Article Abstract
TOR (target of rapamycin), an evolutionarily-conserved serine/threonine kinase, acts as a central regulator of cell growth, proliferation and survival in response to nutritional status, growth factor, and stress signals. It plays a crucial role in coordinating the balance between cell growth and cell death, depending on cellular conditions and needs. As such, TOR has been identified as a key modulator of autophagy for more than a decade, and several deregulations of this pathway have been implicated in a variety of pathological disorders, including cancer. At the molecular level, autophagy regulates several survival or death signaling pathways that may decide the fate of cancer cells; however, the relationship between autophagy pathways and cancer are still nascent. In this review, we discuss the recent cellular signaling pathways regulated by TOR, their interconnections to autophagy, and the clinical implications of TOR inhibitors in cancer.

Background: Breast cancer treatment, particularly during the perioperative period, is often accompanied by significant psychological distress, including anxiety and uncertainty. Mobile health (mHealth) interventions have emerged as promising tools to provide timely psychosocial support through convenient, flexible, and personalized platforms. While research has explored the use of mHealth in breast cancer prevention, care management, and survivorship, few studies have examined patients' experiences with mobile interventions during the perioperative phase of breast cancer treatment.

Superoxide dismutases (SODs) are key regulators of reactive oxygen species (ROS) and redox balance. Although intracellular SODs have been extensively studied, growing attention has been directed toward understanding the roles of extracellular SODs in both Dictyostelium and mammalian systems. In Dictyostelium discoideum, SodC is a glycosylphosphatidylinositol (GPI)-anchored enzyme that modulates extracellular superoxide to regulate Ras, PI3K signaling, and cytoskeletal remodeling during directional cell migration.

Colorectal cancer ranks among the most prevalent and lethal malignant tumors globally. Historically, the incidence of colorectal cancer in China has been lower than that in developed European and American countries; however, recent trends indicate a rising incidence due to changes in dietary patterns and lifestyle. Lipids serve critical roles in human physiology, such as energy provision, cell membrane formation, signaling molecule function, and hormone synthesis.

Background And Aims: Liver metastasis significantly contributes to poor survival in patients with colorectal cancer (CRC), posing therapeutic challenges due to limited understanding of its mechanisms. We aimed to identify a potential target critical for CRC liver metastasis.
Methods: We analyzed the Gene Expression Omnibus (GEO) and the Cancer Genome Atlas (TCGA) databases and identified EphrinA3 (EFNA3) as a potential clinically relevant target.

Acute Myeloid Leukemia (AML) patient-derived Mesenchymal Stem Cells (MSCs) behave differently than normal ones, creating a more protective environment for leukemia cells, making relapse harder to prevent. This study aimed to identify prognostic biomarkers and elucidate relevant biological pathways in AML by leveraging microarray data and advanced bioinformatics techniques. We retrieved the GSE122917 dataset from the NCBI Gene Expression Omnibus and performed differential expression analysis (DEA) within R Studio to identify differentially expressed genes (DEGs) among healthy donors, newly diagnosed AML patients, and relapsed AML patients.
