Inspired by calcium-induced reversible assembly and disassembly of membrane proteins found in nature, here we developed a phosphorylated amphiphile (PA) that contains an oligo(phenylene-ethynylene) unit as a hydrophobic unit and a phosphate ester group as a hydrophilic calcium-binding unit. We demonstrated that PA can assemble and disassemble in a reversible manner in response to the sequential addition of calcium chloride and ethylene-diaminetetraacetic acid within the lipid bilayer membranes for the first time as a synthetic molecule.

Targeting Mitochondrial Cholesterol Efflux via TCF21/ABCA10 Pathway to Enhance Cisplatin Efficacy in Ovarian Cancer.

Biochem Genet

October 2024

The Fourth Department of Gynecology and Oncology, The Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University/Hunan Cancer Hospital, Changsha, 410013, Hunan, People's Republic of China.

Article Synopsis
  • Cisplatin resistance is a major issue in ovarian cancer treatment, with mitochondrial cholesterol levels linked to chemoresistance; this study focuses on the TCF21/ABCA10 axis influencing this resistance.
  • ABCA10, a cholesterol transport protein, is found to be highly expressed in normal ovarian tissues but significantly downregulated in ovarian cancer tissues and DDP-resistant cell lines.
  • Various experimental techniques, including cell proliferation assays and luciferase reporter assays, were employed to confirm the interaction between TCF21 and ABCA10, along with observing the effects on cholesterol metabolism and cell function in ovarian cancer cells.

Hypothermia Inhibits Dexmedetomidine-Induced Contractions in Isolated Rat Aortae.

Int J Mol Sci

March 2024

Institute of Medical Science, Gyeongsang National University, Jinju-si 52727, Gyeongsangnam-do, Republic of Korea.

Dexmedetomidine is widely used to induce sedation in the perioperative period. This study examined the effect of hypothermia (33 and 25 °C) on dexmedetomidine-induced contraction in an endothelium-intact aorta with or without the nitric oxide synthase inhibitor N-nitro-L-arginine methyl ester (L-NAME). In addition, the effect of hypothermia on the contraction induced by dexmedetomidine in an endothelium-denuded aorta with or without a calcium-free Krebs solution was examined.

The mitochondrial permeability transition pore (MPTP) is a calcium-dependent, ion non-selective membrane pore with a wide range of functions. Although the MPTP has been studied for more than 50 years, its molecular structure remains unclear. Short-term (reversible) opening of the MPTP protects cells from oxidative damage and enables the efflux of Ca ions from the mitochondrial matrix and cell signaling.

Background: Pathological cardiac hypertrophy is one of the main activators of heart failure. Currently, no drug can completely reverse or inhibit the development of pathological cardiac hypertrophy. To this end, we proposed a silicate ion therapy based on extract derived from calcium silicate (CS) bioceramics for the treatment of angiotensin II (Ang II) induced cardiac hypertrophy.
