The application provides a reduction-responsive nano delivery system and application thereof in preparation of a drug for treating drug-resistant tumors, and belongs to the pharmaceutical field. The application constructs a reduction-responsive branched copolymer functionalized by pegylation and deoxycholic acid (DA) (referred to as: pegylated branched poly(HPMA-DA)), which can effectively encapsulate small molecule drugs to form a nano delivery system. Experiments prove that the nano delivery system can be taken up by tumor cells, has good tumor targeting, and exhibits excellent anti-tumor effect in tumor xenografts (CDX) derived from non-small cell lung cancer (NSCLC) chemoresistant cell lines and patient-derived xenograft mouse models (PDX). The pegylated branched poly(HPMA-DA) provided by the application has wide application prospect in preparation of a drug carrier, and the nano delivery system provided by the application has wide application prospect in preparation of a drug for treating cancer.

The invention described herein provides non-HLA matched humanized mouse model (e.g., NSG mouse model) with patient-derived xenograft (PDX), as well as methods of making and using the same.

Disclosed herein include methods and compositions for pig-to-human organ xenotransplantation using genetically modified pigs with triple-gene knockouts and human gene insertions. In some embodiments, the organ xenotransplantation is a pig-to-human kidney xenotransplantation demonstrating the restoration of renal function. Also disclosed are methods and compositions for preventing acute rejection and / or reactivation of porcine herpesvirus, which contributes to advancing xenotransplantation as a viable solution to the global organ shortage.

This document provides methods and materials involved in reducing cardiac xenograft rejection. For example, methods and materials for preparing transgenic pigs expressing reduced or no endogenous Sda or SDa-like glycans derived from the porcine β1,4 N-acetyl-galactosaminyl transferase 2 (B4GALNT2) glycosyltransferase and / or reduced or no endogenous α-Gal antigens, methods and materials for modifying the xenograft recipient's immunological response to non-Gal antigens (e.g. CD46, CD59, CD9, PROCR, and ANXA2) to reduce cardiac xenograft rejection, and methods and materials for monitoring the progress of xenotransplant immunologic rejection are provided.

Creating a single-cell methylation atlas characterizing an organ of a donor by clustering methylated single-nuclei whole genome sequences (m-snWGS) from a biopsy of the organ based at least in part on differentially methylated patterns of the m-snWGS, assigning a cell type for each cluster based at least in part on correlation of known cell type markers of the organ with the differentially methylated patterns of the m-snWGS; and providing the atlas to include a database with genomic sequences based at least in part on the m-snWGS, methylation patterns of the genomic sequences based at least in part on the m-snWGS, and cell type designation for the genomic sequences based at least in part on the cell type assigned for each cluster.

The present invention relates to compounds of formula 1 or 2,wherein R1 and R3 are purine or a purine analog and R2 and R4 are a small functional group. The invention also relates to intermediates of the synthesis of compounds of formula 1 or 2. Compounds of formula 1 or 2 are Janus kinase inhibitors and thus useful in the treatment of a disease, particularly an autoimmune disease, cancer, Alzheimer's disease or useful in preventing the rejection of an allograft or xenograft.

The present application relates to a bi-functional therapeutic for treating cancer that includes a targeting component which targets a tumor-associated antigen and an enzyme which, when delivered to a tumor by said targeting component, converts the tumor phenotype to that of an incompatible allograft or xenograft. The enzyme is coupled to the targeting component. Also disclosed is a method for treating cancer comprising administering the bi-functional therapeutic.
