Description

Technical Field

[0001] The present invention discloses a composition for skin anti-aging, skin whitening, skin texture improvement, inhibition of lipofuscin accumulation and / or removal of lipofuscin, which contains a metalloprotease derived from a Chryseobacterium strain as an active ingredient.

Background Art

[0002] Lipofuscin is a metabolite related to aging and oxidative stress and exists in the form of an insoluble pigment in cells. It is known that lipofuscin is generated by the accumulation of insufficiently decomposed substances in cells due to oxidative stress and cell deterioration. The more lipofuscin accumulates in cells, the more the cell function declines and aging is promoted.

[0003] The heart of the elderly appears brown and atrophied due to an increase in pigmentation by lipofuscin, which is called "brown atrophy of the heart". Similar pigmentation may also be seen in the liver, which is called "brown atrophy of the liver". Furthermore, cases of pigmentation by lipofuscin in the heart, liver, and kidneys have been reported in patients with wasting diseases such as cancer and chronic severe pulmonary tuberculosis. On the other hand, pigmentation such as liver spots and senile plaques is a prominent sign of skin aging, and these are phenomena caused by the accumulation of lipofuscin. Therefore, lipofuscin is also called "senile plaque in the body". Thus, inhibiting the production and accumulation of lipofuscin in skin cells is extremely important in preventing skin aging.

[0004] As mentioned earlier, lipofuscin, which is naturally produced during cellular metabolism, accumulates in cells more frequently with age, as well as due to a decline in cellular function or repeated exposure to external toxins. Furthermore, accumulated lipofuscin inhibits normal cellular function and accelerates aging. Lipofuscin is present not only in skin cells but also in the liver, kidneys, myocardium, retina, adrenal glands, nerve cells, and ganglion cells, and is known to accumulate in important organs, causing various degenerative diseases. For example, the accumulation of lipofuscin in the myocardium can degrade it and potentially cause myocardial infarction, while the accumulation of lipofuscin in the retina and nerve cells may cause macular degeneration and Alzheimer's disease. In addition, accumulation in hormone-secreting organs such as the adrenal glands, liver, and pituitary gland may inhibit the metabolic function of hormones such as growth hormone and sex hormones.

[0005] The presence of lipofuscin observed in the skin is considered a sign of aging, and research is underway to find cosmetic ingredients that can help mitigate it. However, to date, no cosmetic ingredients that directly break down lipofuscin are known, and only indirect effects through specific ingredients that reduce oxidative stress and promote skin cell regeneration are expected.

[0084] The present disclosure will be described in more detail below with reference to examples. These examples are merely illustrative and it will be obvious to those with ordinary skill in the art that the scope of the present disclosure is not limited in any way by these examples.

[0085] [Example 1] Preparation of culture solution for Chryseobacterium strains In this embodiment, a culture medium of the Chryseobacterium strain was prepared as follows, using the Chryseobacterium camelliae strain as the Chryseobacterium strain. The Chryseobacterium camelliae strain deposited under accession number KCCM11883P was the Chryseobacterium camelliae dorsoni-HT1 strain. The strain can be obtained according to the isolation and identification method described below, as described in Patent Document 2. This document is incorporated herein by reference in its entirety.

[0086] (1) Isolation of microorganisms from green tea To select microorganisms with plant-derived keratin-degrading activity, microorganisms were cultured at 30°C or 37°C using a minimal liquid medium (M9 medium containing 0.5% soluble keratin: CaCl2 0.015 g / L, Na2HPO4 6.78 g / L, KH2PO4 3 g / L, NaCl 0.5 g / L, MgSO4 0.5 g / L) with keratin as the carbon and nitrogen sources.

[0087] The aforementioned method for selecting microorganisms using minimal culture medium is a method for selecting target microorganisms based on their growth rate. Since microorganisms with low keratinase activity are naturally removed during the culture stage, it is possible to select active microorganisms that possess high-activity enzymes. This suggests that microorganisms that can grow in minimal culture medium possess keratinase activity.

[0088] Therefore, microorganisms with keratin-degrading activity were isolated from green tea grown in the Dolseongi tea garden on Jeju Island, South Korea, using a limited culture medium.

[0089] (2) Identification of isolated microorganisms To identify the isolated microorganisms possessing keratinase activity, their species and genus names were determined by analyzing the DNA sequences encoding the 16S ribosomal RNA sub-sequences of the microorganisms.

[0090] Microorganisms were cultured in liquid medium, and then their gene DNA was extracted. This DNA was then amplified by PCR (polymerase chain reaction) using the 27F(5'-AGAGTTTGATCMTGGCTCAG-3'; SEQ ID NO: 1) / 1492R(5'-TACGGYTACCTTGTTACGACTT-3'; SEQ ID NO: 2) primer, which is commonly used for bacterial identification, and its sequence was analyzed.

[0091] Sequence analysis revealed 99% homology to the 16S rRNA partial sequence of Chryseobacterium camelliae strain THG C4-1 (KACC16985; Sequence accession no. (16S rRNA) JX843771) and 98% homology to the 16S rRNA partial sequence of Chryseobacterium taiwanense.

