Described herein are methods of prolong or reactivating organogenesis in a subject in need thereof (e.g., a subject that has impaired organ function such as a prematurely born infant). The methods comprises increasing the expression or activity of Lin28A or Lin28B proteins, inhibiting the expression or activity of let-7 family microRNAs, and/or inhibiting the expression or activity of Dis3L2 exonuclease.

The present invention relates to the field of nephrology. More specifically, the present invention provides compositions and methods useful for the study and treatment of acute kidney injury. In one embodiment, the present invention provides a knockout animal whose genome comprises a deletion of exon 2 and exon 3 of kelch-like ECH-associated protein 1 (KEAP1) in T-cells. In another embodiment, a method for treating a subject diagnosed with AKI comprising the steps of (a) isolating T-cells from the subject; (b) activating Nrf2 expression in the isolated T-cells; and (c) administering the T-cells back to the subject.

Provided nucleic acid-based expression construct for the target cell-specific production of a therapeutic protein, such as a pro-apoptotic protein, within a target cell, including a target cell that is associated with aging, disease, or other condition, in particular a target cell that is a senescent cell or a cancer cell. Also provided are formulations and systems, including fusogenic lipid nanoparticle (LNP) formulations and systems, for the delivery of nucleic acid-based expression constructs as well as methods for making and using such nucleic acid-based expression constructs, formulations, and systems for reducing, preventing, and/or eliminating the growth and/or survival of a cell, such as a senescent cell and/or a cancer cell, which is associated with aging, disease, or other condition as well as methods for the treatment of aging, disease, or other conditions by the in vivo administration of a formulation, such as a fusogenic LPN formulation, comprising an expression construct for the target cell-specific production of a therapeutic protein, such as a pro-apoptotic protein, in a target cell that is associated with aging, disease, or other condition, in particular a target cell that is a senescent cell or a cancer cell.

A transgenic non-human animal model is disclosed. The system comprises an inducible transgene allowing the expression of a mutant POLG1 polypeptide that results in modulation of mitochondrial DNA copy number and/or concentration in the whole transgenic non-human animal or selected cells or tissues of the transgenic non-human animal. Methods of producing and using the model system are also provided.

The present invention relates to a non-human animal model of chronic glaucoma. In addition, the invention refers to a method for the preparation of said animal model, as well as to the use thereof.

This invention provides compositions of active highly phosphorylated lysosomal sulfatase enzymes, their pharmaceutical compositions, methods of producing and purifying such lysosomal sulfatase enzymes and compositions and their use in the diagnosis, prophylaxis, or treatment of diseases and conditions, including particularly lysosomal storage diseases that are caused by, or associated with, a deficiency in the lysosomal sulfatase enzyme.

The invention relates to improvement and therapy of neuronal conditions involving neurodegenerative, inflammatory and vascular conditions. More specifically, the invention provides compositions and methods for specific targeted elimination of apolipoprotein E4 (apoE4), and uses thereof in the treatment and prevention of ApoE4 associated conditions.

The present invention relates to photoreceptor precursor cells comprising a heterologous nucleic acid encoding an optogenetic inhibitor. The present invention also relates to a pharmaceutical composition comprising photoreceptor precursor cells of the invention and a pharmaceutically acceptable excipient. The present invention relates to photoreceptor precursor cells or pharmaceutical composition of the invention for use in the treatment of a retinal degenerative disease, preferably a retinal degenerative disease related to a loss of function or death of photoreceptors. Finally, the present invention relates to a method for producing the photoreceptor precursor cells of the invention, comprising i) providing photoreceptor precursor cells; and ii) introducing into said precursor cells a nucleic acid encoding optogenetic inhibitor.

The present disclosure provides methods and systems for performing, observing, and/or recording defecation motor program (DMP) events using microfluidic devices. The methods may be performed wherein the nematodes ingest fluorescent or color material and are then loaded in a microfluidic chip and stimulated to feed and defecate. DMP events are observed with use of a fluorescent microscope. In other methods, a microfluidic device with two or more electrodes is used to record electrical events of the DMP.

An object of the present invention is to provide a method for producing a non-human primate model of AMD, a method for evaluating the efficacy of a test substance in the prevention or treatment of AMD using the AMD animal model produced according to this method, and a method for screening substances effective in the prevention or treatment of AMD using the aforementioned AMD animal model. The method for preparing the AMD animal model consists of administering sodium iodate into a vitreous body of a non-human primate, and the method for evaluating the efficacy of a test substance in the prevention or treatment of AMD consists of preparing a non-human primate model of AMD according to the aforementioned method for preparing an AMD animal model, and evaluating the efficacy of the test substance in the prevention or treatment of AMD using the resulting AMD animal model.
