CDK6 is a novel predictive and prognosis biomarker correlated with immune infiltrates in multiple human neoplasms, including small cell lung carcinoma.

The roles of cyclin-dependent kinase 6 (CDK6) in various cancers, including small cell lung carcinoma (SCLC), remain unclear. Here, 111,54 multi-center samples were investigated to determine the expression, clinical significance, and underlying mechanisms of CDK6 in 34 cancers. The area under the curve (AUC), Cox regression analysis, and the Kaplan-Meier curves were used to explore the clinical value of CDK6 in cancers.

ITGB4 Serves as an Identification and Prognosis Marker Associated with Immune Infiltration in Small Cell Lung Carcinoma.

Integrin beta 4 (ITGB4) is a vital factor for numerous cancers. However, no reports regarding ITGB4 in small cell lung carcinoma (SCLC) have been found in the existing literature. This study systematically investigated the expression and clinical value of ITGB4 in SCLC using multi-center and large-sample (n = 963) data.

In the present study, we used 7,12-dimethylbenz(alpha)anthracene to induce orthotopic tongue carcinogenesis in hamsters.

HLA-DRA/HLA-DRB5 polymorphism affects risk of sporadic ALS and survival in a southwest Chinese cohort.

Introduction: Frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD) are neurodegenerative diseases that share common genetic risk factors. A recent genome-wide association study has linked risk of FTD with polymorphisms in the HLA-DRA/HLA-DRB5 gene (rs9268877, rs9268856), BTNL2 gene (rs1980493), and RAB38/CTSC gene (rs302668).

Methods: We used the SNPscan™ Kit to genotype these variants in 400 Chinese patients with sporadic ALS, 554 with sporadic PD and 634 healthy controls.

Comparative morphological study on the lingual papillae and their connective tissue cores in rabbits.

The morphological structure of the lingual papillae and their connective tissue cores (CTC) in a rabbit were studied using LM and SEM and were compared to that of other animal species. Externally, the filiform papillae distributed on the anterior surface of the dorsal tongue were short and conical with a round base and had a flat area on their anterior upper half. The CTC of the conical filiform papillae had a roughly triangular plate-like structure with a round top.

Comparative morphological study on the lingual papillae and their connective tissue cores (CTC) in reeves' muntjac deer (Muntiacus reevesi).
