Thyroid Res . 2024 Sep; 17(1):21. PMID: 39278941
Introduction: Activation of the MAPK pathway by genetic mutations (such as BRAF and RET) initiates and accelerates the growth of papillary thyroid carcinoma (PTC). However, the correlation between genetic mutations...

Kitagawa Y, Kondo S, Fukuyo M, Wakae K, Dochi H, Mizokami H, et al.
Cancer Sci . 2024 Aug; 115(11):3587-3595. PMID: 39196700
Cancer cells show a dynamic metabolic landscape, requiring a sufficient supply of nucleotides to proliferate. They are highly dependent on de novo purine biosynthetic pathways for their nucleotide requirements. Phosphoribosyl...

Int J Cancer . 2023 Nov; 154(5):895-911. PMID: 37907830
Epstein-Barr virus (EBV)-associated nasopharyngeal carcinoma (NPC) cells have high metastatic potential. Recent research has revealed that the interaction of between tumor cells and the surrounding stroma plays an important role...

Kobayashi E, Kondo S, Dochi H, Moriyama-Kita M, Hirai N, Komori T, et al.
Cancers (Basel) . 2022 Jun; 14(12). PMID: 35740492
Nasopharyngeal carcinoma (NPC) is one of the Epstein-Barr virus (EBV)-associated malignancies. NPC is highly metastatic compared to other head and neck carcinomas, and evidence has shown that the metastatic features...

Cancer Sci . 2022 May; 113(8):2862-2877. PMID: 35633182
Several epidemiological studies have suggested that Epstein-Barr virus (EBV) lytic infection is essential for the development of nasopharyngeal carcinoma (NPC), as the elevation of antibody titers against EBV lytic proteins...

Microorganisms . 2021 Apr; 9(3). PMID: 33804064
Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus (EBV)-associated malignancy. The principal oncogene of EBV, latent membrane protein 1 (LMP1), induces the expression of programmed death-ligand 1 (PD-L1), which is an...
