히데노리 이노하라 교수의 연구실은 주로 암 생물학과 분자 종양학을 중심으로, 갑상선 및 구강·두경부 암에서의 바이오마커 역할을 하는 galectin-3과 인플루엔자바이러스 감염과 관련된 HPV 감염의 임상적 의미를 탐구하고 있습니다. 특히 HPV 관련 구강암의 진단, 예후 예측 및 치료 반응 평가를 위한 혈액 내 종양 DNA 모니터링 기술 개발에도 주력하고 있습니다. MRI 및 생검 영상 분석과의 융합을 통해 암의 정확한 진단과 생물학적 특성 규명에 기여하고 있습니다.

Galectin-3 is a beta-galactoside-specific lectin implicated in diverse processes involved in cellular interactions. Recently, the Mac-2-binding protein, a heavily N-glycosylated secreted protein with a subunit Mr of 97,000, was identified as its ligand. The present study characterizes the interaction between galectin-3 and Mac-2-binding protein in whole cells and measures their relative expression levels. Incubation of A375 cells with affinity-purified Mac-2-binding protein resulted in its bindi
Galectin-3 serves as a marker of thyroid malignancy of follicular cell origin. Analysis of galectin-3 expression in fine-needle aspirates enhances the differential diagnostic accuracy between benign and malignant thyroid neoplasms.
The clinical significance of human papillomavirus (HPV) in neck node metastasis from cancer of unknown primary (CUP) is not well established. We aimed to address the relationship of HPV status between node metastasis and the primary tumor, and also the relevance of HPV status regarding radiographically detected cystic node metastasis in head and neck squamous cell carcinoma (HNSCC) and CUP. HPV DNA was examined in 68 matched pairs of node metastasis and primary tumor, and in node metastasis from
We aimed to reveal the prevalence and pattern of human papillomavirus (HPV) infection and p53 mutations among Japanese head and neck squamous cell carcinoma (HNSCC) patients in relation to clinicopathological parameters. Human papillomavirus DNA and p53 mutations were examined in 493 HNSCCs and its subset of 283 HNSCCs. Oropharyngeal carcinoma was more frequently HPV-positive than non-oropharyngeal carcinoma (34.4% vs 3.6%, P < 0.001), and HPV16 accounted for 91.1% of HPV-positive tumors. In oro
Positron emission tomography and computed tomography (PET-CT) is widely used to assess the response to radiotherapy. However, the ability of PET-CT to predict treatment failure in human papillomavirus (HPV)-related squamous cell carcinoma of the head and neck (HNSCC) is unsatisfactory. We quantified circulating tumor HPV type16 DNA (ctHPV16DNA) using optimized droplet digital PCR in 35 patients with HPV16-related HNSCC, who received radiotherapy with or without chemotherapy, and prospectively co
Unsharp margin and infiltration into adjacent tissues on MRI significantly correlated with a malignant histology. The sensitivity/specificity/accuracy of FNAC and MRI were 90%/95%/94% and 81%/92%/89%, respectively. Either FNAC or MRI served equally to predict the malignant nature of parotid mass lesions. Furthermore, the combination of FNAC and MRI yielded no diagnostic advantage over either modality alone. Accurate histological typing rates by FNAC were 80% and 62% for benign and malignant lesi
A biomarker that is useful for the detection of human papillomavirus (HPV)-related oropharyngeal cancer (OPC) and cancer of unknown primary (CUP) is indispensable. We evaluated the diagnostic performance of HPV DNA and mRNA in oral gargle samples and circulating tumor HPV16 DNA (ctHPV16DNA) in blood samples. Oral HPV DNA and mRNA were analyzed using commercially available HPV assays of the GENOSEARCH HPV31 and Aptima, respectively. ctHPV16DNA was analyzed using in-house droplet digital polymeras
