Frequent Genetic Alterations and Their Clinical Significance in Patients With Thymic Epithelial Tumors

Frontiers in Oncology, 2021
PurposeThymic epithelial tumors (TETs) are relatively rare neoplasms, including thymomas (types A, AB, B1, B2, and B3) and thymic carcinomas (TCs). The current knowledge about the biological properties of TETs is limited due to their low incidence.

[A patient with lung metastasis of medulloblastoma].

Nihon Kyobu Shikkan Gakkai zasshi, 1996
A 15-year-old boy had metastasis to the spinal cord and then to the lung after an operation to remove a primary medulloblastoma. A medulloblastoma developed at the age of 10 years. The tumor was completely resected and the brain and spinal cord were irradiated.

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Ensartinib as a neoadjuvant therapy for stage IIIA non-small cell lung cancer patients with EML4-ALK fusion: a case report and literature review

Frontiers in Oncology
Anaplastic lymphoma kinase (ALK) inhibitors have shown efficacy in treating ALK-positive advanced non-small cell lung cancer (NSCLC) patients. However, the effectiveness of ensartinib neoadjuvant therapy remains ambiguous.

A Meta-analysis of Association between MGMT Gene 
Promoter Methylation and Non-small Cell Lung Cancer

Chinese Journal of Lung Cancer, 2014
Backgroud and objective DNA promoter methylation of the tumor suppressor genes was one of the key mechanism for gene silence. The aim of this study is to investigate the difference of MGMT gene promoter methylation rate in tumor tissue and autologous ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Mechanism of Warburg Effect and Its Effect on Tumor Metastasis

Chinese Journal of Lung Cancer, 2015
Cancer cells exhibit altered glucose metabolism characterized by a preference for aerobic glycolysis even when the oxygen content is normal, a phenomenon termed “Warburg effect”. However the definite molecular mechanisms of Warburg effect remains unclear,

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Expression and Clinical Significance of PD-1 and PD-L1 in Pulmonary Carcinoids

Chinese Journal of Lung Cancer, 2016
Background and objective The incidence of pulmonary carcinoid (PC) is very rare in primary lung malignant tumors, and the prognosis of this disease is closely associated with its pathological features. In this study, the expressions of programmed death 1
