Protocol for rAAVrh.74-SaCas9/gRNA Vector-Mediated Postnatal Cardiac Gene Editing in mdx/utrophin+/- Mice

Experiment Tags: CRISPR, Genome Engineering, Cardiac Gene Editing, rAAV Delivery, Dystrophin Restoration

Experiment Summary: This protocol describes how to use the clustered, regularly interspaced, short, palindromic repeat (CRISPR) system to perform postnatal cardiac gene editing in mdx/utrophin+/- mice. Specifically, the protocol uses the Staphylococcus aureus CRISPR-associated protein 9 (SaCas9) and guide RNAs (gRNAs) delivered via recombinant adeno-associated virus (rAAV) serotype rh.74 (rAAVrh.74) to carry out the gene editing. Restoring dystrophin expression in these mice's cardiac muscles is the main goal in hopes of developing a treatment for Duchenne muscular dystrophy (DMD).

Intraductal Injection of Adenoviral Cre for Temporally Controlled Breast Cancer Modeling in Mice

Experiment Tags: Breast Cancer, Mouse Model, Intraductal Injection, Adenoviral Cre, Temporal Control

Experiment Summary: This protocol outlines a technique for injecting adenoviral Cre (Ad-Cre) intraductally into mice mammary glands to create animal models of breast cancer. By employing cell-type-specific promoters to target mammary epithelial cells (MECs), this strategy enables fine temporal control of cancer induction and cell-type specificity. The process is described in the protocol, which includes creating and caring for floxed mice, monitoring the growth of breast tumors, and providing postoperative care.

Protocol for Mitochondria Transfer between Mesenchymal Stem Cells and Glioblastoma Stem Cells

Experiment Tags: Mitochondria Transfer, Mesenchymal Stem Cells, Glioblastoma Stem Cells, Cell Interaction, Cell Biology.

Experiment Summary: This protocol facilitates the transfer of mitochondria from mesenchymal stem cells (MSCs) to glioblastoma stem cells (GSCs). This protocol allows for the investigation of the effects of mitochondria on GSC metabolism, proliferation, and response to therapy by isolating mitochondria from MSCs and transferring them to GSCs.

Recombinase-Mediated Cassette Exchange for Structure-Function Studies in Mouse Embryonic Stem Cells

Experiment Tags: RMCE, Mouse Embryonic Stem Cells, Structure-Function Studies, Recombinase-Mediated Cassette Exchange, Gene Targeting, ROSALUC Mice, R26-iPSC Mice, pRMCE-DV1, Cre-Excised pRMCE-DV1, pCAG-FlpE-IRES-Puro-pA, Gateway pDONR221 Vector.

Experiment Summary: This protocol describes how to employ recombinase-mediated cassette exchange (RMCE) to perform structure-function research in mouse embryonic stem cells (mESCs). The process entails separating KO mESCs that are compatible with RMCE, creating a targeting vector that is compatible with RMCE, and using RMCE to target rescue constructs to the ROSA26 locus using mESCs.

Ex Vivo Infection of Live Tissue with Oncolytic Viruses

Experiment Tags: Oncolytic viruses, tissue processing, viral infection, fluorescence microscopy, luciferase expression, plaque assay

Experiment Summary: As cancer treatments, oncolytic viruses (OVs) have potential, and determining whether living tissue specimens are infectious ex vivo prior to treatment offers a distinct benefit. This protocol describes the steps involved in preparing tissues for oncolytic virus ex vivo infection and the subsequent measurement of viral activity.

Optimization of CRISPR-Cas9 Gene Editing in Brown Adipose Tissue Using Lentivirus and AAV Delivery Systems

Experiment Tags: CRISPR-Cas9, Gene Editing, Lentivirus, AAV, Brown Adipose Tissue, Mouse Model

Experiment Summary: This Protocol optimizes CRISPR-Cas9 gene editing in brown adipose tissue (BAT) using lentivirus and AAV systems. Ucp1-Cre/Cas9 mice are used in in vivo research after screening effective sgRNAs in cultured cells and cloning them into AAV vectors. Western blot analysis is used to validate the effectiveness of gene deletion. By using this approach, the biology of BAT and its potential for treatment in metabolic diseases are better understood.

Modeling Hepatitis B Virus Infection in Non-Hepatic 293T-NE-3NRs Cells

Experiment Tags: HBV Infection Model, cell culture, HepG2, Co-culture

Experiment Summary: Current HBV research primarily focuses on hepatocytes, limiting insights into HBV-related pathology in non-hepatic tissues. This study introduces a protocol using non-hepatic 293T and hepatoma cells to investigate HBV infection. Two HBV infection methods were developed based on 293T-NE-3NRs.
