CENPM upregulation by E5 oncoprotein of human papillomavirus promotes radiosensitivity in head and neck squamous cell carcinoma.

Objectives: This study aims to investigate how human papillomavirus (HPV) affects the key gene in the biological behaviors of head and neck squamous cell carcinoma (HNSCC) that leads to better response to radiotherapy.

Materials And Methods: The expression of key gene CENPM was analyzed using The Cancer Genome Atlas (TCGA) HNSCC data and HPV positive and HPV negative HNSCC tumors and cells. Assays with siRNAs, CRISPR/Cas9-based models, Western blot, qRT-PCR, ChIP, etc.

Applications and analytical tools of cell communication based on ligand-receptor interactions at single cell level.

Background: Cellular communication is an essential feature of multicellular organisms. Binding of ligands to their homologous receptors, which activate specific cell signaling pathways, is a basic type of cellular communication and intimately linked to many degeneration processes leading to diseases.

Main Body: This study reviewed the history of ligand-receptor and presents the databases which store ligand-receptor pairs.

Characteristics of B lymphocyte infiltration in HPV head and neck squamous cell carcinoma.

Human papillomavirus (HPV) is an important etiological factor of head and neck squamous cell carcinoma (HNSCC). HPV HNSCC patients usually have a better prognosis, which probably results from the higher infiltration of B lymphocytes. This study was purposed to detect the infiltration of B lymphocyte subsets and the correlation between B lymphocyte subsets and the prognosis in HPV-related HNSCC.

Cellular heterogeneity landscape in laryngeal squamous cell carcinoma.

Laryngeal squamous cell carcinoma (LSCC) is a highly malignant tumor originated from respiratory system. Although there have been many improvements in therapy until now, reducing the high mortality remains difficult. Understanding the cellular heterogeneity of LSCC could contribute to improve this problem.

M2 macrophages reduce the radiosensitivity of head and neck cancer by releasing HB‑EGF.

The aim of the present study was to examine the potential role of human heparin‑binding epidermal growth factor (HB‑EGF) secreted by M2 macrophages in the development of radioresistance in head and neck squamous cell carcinoma (HNSCC). Immunohistochemistry was used to detect radiosensitivity in human papilloma virus (HPV)‑positive and HPV‑negative HNSCC tissues and immunohistochemical staining with specific antibodies for macrophage surface markers was used to assess the infiltration of M1 and M2 macrophages in HPV‑positive and ‑negative HNSCC tissues. The expression of HB‑EGF in HPV‑positive and ‑negative HNSCC tissues was determined by multi‑cytokine detection in order to determine the relationship between HB‑EGF and radiosensitivity.

Ultrasound Elastic Parameters Predict Central Lymph Node Metastasis of Papillary Thyroid Carcinoma.

Background: This study aimed to explore the new factors that can predict central lymph node metastasis (CLNM) of papillary thyroid carcinoma (PTC) independently from ultrasound characteristics, elastic parameters, and endocrine indicators.

Methods: A total of 391 patients with PTC undergoing thyroidectomy and prophylactic central lymph node dissection from January 2017 to June 2019 were collected to determine the independent predictors of CLNM by single-factor and multivariate logistic regression analysis.

Results: Multivariate logistic regression analysis showed 9 independent predictors of CLNM, age, male, tumors in the middle or lower poles (without tumors in the isthmus), tumors in the isthmus, multiple tumors, and maximum tumor diameter measured by ultrasound, microcalcification, visible surrounding blood flow signal, and the maximum value of elastic modulus (Emax).

Genome-wide identification of lncRNAs as novel prognosis biomarkers of glioma.

Background: Glioma is the primary cancer of the central nervous system, and defining the prognosis of glioma is of great significance in the clinical. The long noncoding RNAs (lncRNAs) emerge as important regulators of pathological processes. This study aimed to identify lncRNAs which could function as potential prognosis biomarkers of glioma.

DisV-HPV16, versatile and powerful software to detect HPV in RNA sequencing data.

Background: The increasing availability of high-throughput sequencing data provides researchers with unprecedented opportunities to investigate viral genetic elements in host genomes that contribute to virus-linked cancers. Almost all of the available computational tools for secondary analysis of sequencing data detect viral infection or genome integration events. However, viral oncogenes expression is likely of importance in carcinoma.

Association of lnc-IL17RA-11 with increased radiation sensitivity and improved prognosis of HPV-positive HNSCC.

Human papillomavirus (HPV) associated head and neck squamous cell carcinoma (HNSCC) has a far better prognosis than HPV negative HNSCC. Recent studies suggest that long noncoding RNA (lncRNA) moieties may play a role in HPV associated differential HNSCC prognoses. In this study, we examined differential expression of lncRNAs in HPV vs HPV HNSCC using The Cancer Genome Atlas database.
