The present disclosure relates to nucleic acid vaccine compositions and methods for preventing or treating pathological conditions, such as cancer or infectious disease. Further, the disclosure provides methods for more efficient production of antigens via mRNA containing one or more non-conventional start codons to promote multiplex initiation of translation in eukaryotic cells.

Engineered FGF1 and FGF2 polypeptides, polynucleotides encoding these polypeptides and DNA constructs, vectors and compositions including these engineered polypeptides are provided herein. The engineered FGF1 and FGF2 polypeptides are more stable than their wild-type counterparts and may be more effective at treating a variety of conditions that FGF1 and FGF2 are useful for treating such as wound healing.

Disclosed herein are peptide analogs of human FGF. These peptide analogs exhibit improved therapeutic activity and fewer side effects when used in humans. Also disclosed are pharmaceutical or cosmetic compositions comprising the FGF analogs and pharmaceutically or cosmetically acceptable carriers or excipients. Also provided are methods of treating or preventing a disease in a subject that involves administering to the subject the disclosed FGF analogs.

The present invention relates in part to nucleic acids, including nucleic acids encoding proteins, therapeutics and cosmetics comprising nucleic acids, methods for delivering nucleic acids to cells, tissues, organs, and patients, methods for inducing cells to express proteins using nucleic acids, methods, kits and devices for transfecting, gene editing, and reprogramming cells, and cells, organisms, therapeutics, and cosmetics produced using these methods, kits, and devices.

The invention provides an isolated thermostable polypeptide possessing FGF2 activity and having at least 85% sequence identity to SEQ ID NO: 2 (FGF2 wt) or a functional fragment thereof, and comprising at least one amino acid substitution R31L and the use thereof in the cell biology research, regenerative medicine and related medical applications or cosmetics. Further it discloses a culture medium comprising subjected FGF2 suitable for culturing a human pluripotent stem cells involving both human embryonic stem cells and induced pluripotent stem cells.

The embodiments herein disclose a method for synthesizing antagonistic peptide VEGF and bFGF. The method comprises synthesizing the antagonistic peptide for VEGF and bFGF and analyzing the purity of peptides. The quality of antagonistic peptide for VEGF and bFGF is analyzed by HPLC chromatogram and Mass spectrometry analysis. The biochemical activity of the antagonistic peptide for VEGF and bFGF is analyzed by competitive binding assay, cell proliferation assay, Matrigel assay for anti-angiogenic activity analysis, histopathological staining and Western blot analysis. The competitive binding assay of antagonistic peptide for VEGF and bFGF illustrate that peptides binds with cell receptors at a concentration of 2000 ng/ml. The cell proliferation assay illustrates that cell growth is arrested when antagonistic peptide for VEGF and bFGF are at a concentration of 2000 ng/ml. The anti-angiogenic activity analysis illustrates that angiogenesis is arrested when the concentration of antagonistic peptide for VEGF and bFGF is 2000 ng/ml.

The present disclosure relates to a highly stable basic fibroblast growth factor mutant, and a use thereof. Specifically, the present disclosure provides: a highly stable basic fibroblast growth factor mutant, in which two or more amino acids in an amino acid sequence of SEQ ID NO.: 1 are substituted with serine and one or more amino acids are substituted with cysteine; a DNA base sequence encoding the bFGF mutant; an expression vector including the DNA base sequence; a transformant transformed by the expression vector; a method of producing the bFGF mutant; and a composition including the bFGF mutant as an active ingredient. According to the present disclosure, the bFGF mutant of the present disclosure has excellent stability in an aqueous solution state and excellent thermal stability, and thus it is possible to produce functional cosmetics and skin inflammation medicines which do not lose activity, even during distribution and storage.

Provided are a mutated nucleic acid molecule of a recombinant human-basic fibroblast growth factor (rh-bFGF), a pharmaceutical composition of the rh-bFGF, and a use thereof.

Provided are a method for producing a soluble recombinant human-basic fibroblast growth factor (rh-bFGF), a recombinant human-basic fibroblast growth factor (rh-bFGF) obtained by the method, and a mutated nucleic acid molecule encoding the recombinant human-basic fibroblast growth factor (rh-bFGF).

The present invention relates to a culture solution of MSCs derived from a fetus in amniotic fluid, and more specifically, to a composition for promoting hair growth or preventing hair loss, which includes a culture solution of MSCs overexpressing a reprogramming factor Nanog and derived from a fetus in amniotic fluid as an active ingredient. In addition, the present invention relates to a method for preparing the composition, which includes culturing Nanog-introduced MSCs derived from a fetus in amniotic fluid in a conditioned medium and collecting the culture solution. The conditioned medium composition according to the present invention exhibits a hair growth promoting effect, and thus is able to be used as cosmetic and pharmaceutical compositions for promoting hair growth.
