AI Article Synopsis

  • Chemotherapy remains the primary treatment for many cancers, but its effectiveness is limited by drug resistance often linked to lysosomal functions in cells.
  • Lysosomes play a dual role by sequestering chemotherapeutic drugs, thus lowering their availability and enhancing resistance; they also contribute to cancer progression through enzymatic activity and triggering cell death.
  • The review discusses mechanisms of lysosomal drug sequestration and explores strategies to target lysosomes, aiming to reverse drug resistance and improve cancer treatment outcomes.

Article Abstract

Chemotherapy is still the major method of treatment for many types of cancer. Curative cancer therapy is hampered significantly by medication resistance. Acidic organelles like lysosomes serve as protagonists in cellular digestion. Lysosomes, however, are gaining popularity due to their speeding involvement in cancer progression and resistance. For instance, weak chemotherapeutic drugs of basic nature permeate through the lysosomal membrane and are retained in lysosomes in their cationic state, while extracellular release of lysosomal enzymes induces cancer, cytosolic escape of lysosomal hydrolases causes apoptosis, and so on. Drug availability at the sites of action is decreased due to lysosomal drug sequestration, which also enhances cancer resistance. This review looks at lysosomal drug sequestration mechanisms and how they affect cancer treatment resistance. Using lysosomes as subcellular targets to combat drug resistance and reverse drug sequestration is another method for overcoming drug resistance that is covered in this article. The present review has identified lysosomal drug sequestration as one of the reasons behind chemoresistance. The article delves deeper into specific aspects of lysosomal sequestration, providing nuanced insights, critical evaluations, or novel interpretations of different approaches that target lysosomes to defect cancer.

Background Context: On radiopathological examination of spinal tuberculosis (TB), two predominant forms are known: dry and wet types. Wet TB, as the name suggests, has abscess formation as its predominant presenting feature and is the exudative form; dry TB includes caseation and sequestration with minimal exudate. Dry TB often exhibits poorer recovery patterns than the wet counterparts, which can be possibly ascribed to vasculitis, ischemia, or tubercular myelitis, rather than isolated mechanical compression.

Acute pancreatitis (AP) is a highly fatal pancreatic inflammation. In recent years, synthetic nanoparticles have been extensively developed as drug carriers to address the challenges of systemic adverse reactions and lack of specificity in drug delivery. However, systemically administered nanoparticle therapy is rapidly cleared from circulation by the mononuclear phagocyte system (MPS), leading to suboptimal drug concentrations in inflamed tissues and suboptimal pharmacokinetics.

Insights into the Mechanism of Protein Loading by Chain-Length Asymmetric Complex Coacervates.

Biomacromolecules

The study of the phase behavior of polyelectrolyte complex coacervates has attracted significant attention in recent years due to their potential use as membrane-less organelles, microreactors, and drug delivery platforms. In this work, we investigate the mechanism of protein loading in chain-length asymmetric complex coacervates composed of a polyelectrolyte and an oppositely charged multivalent ion. Unlike the symmetric case (polycation + polyanion), we show that protein loading is highly selective based on the protein's net charge: only proteins with charges opposite to the polyelectrolyte can be loaded.

Mitochondrial activity is necessary for the maintenance of many liver functions. In particular, mitochondrial fatty acid oxidation (FAO) is required for energy production and lipid homeostasis. This key metabolic pathway is finely tuned by the mitochondrial respiratory chain (MRC) activity and different transcription factors such as peroxisome proliferator-activated receptor α (PPARα).

Theoretical Study of Antioxidant and Prooxidant Potency of Protocatechuic Aldehyde.

Int J Mol Sci

January 2025

Institute for Information Technologies Kragujevac, Department of Science, University of Kragujevac, Jovana Cvijića bb, 34000 Kragujevac, Serbia.

In this study, the antioxidant and prooxidant potency of protocatechuic aldehyde (PCA) was evaluated using density functional theory (DFT). The potency of direct scavenging of hydroperoxyl (HOO) and lipid peroxyl radicals (modeled by vinyl peroxyl, HC=CHOO) involved in lipid peroxidation was estimated. The repair of oxidative damage in biomolecules (lipids, proteins and nucleic acids) and the prooxidant ability of PCA phenoxyl radicals were considered.
