The disclosure provides for methods and compositions for treating a premature aging disorder or neurodegenerative disorder, particularly neurodegenerative disorders associated with amyloid deposition and neuronal death, such as Alzheimer's disease. Accordingly, aspects of the disclosure relate to a method for treating a premature aging disorder in a subject in need thereof, comprising administering a TERT activating therapy to the subject. Further aspects relate to a method for treating a neurodegenerative disorder in a subject comprising administering a TERT activating therapy to the subject.

The present disclosure provides genome engineering proteins, e.g., nucleic acid binding domains and/or functional domains that have a net positive charge and are cell permeable and can be introduced into the cells without the use of a carrier such as micelles, vesicles, liposomes, and the like.

An application of a UTX gene in preparation of drugs for preventing or treating lipid diseases. The invention further discloses a method for knocking out a UTX gene from a mouse liver. The invention further discloses a UTX overexpression adenovirus as well as a preparation method and an application thereof. The invention further discloses a method for upregulating UTX expression in a mouse liver. The invention further discloses therapeutic action of UTX overexpression on HFD induced hyperlipidemia and NAFLD. The invention provides an available laboratory basis for preparing lipid-lowering drugs, so that the UTX can be used for preparing drugs affecting the lipid, and a new research method is provided for researching the occurrence and development of dyslipidemia.

A protein antigen combination for detecting Alzheimer's disease autoantibodies in human serum sample and an application thereof are disclosed. The protein antigen combination includes at least two protein fragments selected from the following proteins: MAPT, ADARB1, P21, DNAJC8, RAGE, ASXL1, and JMJD2D. Based on the protein antigen composition, a kit for diagnosis, especially for early diagnosis of Alzheimer's disease or its related risks, can be prepared. By using the protein antigen composition provided by the invention, early Alzheimer's disease can be quickly and accurately diagnosed, which has important practical significance.

The present disclosure relates generally to compositions and methods for treating cancer and neoplastic disease. Provided herein are substituted pyridine derivative compounds, and compositions (including pharmaceutical compositions) that include these compounds. The subject compounds and compositions are useful for inhibition of at least one histone demethylase. Furthermore, the subject compounds and compositions are useful for the treatment of cancer or neoplastic disease, such as prostate cancer, breast cancer, bladder cancer, lung cancer, melanoma, retinoblastoma, or multiple endocrine neoplasia type 1.

Disclosed herein are methods and compositions for identifying transcriptional and epigenetic age-related markers. Disclosed herein are also methods and compositions for reprogramming cell age by modulating transcriptional and epigenetic age-related markers identified herein. The identified transcriptional and epigenetic age-related markers can also be used for measuring cellular age in a cell or tissue.

The present disclosure provides genome engineering proteins, e.g., nucleic acid binding domains and/or functional domains that have a net positive charge and are cell permeable and can be introduced into the cells without the use of a carrier such as micelles, vesicles, liposomes, and the like.

A method for identifying a compound that inhibits an activity of a histone lysine demethylase, in which the compound interacts with three sites of a pocket of the histone lysine demethylase generated by using a computer program, an alpha-ketoglutarate (AKG), a methylated lysine, and a NIQ.

The present invention features compositions and methods for recapitulating physiological X-chromosome inactivation (XCI) in a cell, including a cell of any embryo generated by Somatic Cell Nuclear Transfer (SCNT). In one aspect, the invention features a method for generating physiological X chromosome inactivation in an embryo generated by SCNT, the method comprising injecting the embryo generated via SCNT with an H3K27me3-specific demethylase polypeptide or a polynucleotide encoding said demethylase. Disclosed herein are methods, compositions, and kits comprising an agent which increases the expression of genes encoding an H3K27me3-specific demethylase, or increases the activity of human H3K27me3-specific demethylase.

The present disclosure relates generally to compositions and methods for treating cancer and neoplastic disease.