[0092] Therefore, the novel microbial strain isolated and cultured was confirmed to be Chryseobacterium camelliae by molecular phylogenetic analysis based on its 16S rDNA sequence, and was named Chryseobacterium camelliae Dolsongi-HT1. The novel microbial strain was deposited with the Korea Center for Microbial Conservation (KCCM), the depositary institution, on September 1, 2016, under accession number KCCM11883P. Figure 1 shows the 16S rDNA partial sequence of the Chryseobacterium camelliae Dolsongi-HT1 strain (SEQ ID NO: 3).

[0093] (3) Production of microbial culture solution Chryseobacterium camelliae dolsoni-HT1 strain, derived from green tea, was seed-cultured for 15 hours. Subsequently, 10 mL of the cultured strain was inoculated into 1 L of optimal medium (1% Tryptone / 1% NaCl / 0.5% Skim milk) and cultured at 30°C and 200 rpm for 15 hours. After culturing, a culture solution from which microorganisms had been removed was obtained.

[0094] [Example 2] Enzyme purification and sequence analysis from culture medium of Chryseobacterium strains. From the culture medium of the Chryseobacterium strain prepared in Example 1, proteins with a size of 10 kDa or larger were obtained by ultrafiltration using a 10 kDa cut-off size filter. To select proteins with proteolytic activity, the proteins were isolated using ion exchange resin (Q-sepharose(R) HP column, Cytica, Marlborough, MA, USA) and analyzed by mass spectrometer (Q Exactive). TM Proteins in the active fraction were analyzed using a Plus mass spectrometer (Thermo Fisher Scientific, Waltham, MA, USA). A total of 120 proteins were analyzed.

[0095] Since the whole genome of the Chryseobacterium cameliae dolsoni-HT1 strain had already undergone whole genome analysis, eight proteins named proteases were selected from the analyzed proteins by comparing the whole genome analysis results with the protein analysis results. The eight selected proteins were converted into recombinant proteins as follows, and their keratin-degrading activity was compared.

[0096] First, the gene sequences of the eight proteins listed in Table 1 below were amplified by PCR using forward and reverse primers, and then each enzyme was expressed using the Bacillus subtilis Secrection protein expression system (TaKaRa(R)). The vector used for the recombinant protein production was the pBE-S vector, and the genes were introduced into the vector using the In-Fusion Cloning system. The gene transfer vector was introduced into the host B. subtilis RIK1285. To express the protein, the expression strain was cultured at 37°C for 24 hours. After culturing, the microbial cells were removed, the culture medium was collected, concentrated by ultrafiltration, and then freeze-dried to obtain the sample.

[0097] [Table 1]

[0098] Keratinase activity was measured using 0.5% (wt / v) keratin azure and pH 8.0 Tris-HCl buffer. When keratin azure is broken down by keratinase, the azure dye is released, and the reaction solution turns blue. Therefore, to compare the activity levels, the absorbance at 595 nm was measured (absorbance 0.01 = 1 unit).

[0099] As a result, keratinase activity was observed in MetalloP and ContP1 from two protein samples, numbers 5 and 6, confirming that MetalloP and ContP1 have an effect of improving skin texture through exfoliation (see Figure 2). In particular, MetalloP showed remarkably high keratinase activity. On the other hand, ContP2 from protein sample number 4 had the highest content among the purified proteins, but showed no keratinase activity at all.

[0100] As described above, enzymes possessing keratinase activity were purified from the Chryseobacterium camelliae dolsoni-HT1 strain isolated from green tea leaves, and their sequences were compared with the NCBI database. This confirmed that MetalloP and ContP1 are enzymes belonging to the metalloprotease series. The purified enzyme MetalloP was confirmed to have the sequence of Sequence ID No. 20.

[0101] [Example 3] Evaluation of lipofuscin-degrading activity of metalloproteinases derived from Chryseobacterium strains. The enzymes MetalloP, ContP1, and ContP2, which were overexpressed in recombinant bacterial strains prepared in Example 2, were used to treat lipofuscin-inducing cells as follows, and their lipofuscin removal effects were evaluated. ContP1 is an enzyme with approximately 50% of the keratin-degrading effect compared to MetalloP, and ContP2 is an enzyme with no keratin-degrading effect.

[0102] Fibroblasts were grown to 90% confluent, and then cultured in growth medium with 40 μM leupeptin, 45 μM FeCl3, and 10 μM H2O2 for 10 days to accumulate lipofuscin within the cells. The culture medium was changed every two days. After 10 days of culture, each sample was treated with a 10 ppm solution for 7 days. The degree of lipofuscin degradation was measured using a confocal laser scanning microscope (LSM 980, Carl Zeiss, Oberkochen, Germany) equipped with a FITC (fluorescein isothiocyanate) 540 / 40 filter.

[0103] As a result, as shown in Figure 3, lipofuscin removal was observed in the experimental groups (MetalloP, ContP1) in which cells with accumulated lipofuscin were treated with metalloproteinases. In particular, in the experimental group treated with MetalloP, the accumulated lipofuscin was completely removed, confirming that MetalloP exhibited the most superior lipofuscin degradation activity.
