NOVEL APPROACH FOR INCREASING CONTRACTILITY IN PATIENTS WITH SYSTOLIC HEART FAILURE

The method for increasing contractility in patients with systolic heart failure involves screening for candidate small molecules which block the interaction between Rad and the plasma membrane and/or block the interaction between Rad and the Ca.sub.V1.2/Ca.sub.Vβ2 complex, or between Rad and Ca.sub.Vβ2, in order to increase cardiac contractility. A method for preventing calcium overload and arrhythmias in heart disease involves preventing the dissociation of Rad and the Ca.sub.V1.2/Ca.sub.Vβ2 complex, or between Rad and Ca.sub.Vβ2, during beta-adrenergic system activation. Additionally, a method of screening for drugs that block interaction between an RGK GTPase protein and a β-subunit of the calcium channel is provided. A suitable technique, such as fluorescence resonance energy transfer (FRET), may be used to assess blocking of the interaction between the RGK GTPase protein and the β-subunit of the calcium channel for the treatment of heart disease, pain, diabetes, skeletal muscle disorders and/or central nervous system (CNS) disorders.

ENGINEERING SPATIAL-ORGANIZED CARDIAC ORGANOIDS FOR DEVELOPMENTAL TOXICITY TESTING
20220397564 · 2022-12-15 · ·

A developmental toxicity screening assay using spatially organized cardiac organoids with contracting cardiomyocytes in the center surrounded by stromal cells distributed along the pattern perimeter engineered from human induced pluripotent stem cells (hiPSCs). Cardiac organoids generated from 600 μm-diameter circles were used as a developmental toxicity screening assay for the quantification of the embryotoxic potential of nine pharmaceutical compounds. The cardiac organoids were demonstrated as having a potential use as an in vitro platform for studying organoid structure-function relationships, developmental processes, and drug-induced cardiac developmental toxicity.

In the culturing method, primary cells are cultured on a culture vessel coated with an extracellular matrix gel by using the culture medium, and the primary cells grow on the culture vessel, which has been coated with the extracellular matrix gel, and proliferate rapidly under the combined action of nutrient factors and an extracellular matrix contained in the primary cell culture medium. The cell model obtained by the primary cell culture medium and the primary cell culture method can be used for the evaluating the efficacy of and screening drugs.

METHOD FOR SCREENING SECRETION-PRODUCING CELLS AND KIT FOR SCREENING SECRETION-PRODUCING CELLS
20220381768 · 2022-12-01 · ·

A method for screening secretion-producing cells is provided, in which a cell that produces a secretion of interest is subjected to screening from a plurality of cells. The method includes capturing the cell and at least one detection particle that is allowed to capture the secretion of interest in each of a plurality of wells having a bottom section with a through-hole sized such that the cell does not pass through, causing the cell captured in each of the plurality of wells to produce a secretion, detecting the secretion of interest captured by the at least one detection particle, and identifying, based on a result of the detection as an index, a well in which a cell producing the secretion of interest is captured from the plurality of wells. Each of the wells has a size allowing the cell to be captured in one cell unit in a state in which one or more detection particles are captured.

Use of erythropoietin-derived peptide through effect on cell damage prevention thereof

A peptide is described herein that has: (i) a simple structure compared to existing natural human erythropoietin, thus capable of easily passing through a tissue-blood barrier, (ii) excellent bioactivity with respect to cell-protecting activity, (iii) a low manufacturing cost, thus being economically advantageous, and (iv) no side effects on cell proliferation. Also, a pharmaceutical composition comprising the erythropoietin-derived peptide described herein as an active ingredient is described. The pharmaceutical composition may be used for preventing or treating cell damage-related illnesses, such as stroke, mechanical damage or ischemic damage to the nervous system, myocardial infarction, retinal damage, and diabetes. Also, the described pharmaceutical composition may be used for preventing cell damage.
