The present invention is related to short-term renal injury models and methods for creating these models. The models and methods can be used for identifying, testing or characterizing candidate molecules with respect to their suitability to treat renal injury. The methods comprise a step of inducing, in a test subject, renal injury by administering subcutaneously a bolus of a renal injury inducer, in a dosage sufficiently high to induce renal injury. Different types of readout for renal injury are provided such as albumin creatinine ratio (ACR) determined in a urine sample taken from the subject, or the development of transcutaneous fluorescence after injection of a fluorescent molecule. Based on the readout the degree of renal injury and/or alteration of GFR can be determined.

Compositions comprising nanoparticles, nanoplexes or virus comprising isolated nucleic acid comprising nucleic acid encoding a mammalian, and methods of using the compositions, are provided.

This document relates to non-human animal models (e.g., non-human mammalian models such as mouse models) for aging (e.g., neural aging). For example, non-human animal models having reduced or eliminated levels of aralkylamine N-acetyltransferase (AANAT) polypeptide expression are provided.

This invention relates to the finding that testis development related protein (TDRP; also termed Immunomoodulin or Imood herein) is a circulatory anxiogenic factor that modulates anxiety-like behaviour in mammalian models through the regulation of the immune system. Methods of treatment of mental disorders, such as anxiety, and TDRP antagonists for use in such methods are provided. Methods of diagnosing or monitoring a mental disorder in an individual by determining levels of TDRP in a sample and methods of screening for compounds that reduce levels of TDRP are provided.

Disclosed herein are methods for modulating hair growth and increasing hair follicle stem cell activation in an individual in need thereof. This includes administering an agent that modulates a Gas6-Tyro3-Axl-Mertk (TAM) interaction or pathway.

Described herein are methods of prolonging 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 comprise 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 purpose of the present invention is to provide a novel medical application of pluripotent stem cells (muse cells) in regeneration medicine. The present invention provides a cell preparation and a pharmaceutical composition which are for amelioration and treatment of brain disorders resulting from fetal growth retardation, such as abnormal motor quality or abnormal neurological development, and which contain SSEA-3 positive pluripotent stem cells isolated from a mesenchymal tissue from a live body or cultured mesenchymal cells. It is assumed that this cell preparation is based on a mechanism where muse cells that are administered to objects having the disorders are engrafted on an impaired brain tissue, thereby ameliorating or treating the disorders.

Disclosed are nucleic acid constructs comprising a nucleic acid sequence encoding a vitelliform macular dystrophy-2 (VMD2) promoter operably linked to a nucleic acid sequence encoding Rap1a. Disclosed are vectors comprising the nucleic acid constructs disclosed herein. Disclosed are compositions comprising the disclosed nucleic acid constructs or vectors. Also disclosed are methods of treating a subject having age-related macular degeneration comprising administering one or more of the disclosed nucleic acid constructs, vectors, or compositions to a subject in need thereof.

Disclosed are Pear 1 and, serving as a target of fibrotic diseases, applications in a medicament for treating human Pear 1-related diseases. Also disclosed are a Pear 1-targeting antibody or a mutant of same or a composition comprising same and applications thereof. Disclosed are a humanized Pear 1 transgenic mice model, a construction method for same, and applications thereof. The technical solution of the present invention regulates fibroblast activation and has broad application prospects in treating fibrotic diseases and accompanying debilitating diseases.

A method of integrating a biological tissue with a vascular system in vitro, comprising coculturing a biological tissue with vascular cells and mesenchymal cells. A biological tissue which has been integrated with a vascular system by the above-described method. A method of preparing a tissue or an organ, comprising transplanting the biological tissue described above into a non-human animal and differentiating the biological tissue into a tissue or an organ in which vascular networks have been constructed.
