The preset invention relates to a new approach for treating a cancer, particularly a malignant tumor, a multidrug-resistant (MDR) cancer, a recurrent cancer or a metastatic cancer, using a specific cationic antimicrobial peptide (CAP), tilapia piscidin 4 (TP4), which is derived from Nile Tilapia (Oreochromis niloticus). Also provided is a method for treating a breast cancer, particularly triple negative breast cancer (TNBC) with TP4.

A method for treating a biological cell is disclosed. The method administers a mixture of a chemotherapeutic drug and a co-drug that facilitates delivery of the chemotherapeutic drug to the nucleus of the cell. Examples of co-drugs include cationic polymers, cationic lipids and cationic proteins. Cationic polymers include a polyethyleneimine (PEI), polylysine, a polybetaaminoester (PBAE), an ε-polylysine (EPL) including ε-poly-L-lysine (e-PLL), a polyarginine peptide, chitosan, a polyamidoamine dendrimer (PAMAM). Cationic lipids include 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP). Cationic proteins include protamine.

A method for improving a skin condition of a subject in need thereof includes administering to the subject a composition including a bioactive compound. The bioactive compound is a peptide, and includes at least one amino acid sequence as set forth in SEQ ID NO: 1 to SEQ ID NO: 11. Each of the amino acid sequence is a peptide of fish skin.

Structurally stabilized, e.g., stapled, peptides with the ability to translocate through microbial cell membranes to the interior of microbial cells and exert a biological activity there are provided, as are methods of designing, making and using such peptides.

The present invention is directed to a method for differentiating between ASD phenotype 1, phenotype 2 and other ASD patients, wherein the method comprises: administering an Nrf2-activator to a subject, and identifying the subject as an ASD phenotype 1 patient if the subject shows a negative response, as a phenotype 2 patient if he shows a positive response and as another ASD patient if he does not show a positive nor a negative response, wherein the subject is a patient previously diagnosed with idiopathic ASD or a subject displaying clinical signs of ASD. Likewise, the present invention is directed to an Nrf2-activator for use in differentiating between autism spectrum disorder (ASD) phenotype 1 patients, phenotype 2 patients and other ASD patients, wherein the Nrf2-activator is administered to a subject, wherein a phenotype 1 patient is identified by a negative response, a phenotype 2 patient is identified by a positive response and other ASD patients are identified by the absence of a positive and a negative wherein the subject is a patient previously diagnosed with idiopathic ASD or a subject displaying clinical signs of ASD.

A method of constructing a zebrafish notch1a mutant using CRISPR/Cas9 technique. The method includes: determining a target for knocking out notch1a; using primers T7-notch1a-sfd and tracr rev for PCR amplification with a pUC19-gRNA scaffold plasmid as a template; transcribing PCR product in vitro followed by purification to obtain gRNA; and microinjecting the gRNA and a Cas9 mRNA into a zebrafish embryo followed by culture to obtain an notch1a mutant of stable inheritance. The invention selects a specific target and utilizes CRISPR/Cas9 technique to knock out the notch1a in the zebrafish without destroying other genes, generating the zebrafish notch1a mutant. Moreover, the invention also discloses the phenotype of the zebrafish notch1a mutant, which plays a significant role in studying the effect of the Notch1a receptor in the Notch signaling pathway.

The present invention relates to the novel trypsin ZT isoforms. In particular, the invention relates to the use of trypsin ZT isoforms in medical devices, pharmaceuticals and cosmetics.
