Objective: To investigate the inhibition of hTERT gene to Hep-2 cells of laryngeal neoplasms.

Method: siRNA-hTERT mRNA was designed. Hep-2 cells, cultured in vitro, were transfected with lipofectamine 2000 and the inhibitory effect was detected by reverse transcriptase (RT-PCR), MTT assay, and morphology.

Result: 1. siRNA were transfected into Hep-2 cells successfully; 2. RT-PCR showed the exogenous hTERT was knocked down 70% by siRNA; 3. The morphology and the MTT result showed the hTERT siRNA to be able effectively to suppress the Hep-2 cell multiplication, the suppression rate achieves 65%.

Conclusion: siRNA target to hTERT can remarkably suppress the proliferation of Hep-2 cell.

serotype 2 ( type 2, SS2) is one of the zoonotic pathogens known to induce meningitis, septicemia, and arthritis in both pigs and humans, resulting in public health concerns. CbpD, also termed CrfP, is one of the choline-binding proteins (CBPs) that was found as a murein hydrolase in SS2 and plays crucial roles in natural genetic transformation under the control of ComRS-ComX regulatory system by a previous study. Nonetheless, the possible functions of CbpD in virulence and pathogenesis in SS2 remain unclear.

Interaction of Human Respiratory Syncytial Virus (HRSV) Matrix Protein with Resveratrol Shows Antiviral Effect.

The respiratory syncytial virus (RSV) matrix protein plays key roles in the virus life cycle and is essential for budding, as it stimulates the optimal membrane curvature necessary for the emergence of viral particles. Resveratrol, a polyphenol (3,4',5-trihydroxy-trans-stilbene) produced by plants, exhibits pharmacological effects, including anti-inflammatory and antiviral activities. In this study, resveratrol was tested in HEp-2 (Epidermoid carcinoma of the larynx cell) cells for its post-infection effects, and recombinant M protein was produced to characterize the biophysical mechanisms underlying this interaction.

Background: Head and neck squamous cell carcinomas are the seventh most common cancer accounting for 90 % of malignant neoplasia of the upper respiratory system. KRAS is a very important oncogene, leading to the suppression of apoptosis, and promoting the pathogenesis and development of tumors. MicroRNAs (miRNAs) are highly conserved, small noncoding RNA molecules aberrantly expressed in various pathologies including regulation of tumor and metastasis-associated genes.

The Anti-Nuclear Antibodies (ANA) test using Human Epithelial type 2 (HEp-2) cells in the Indirect Immuno-Fluorescence (IIF) assay protocol is considered the gold standard for detecting Connective Tissue Diseases. Computer-assisted systems for HEp-2 image analysis represent a growing field that harnesses the potential offered by novel machine learning techniques to address the classification of HEp-2 images and ANA patterns. In this study, we introduce an innovative platform based on transfer learning with pre-trained deep learning models.

Anti-nuclear mitotic apparatus (NuMA) 1 antibodies are uncommonly detected in routine antinuclear antibody (ANA) screening. We present the case of a 65-year-old female with rheumatoid arthritis undergoing golimumab biotherapy who developed lupus-like symptoms including photosensitivity, fatigue, weakness, myalgias, alopecia, oral ulcers, and worsening of arthritis. Elevated serum levels of NuMA-1 antibodies were detected using indirect immunofluorescence (IIF) on HEp-2 cells with a titer of 1:1000, but no other ANA patterns were associated.
