The present invention relates to a kit for detecting HPV including a primer, and (b) a probe capable of identifying the amplified product, a method of detecting HPV using the same, and a method of diagnosing HPV infection.
HPV (human papiilomavirus, 인유두종 바이러스)는 가장 흔하게 성적으로 전파되는 감염성 질환을 일으키는 바이러스 중의 하나이다. 또한 HPV는 피부 사마귀(wart) 등의 양성 질환부터 자궁경부암까지 다양한 질병을 일으킨다. 전세계적으로 자궁경부암은 여성 암의 15%를 차지하고, 우리나라의 경우에서도 여성에게 발생하는 암 중 6번째로 10.6%의 아직 높은 발생빈도를 보이고 있으며 그로 인한 사망률은 60%에 이른다. HPV (human papillomavirus) is one of the most commonly transmitted sexually transmitted infectious diseases. In addition, HPV causes a variety of diseases, from benign diseases such as skin warts to cervical cancer. Cervical cancer worldwide accounts for 15% of female cancers, and in Korea, it is the 6th among female cancers, still showing a high incidence of 10.6%, and the resulting mortality rate reaches 60%.
HPV는 조직 배양법이나, 실험 동물에서 자라게 할 수가 없으나, 최근에는 분자 생물학적 방법으로 PCR법을 이용하여 HPV의 여러 아형을 구분하여 확인할 수 있다. PCR법은 빠르고 민감도가 높아 미량의 HPV도 검출해낼 수 있으나 전기영동 과정을 거쳐야 하기 때문에 안전성과 신속성에서 문제를 보여주고 있다. 그 대안으로 현재 가장 활발히 개발되고 있는 real-time PCR은 고가의 장비가 필요해 경제성이 떨어지는 단점이 있다. HPV cannot be grown in tissue culture or experimental animals, but recently, it is possible to identify and identify various subtypes of HPV using PCR as a molecular biological method. The PCR method is fast and highly sensitive, so it can detect even trace amounts of HPV, but it has to go through an electrophoresis process, showing problems in safety and speed. As an alternative, real-time PCR, which is currently most actively developed, requires expensive equipment, which has a disadvantage of low economic efficiency.
전 세계적으로 자궁경부암을 일으키는 HPV의 감염률은 11.4%에 이르며, 주요 발병인자는 HPV로, 현재까지 118종의 HPVs가 알려져 있고, 이 중에서 약 10여종이 암을 유발하는 고위험 유전형으로 분류되고, 현재까지 이러한 고위험 유전형 HPV의 지속감염이 가장 큰 위험요인으로 알려져 있다.Worldwide, the infection rate of HPV, which causes cervical cancer, reaches 11.4%, and the main pathogen is HPV, and 118 types of HPVs are known to date, of which about 10 are classified as high-risk genotypes that cause cancer. Until now, persistent infection of the high-risk genotype HPV is known as the greatest risk factor.
자궁경부암 선별검사로 가장 널리 쓰이고 있는 Pap smear 검사는 저렴하고 효과적인 방법으로 자궁경부암의 유병률과 사망률의 감소에 지대한 공헌을 하였다. 그러나, Pap smear 검사는 자체 제한성으로 인해 피할 수 없는 위음성률을 지니고 있으며, 또한 암 발생의 가장 중요한 요인인 HPV 감염 여부를 진단하지 못하는 맹점이 있다.The Pap smear test, which is widely used as a screening test for cervical cancer, is an inexpensive and effective method that has greatly contributed to the reduction of the prevalence and mortality of cervical cancer. However, the Pap smear test has an unavoidable false negative rate due to its own limitations, and also has a blind spot in which it cannot diagnose HPV infection, which is the most important factor in the occurrence of cancer.
Pap smear와 HPV 유전형 검사를 동시에 실시했을 때, 자궁경부암 발견 예측도가 Pap smear 검사나 HPV 유전형 검사를 단독으로 하였을 때 보다 높게 나타나는 연구 결과로 인해 HPV 검사의 중요성이 인식되었다. When Pap smear and HPV genotyping were performed at the same time, the importance of HPV test was recognized due to the results of the study showing that the predictive value of cervical cancer detection was higher than that of Pap smear or HPV genotyping alone.
핵산증폭기술을 이용한 인유두종 바이러스 감염 여부에 대한 진단 검사는 현재 로슈(Roche)사와 퀴아젠(QIAGEN)사 등이 제공하고 있으며, 국내 기업으로는 국내 업체 중 ㈜바이오니아, ㈜파나진, ㈜씨젠 등이 제공하고 있다. Diagnosis tests for human papillomavirus infection using nucleic acid amplification technology are currently provided by Roche and QIAGEN, and as domestic companies, Bioneer Co., Ltd., Panazine Co., and Seegene Co., Ltd. are provided among domestic companies. Are doing.
다만, 검사에 사용되는 키트는 형광물질을 사용하여 가격도 고가이고 온도조절을 위한 고가의 반응설비와 분석을 위한 고가의 형광검출기를 필요로 하여 사용이 보편화되기에는 커다란 경제적 제약이 있다. real-time PCR법은 고가의 장비가 필요하여 경제성이 크게 떨어지고 있어 국민보건향상에 커다란 걸림돌이 되고 있는 실정이다.However, since the kit used for the test uses a fluorescent material, it is expensive, and requires an expensive reaction facility for temperature control and an expensive fluorescence detector for analysis, so there is a great economic limitation for its use. The real-time PCR method requires expensive equipment, and the economic feasibility is greatly reduced, which is a big obstacle to improving public health.
이러한 기술적 배경하에서, 본 출원의 발명자들은 고위험 유전형 HPV 특이적 유전자를 검출함으로써 신속 정확하게 정성적으로 HPV의 감염 여부를 진단할 수 있고, 미량의 검체 유전자만으로 HPV 감염 여부에 대한 진단이 가능한 키트, 이의 검출방법 및 이를 이용한 HPV 감염 여부에 대한 진단방법을 제공할 수 있음을 확인하고, 본 발명을 완성하였다.

