이전에 본 발명자들은 단핵백혈구(monocyte), 호중구(neutrophil) 등과 같은 백혈구 세포를 증가시키는 펩타이드 리간드(Trp-Lys-Tyr-Met-Val-D-Met-NH2: 서열번호 1, 이하, “WKYMVm 펩타이드”라 함)를 발표한바 있다(Bae et al., 1999, J. Leukoc. Biol. 65, 241-248). 따라서 본 발명자들은 WKYMVm 펩타이드를 이용하여 면역반응을 촉진시키는 동시에 항암제를 병용투여하여 항암제의 사용량을 줄이면서 항암 효과는 증가시킬 수 있는 방법에 대하여 연구한 결과 본 발명을 완성하게 되었다.Previously, we have described peptide ligands (Trp-Lys-Tyr-Met-Val-D-Met-NH 2 : SEQ ID NO: 1, hereinafter, “WKYMVm that increase leukocyte cells such as monocytes, neutrophils, etc.). Peptides ”(Bae et al., 1999, J. Leukoc. Biol. 65, 241-248). Therefore, the present inventors have completed the present invention as a result of research on a method of increasing the anticancer effect while reducing the amount of anticancer agent by simultaneously using an anticancer agent while promoting an immune response using the WKYMVm peptide.

대표적인 항암제 중 하나인 5-플루오로우라실(5-fluorouracil, 5-FU)은 DNA의 전구물질인 티민과 유사한 구조를 가지고 있어 암세포의 DNA 합성을 저해하며 항암효과를 나타내기 때문에, 위암을 비롯한 소화기계 암에서 널리 사용되고 있다. 그러나 골수저하, 설사 등의 부작용으로 인한 한계를 가지고 있다. 또한 수지상세포는 체내의 면역반응을 촉진하여 면역항암치료에 사용할 수 있을 것이라는 가능성이 제시되고 있어 많은 연구가 진행되고 있지만, 아직 항암 효과 등에 있어 미비한 실정이다.One of the representative anticancer drugs, 5-fluorouracil (5-FU) has a structure similar to that of thymine, a precursor of DNA, which inhibits DNA synthesis of cancer cells and shows anticancer effects. Widely used in mechanical arms. However, there are limitations due to side effects such as bone marrow depression and diarrhea. In addition, dendritic cells have been suggested to be able to be used for immune chemotherapy by promoting the immune response in the body, many studies have been conducted, but the situation is still insufficient in the anti-cancer effect.

따라서 본 발명자들은 체내의 면역반응을 촉진할 수 있는 WKYMVm 펩타이드 및 수지상세포와 항암제인 5-플루오로우라실을 병용투여하여 항암 치료에 사용하고자 하였다.Therefore, the present inventors tried to use WKYMVm peptide and dendritic cells that can promote the immune response in the body and 5-fluorouracil, an anticancer agent, for use in anticancer treatment.

본 발명의 일 실시예에서는 WKYMVm 펩타이드, 5-플루오로우라실, 또는 성숙수지상세포를 단독으로 투여하는 것보다, WKYMVm 펩타이드에 5-플루오로우라실 및/또는 성숙수지상세포를 병용투여하면 암의 부피를 약 5배 정도 줄일 수 있다는 것을 확인하였으며(실시예 1 참조), 다른 실시예에서는 병용투여를 통하여 암의 전이를 5배 이상 억제할 수 있다는 것을 확인하였을 뿐만 아니라, 인위적으로 암을 유발시킨 쥐의 생존률을 현저히 증가시킬 수 있다는 것을 확인하였다(실시예 6 및 7 참조).In one embodiment of the present invention, administration of 5-fluorouracil and / or mature dendritic cells in combination with WKYMVm peptide, 5-fluorouracil, or mature dendritic cells alone increases the volume of cancer. It was confirmed that it can be reduced by about 5 times (see Example 1), and in other examples, it was confirmed that the metastasis of cancer can be inhibited by 5 times or more through co-administration. It was confirmed that the survival rate can be significantly increased (see Examples 6 and 7).

