Provided is an improved cell-permeable nuclear import inhibitor (iCP-NI) for inhibition of cytokine storm or an inflammatory disease, in which solubility and stability are improved by introducing an advanced macromolecule transduction domain (aMTD)-based therapeuticmolecule systemic delivery technology (TSDT) into a cell-permeable nuclear import inhibitor (CP-NI, cSN50.1 peptide). The improved cell-permeable nuclear import inhibitor synthetic peptide according to the present disclosure more efficiently blocks signal transduction mediated by stress-responsive transcription factors (SRTFs) including NF-κB, based on remarkable cell permeability, and thus it may be used as an excellent prophylactic or therapeutic agent for cytokine storm or inflammatory diseases.

A method for producing an objective protein by using animal cells as an expression host is provided. The objective protein is produced by culturing animal cells having an objective protein-producing ability in the presence of an L-cysteine derivative such as (2RS,4R)-2-methyl-2,4-thiazolidinedicarboxylic acid 2-ethyl ester.

The present disclosure relates to a fusion protein of Z-domain and calsequestrin having improved reactivity, stability, and antibody recovery, and a method of isolating and purifying antibodies using the same. Specifically, the present disclosure relates to: a nucleic acid encoding a fusion protein of Z-domain and calsequestrin having improved reactivity, stability, and antibody recovery; a recombinant expression vector including the nucleic acid; a host cell transformed with the recombinant expression vector; and a method of isolating and purifying antibodies by using the fusion protein of Z-domain and calsequestrin having improved reactivity, stability, antibody recovery, and purity.

The present disclosure relates to a multi-functional nanoparticle targeted to breast cancer, a preparation method and use thereof. The multi-functional nanoparticle includes a targeting carrier and a medicament loaded on the targeting carrier; and the targeting carrier is made from recombinant ferritin. Cell experiments verify that the multi-functional nanoparticle has better efficacy and drug release capacity for cancer cells than those of conventional ferritin as a vector. Moreover, the drug delivery system can further achieve optical imaging of tumor cells by loading quantum dots, thus playing a role in cancer diagnosis and treatment.

Disclosed are: a method for activating a helper T cell, which comprises the step of adding a WT1 peptide to an antigen-presenting cell to activate the helper T cell, wherein the WT1 peptide is capable of binding to any one selected from an HLA-DRB1*1501 molecule, an HLA-DPB1*0901 molecule and an HLA-DPB1*0501 molecule; a composition for use in the method; a therapeutic and/or prophylactic method for cancer by activating a helper T cell; a pharmaceutical composition for use in the therapeutic and/or prophylactic method; and others.

The present invention relates to compositions and methods for treating cancer, particularly to agents that inhibit the expression and/or activity of the protein second mitochondria-derived activator of caspase/direct inhibitor of apoptosis-binding protein with low pI (SMAC/Diablo). The inhibiting agents include RNA interference molecules silencing the expression of SMAC/Diablo and peptides modulating its interactions within the cell nucleus and mitochondria. The methods and agents of the present invention are useful in treating cancers associated with overexpression of SMAC/Diablo.

Disclosed are compositions and methods for treating heart failure and cardiac damage that can lead to heart failure if left untreated comprising administering to a subject in need thereof a composition comprising an HSP60 derived peptide and an adjuvant.

This invention relates to polynucleotides encoding mini-dystrophin proteins, viral vectors comprising the same, and methods of using the same for delivery of mini-dystrophin to a cell or a subject.

This invention provides WT1 peptides and methods of treating, reducing the incidence of, and inducing immune responses against a WT1-expressing cancer, comprising same.