분자진단 제품 중 중합효소 연쇄 반응기법(Polymerase Chain Reaction, PCR) 이용하는 제품은 크게 두 가지로 분류할 수 있다. 하나는 종래 PCR로, 검체로부터 핵산을 추출하여 표적핵산을 증폭한 후 전기영동을 통해 그 결과를 확인한다. 이 방법을 사용하게 되면 저렴한 가격의 키트를 구입할 수 있지만 전기영동에 많은 노동력과 시간이 소요된다. 전기영동을 대신하여 사용하는 리얼-타임 PCR (Real-time PCR) 기법은 병원균의 핵산 증폭을 실시간으로 모니터링 할 수 있지만 키트의 가격이 고가이다. Among the molecular diagnostic products, products that use polymerase chain reaction (PCR) can be classified into two broad categories. One is conventional PCR, which extracts a nucleic acid from a sample, amplifies the target nucleic acid, and then confirms the result through electrophoresis. Using this method, you can buy a kit at an inexpensive price, but electrophoresis takes a lot of labor and time. Real-time PCR, which is used instead of electrophoresis, can monitor the amplification of nucleic acids of pathogens in real time, but the cost of the kit is expensive.

Accordingly, while maintaining user convenience, as the development of inexpensive molecular diagnostic products is required, the inventors of the present application have developed an in vitro diagnostic kit for qualitative analysis.

1. 키트의 제작1. Making the kit
본 발명에 따른 키트 (이하, PaxView HPV 20 Genotyping MPCR-ULFA Kit로도 명명)는 두 개의 키트를 포함한다. 하나는 핵산을 증폭하는 키트 (이하, Component 1. PaxView HPV 20 Genotyping MPCR Kit)이고, 다른 하나는 증폭산물을 확인하는 키트 (이하, Component 2. PaxView HPV 20 Genotyping MPCR Kit)이다. PaxView HPV 20 Genotyping MPCR-ULFA Kit의 구성품인 프라이머 혼합물에 포함된 프라이머는 표 1에 따른 2개의 패널에 구성된 20가지 타입의 HPV에 대한 부위와 내부 대조에 대한 부위 외에, 정방향 프라이머 (Forward primer=SN)에는 비상보적 핵산 올리고머인 유니버셜 부위 (universal region)가, 역방향 프라이머 (Reverse primer=ASN)에는 비오틴 서열이 태깅 (tagging)되어 있다 (도 1). The kit according to the present invention (hereinafter, also referred to as PaxView HPV 20 Genotyping MPCR-ULFA Kit) includes two kits. One is a kit for amplifying nucleic acids (hereinafter, Component 1. PaxView HPV 20 Genotyping MPCR Kit), and the other is a kit (hereinafter, Component 2. PaxView HPV 20 Genotyping MPCR Kit) that identifies amplification products. The primers included in the primer mixture, which is a component of the PaxView HPV 20 Genotyping MPCR-ULFA Kit, is a forward primer (Forward primer = SN) in addition to the site for 20 types of HPV and the site for internal control composed of two panels according to Table 1. ) Is a universal region, which is a non-complementary nucleic acid oligomer, and a biotin sequence is tagged to a reverse primer (ASN) (Fig. 1).

PCR 후 증폭산물을 PaxView ULFA Kit의 ULFA 디바이스에 로딩하면 골드-스트렙타비딘 접합체 (Gold-streptavidin conjugate=Gold-SV, 글라스 파이버 (Glass fiber) 소재의 패드 (pad)에 존재)와 결합 후 NC (nitrocellulose) 멤브레인 위에 흡착되어 있는 프로브 (probe = 유니버셜 부위 (universal region)에 상보적인 올리고)와 결합하여 각 병원균의 표시 부위에서 발색한다. 발색 원리는 각 프라이머에 태깅된 비오틴과 스트렙타비딘의 반응법에 의한 것으로 많이 사용되고 있는 항원-항 체 반응 외에 DNA 반응 확인에도 활용할 수 있다. 아비딘과 유사한 스트렙타비딘은 비오틴과 복합체를 형성할 수 있어 비오틴에 접합된 골드 입자 (gold particle)에 의해 육안으로 판독 가능한 발색이 일어난다 (도 2). After PCR, the amplification product is loaded into the ULFA device of the PaxView ULFA Kit, and after binding with the gold-streptavidin conjugate (Gold-streptavidin conjugate=Gold-SV, present on the glass fiber pad), NC ( nitrocellulose), a probe adsorbed on the membrane (probe = oligo complementary to the universal region) is combined to develop color at the labeled site of each pathogen. The principle of color development is based on the reaction method between biotin and streptavidin tagged to each primer, and can be used to confirm DNA reactions in addition to antigen-antibody reactions, which are widely used. Streptavidin, similar to avidin, can form a complex with biotin, resulting in a visually readable color development by gold particles conjugated to biotin (FIG. 2).
발색 후 ULFA 디바이스를 육안으로 판독한다. 키트의 사용방법에 기재된 결과 판정에 따라 음·양성을 판정하며 HPV의 타입에 따라 발색선의 위치가 달라지므로 예상 밴드 패턴과 실제 밴드 패턴이 일치함을 확인할 수 있다 (도 4). After color development, the ULFA device is visually read. It can be confirmed that the predicted band pattern and the actual band pattern are identical because the position of the color line is different according to the result determination described in the method of use of the kit.