상기 결과들로부터, 서열번호 1의 서열을 가지는 WKYMVm 펩타이드를 포함하고, 5-플루오로우라실(5-fluorouracil) 및/또는 성숙수지상세포(mature dendritic cells)를 병용 투여하는 것은 단독으로 사용하는 것보다 항암 효과를 현저히 높일 수 있을 뿐만 아니라, 부작용을 줄이는 동시에 암의 전이까지 억제할 수 있기 때문에, 암의 치료에 적용될 수 있을 것으로 기대된다. 이에 본 발명은 서열번호 1의 서열을 가지는 WKYMVm 펩타이드를 포함하고, 5-플루오로우라실(5-fluorouracil) 및/또는 성숙수지상세포(mature dendritic cells)를 병용투여하여 항암치료 효과를 높이는 방법을 제공한다.From these results, co-administration of 5-fluorouracil and / or mature dendritic cells containing WKYMVm peptide having the sequence of SEQ ID NO. Not only can the anti-cancer effect be significantly increased, but also the side effects can be reduced and cancer metastasis can be suppressed.

Incubated for 5 days in RPMI 1640 medium containing fetal bovine serum, 2 mM L-glutamine, 50 uM beta-mercaptoethanol, and antibiotics, GM-CSF (1,000 U / mL) and IL-4 (500 U / mL) on days 0, 2 and 4. mL) was treated. After 5 days, the cells were collected and transferred to a new DC medium, followed by incubation for 2 days by adding lipopolysaccharide (100ng / mL), CpG oligodeoxynucleotide 1826 (10μg / mL) and CT-26 cell lysate (100μg / mL). Mature dendritic cells were prepared. Subcutaneous injection of CT-26 cell line (5X10 5 cells / 100μL phosphate buffered saline (PBS)), a colon cancer cell line, was induced in 6-8-week-old BALB / c male mice to induce cancer. -3 days). The mice were injected with 100 μg / 100 μL of 5-FU on day 0 (0 day) and day 1 (1 day), respectively, and on day 2, WKYMVm peptide (100 μg / 100 μL) was injected at 12 hour intervals. Four subcutaneous injections and maturated dendritic cells (1 × 10 6 cells / 100 μL) were injected into the tail vein twice at 12 hour intervals. Subsequently, 5-FU (100 μg / 100 μL) was injected subcutaneously at 4 days and 5 days. Thereafter, the mice were repeatedly dosed with WKYMVm peptide, 5-FU, and mature dendritic cells twice a week for 3 weeks. As a control group, mice treated with nothing, WKYMVm peptide, 5-FU, or mature dendritic cells alone or in combination of the two groups were used as mice divided into the experimental group. And the volume of the cancer was quantified using the following formula. A schematic diagram of the experimental procedure is shown in FIG. 1, and the experimental results are shown in FIG. 2.

암의 부피(mm3) = 길이(mm) X 너비(mm)2/2The volume of cancer (mm 3) = length (mm) X width (mm) 2/2

도 2에 나타난 바와 같이, WKYMVm 펩타이드, 5-FU, 또는 성숙수지상세포를 각각 처리한 경우에는 약간 암의 부피가 줄어든 반면, WKYMVm 펩타이드 및 mDC, 또는 mDC 및 5-FU를 병용투여한한 경우에는 암의 부피가 줄어든 것을 확인할 수 있었다. 또한 WKYMVm 펩타이드, 5-FU, 및 성숙수지상세포를 병용투여한 경우에는 암의 부피가 현저하게 줄어든 것을 확인할 수 있었다. 상기 결과를 통하여, 두 개를 병용투여할 경우에도 항암 효과가 증가되지만, 세 개를 모두 병용투여하면 항암효과가 현저히 증가된다는 것을 확인할 수 있었다.

In addition, when the WKYMVm peptide, 5-FU, and mature dendritic cells were administered in combination, it was confirmed that the cancer volume was significantly reduced. Through the above results, the anti-cancer effect was increased even when the two doses in combination, it was confirmed that the anti-cancer effect is significantly increased when all three together.

For morphological analysis, stained with hematoxylin and eosin (H & E) and observed through light microscopy. For immunological analysis, anti-murine cleaved caspase-3 antibody or anti-murine FAS antibody was used. After secondary binding, anti-murine IgG bound to FITC or anti-murine IgG bound to Alexa 594 was used for secondary binding, followed by fluorescence microscopy.

As shown in Figure 3, TUNEL staining, FAS and Caspase-3 staining all showed similar results. When treated with WKYMVm peptide or mature dendritic cells alone, the cells were almost dead, and when treated with 5-FU alone, some of the cells were dead. In addition, even when two were administered in combination, some cells were confirmed to be dead, but in combination with WKYMVm peptide, 5-FU, and mature dendritic cells, almost all of the cells were confirmed to be dead. Through the above results, co-administration of KYMVm peptide, 5-FU, and mature dendritic cells was confirmed to induce apoptosis and kill cancer cells.
