  • Patent number: 11234993
    Abstract: The present invention provides an alcohol extract of Ajuga taiwanensis Nakai ex Murata exhibits significant effects on inhibiting the senescence in human WI-38 lung fibroblasts and human dermal fibroblasts. Moreover, the alcohol extract of A. taiwanensis is able to suppress the expression of the cofilin-1, a protein involved in actin dynamics and cell morphology and found to be increased in senescent cells. Suppression effect of cell senescence by this herb extract is more efficient in mild concentration without over-inhibition of cell viability and growth.

  • Patent number: 9873721
    Abstract: A fluorescent fusion protein is provided. The fluorescent fusion protein of the invention comprises a first fluorescent protein with first emission wavelength, a second fluorescent protein with second excitation wavelength and second emission wavelength, and a linker peptide linking the first fusion protein and the second fusion protein, wherein the first emission wavelength overlaps the second excitation wavelength so that the second fluorescent protein exhibits the second emission wavelength after receiving energy. The fluorescent fusion protein of the invention exhibits a stronger fluorescence in the absence of bilivirdin (BV).

  • Patent number: 8574852
    Abstract: The present invention discloses a concept that the expression level of cofilin may reflect the senescent condition of a cell or tissue. According to the findings in present invention, a method for determining the cellular senescent condition in a cell or tissue sample by evaluating the expression level of cofilin is provided. The detection of the expression level of cofilin is also used to screen an effective compound or composition for regulating the senescent condition in target cells.

  • Publication number: 20110217239
    Abstract: Disclosed herein are systems and methods for evaluating a protein of interest on growth inhibition of a tumor while following the tumor in vivo or in vitro through a co-expressed visible marker. The present disclosure provides an expression composition for stably transforming cells, preferably tumor cells. The expression composition includes two vectors respectively include polynucleotides encoding a protein of interest and a visible marker, wherein each polynucleotide is operably linked to a tet-on system such that the protein of interest and the visible marker are co-expressed upon activation of the tet-on system. The present disclosure also provides stably transfected cell lines, which may be used to access real-time biological processes, including tumor cell proliferation.
