The present disclosure provides, inter alia, a recombinant engineered deubiquitinase (DUB) and methods for treating or ameliorating an inherited ion channelopathy, such as long QT syndrome, Brugada syndrome, or cystic fibrosis, in a subject. Further provided are methods for screening mutations causing such inherited ion channelopathies for a trafficking-deficient mutation that is treatable by the recombinant engineered DUB disclosed herein.

Provided herein are DNA targeting systems comprising a site-directed modifying polypeptide and a Tumor Necrosis Factor Alpha-induced Protein 3 (TNFAIP3)-specific guide RNA or a Suppressor of Cytokine Signaling 1 (SOCS1)-specific guide RNA, and uses thereof.

The present invention identifies biomarkers that are diagnostic of nerve cell injury and/or neuronal disorders. Detection of different biomarkers of the invention are also diagnostic of the degree of severity of nerve injury, the cell(s) involved in the injury, and the subcellular localization of the injury.

Described are methods for removing a proteolytic cleavage site, the HCHWA-D mutation or the amino acids encoded by a trinucleotide repeat expansion from a protein comprising providing a cell that expresses pre-mRNA encoding the protein with an anti-sense oligonucleotide that induces skipping of the exonic sequence that comprises the proteolytic cleavage site, HCHWA-D mutation or trinucleotide repeat expansion, respectively, the method further comprising allowing translation of mRNA produced from the pre-mRNA.

Reduction of ocular scarring is accomplished from the discovery that silencing of the expression of USP10 in the area of a wound under healing will reduce the accumulation of integrin on the cell's surface and activation of the fibrotic growth factor TGF, thereby preventing ocular scarring.

The invention relates to means and methods for removing a proteolytic cleavage site from a protein comprising providing a cell that expresses pre-mRNA encoding the protein with an anti-sense oligonucleotide that induces skipping of the exonic sequence that encodes the proteolytic cleavage site, the method further comprising allowing translation of mRNA produced from the pre-mRNA.

This present technology relates to the use of inflammation-enabling polypeptides (or their coding sequences) to screen for agents useful for the prevention, treatment and/or alleviations of symptoms associated with an inflammatory disorder, to identify individuals susceptible of developing an exacerbated inflammatory response as well as to determine if a therapeutic regimen is capable of preventing, treating or alleviating the symptoms associated to an inflammatory disorder in an individual. The present technology also provides methods for preventing, treating and/or alleviating the symptoms associated to an inflammatory condition based on the inhibition of expression or activity of the inflammation-enabling targets.

The disclosure relates to methods for treating cancers (e.g., cancers having a BRCA1 and/or BRCA2 mutation(s)) by administering to the subject an effective amount of a ubiquitin-specific protease 1 (USP1) inhibitor.
