the brain, nervous system, thyroid, osteosarcoma, Hodgkin lymphoma, colorectal, liver, pancreatic, lung, breast, ovarian, prostate, female genital tract, endometrial, and uterine cancers. Despite extensive research on FOXR2 dysregulation, its practical applications More >

Abstract Objectives: Mitochondrial Ca²⁺ uniporter (MCU) provides a Ca²⁺ influx pathway from the cytosol into the mitochondrial matrix and a moderate mitochondrial Ca²⁺ rise stimulates ATP production and cell growth. MCU is highly expressed in various cancer cells including breast cancer cells, thereby increasing the capacity of mitochondrial Ca²⁺ uptake, ATP production, and cancer cell proliferation. The objective of this study was to examine MCU inhibition as an anti-cancer mechanism. Methods: The effects of MCU-i4, a newly developed MCU inhibitor, on cell viability, apoptosis, cytosolic Ca²⁺, mitochondrial Ca²⁺ and potential, glycolytic rate, generation of ATP, and reactive oxygen species,… More >

Abstract Objectives: Melanoma is a highly aggressive and metastatic form of cancer, and the role of exosomal microRNAs (miRNAs) in its progression remains largely unexplored. This study aimed to investigate the effects of melanoma cell-derived exosomal miR-424-5p on angiogenesis and its underlying mechanisms. Methods: Exosomes were isolated from melanoma cell lines A375 and A2058, and their effects on the proliferation, migration, and angiogenesis of human umbilical vein endothelial cells (HUVECs) were examined. The interaction between miR-424-5p and its target gene, large tumor suppressor kinase 2 (LATS2), was analyzed using luciferase reporter assays and functional experiments. In vivo,… More >
