Disclosed here are polypeptides derived from the HD2 domain of human B-cell CLL/lymphoma 9 (BCL9) protein and variants thereof, as well as their use in the diagnosis, prevention, and/or treatment of a disease or disorder. Also disclosed are methods of generating such polypeptides and variants thereof.

A peptoid compound, a manufacturing method of a peptoid compound, an oligomer, a pharmaceutical composition, use of the pharmaceutical composition in the preparation of a medicament for detecting or diagnosing a disease related to tyrosine kinase HER2, and a kit for identifying circulating tumor cells are provided, the peptoid compound includes: a cysteine (Cys) subunit, a butanediamine (Nlys) subunit, a 3,4-methylenedioxybenzylamine (Npip) subunit, a 3-aminopropanic acid (Nce) subunit and a 1-naphthylamine (Na) subunit, and both the peptoid compound and the oligomer have a strong ability to bind to HER2 protein on surfaces of circulating tumor cells (CTCs), and a technology of diagnosing breast cancer on the basis of the peptoid compound can realize non-invasive and label-free rapid diagnosis, in addition, the methods for synthesizing the peptoid compound and the oligomer are simple, the preparation efficiency is high, and the production cost is low.

The invention relates to a recombinant Modified Vaccinia Virus Ankara (MVA) expressing a TAA and the costimulatory molecule 4-1BBL for use in (i) the prevention of recurrence of a solid tumor, wherein the recombinant MVA is intratumorally administered to the solid tumor, or (ii) the treatment, prevention and/or prevention of recurrence of a tumor, wherein the recombinant MVA is intratumorally administered to another solid tumor.

Methods of treating hepatic steatosis involve administering to a subject a DENND5B inhibitor, thereby reducing the expression of and/or activity of DENND5B in liver of the subject. The DENND5B inhibitor can include antisense oligonucleotide (ASO), CRISPR interference (CRISPRi), miRNA, siRNA, locked nucleic acid (LNA) nucleotides, or a combination thereof.

Compositions and methods for treating neurofibromatic disorders are provided herein, such as expressing Merlin protein or a functional fragment thereof from a viral vector.

Compositions, non-viral vectors, recombinant viruses, and recombinant viral vectors for inhibiting ΔFosB expression or activity in a cell and for treating dyskinesia in a subject (e.g., a human patient having Parkinson's disease and Levodopa-induced dyskinesia) include a nucleic acid sequence encoding a shRNA specific for ΔFosB. Methods of using these compositions, non-viral vectors, recombinant viruses, and recombinant viral vectors are also described herein. These compositions, non-viral vectors, recombinant viruses, and recombinant viral vectors and methods of use provide novel therapies for dyskinesia based on the reduction of ΔFosB expression and/or activity.

Methods for treating cancer with a stabilized BCL9 peptide are encompassed, wherein the stabilized peptide comprises a portion of the HD2 domain of the BCL9 protein containing a hydrocarbon crosslinker generated using α, α-disubstituted amino acids.
