Objective: To investigate the effect of FAK on biological characteristics of tongue squamous cell carcinoma cell Tca8113.
Methods: Lipofect was used to transfect FAK into Tca8113 cell lines. The difference in expression of FAK between the transfected and non-transfected cell lines was detected by immunofluorescence assay. Then by use of transwell room and wash way, the difference in invasion and adhesion ability between the transfected and non-transfected cell lines was tested. MTT method was adopted in finding the change of proliferation.
Results: RT-PCR analysis showed that the FAK gene was downregulated by Tca8113 cells. FAK expression was significantly down regulated by the transfection of FAK ASODN (P<0.05). Antisense FAK ODN significantly inhibited proliferation, adhesion and the invasion of Tca8113 cells.
Conclusion: FAK plays an important role on biological characteristics of tongue squamous cell carcinoma cell Tca8113.

Background: A precise observation is that the cervix's solid tumors possess hypoxic regions where the oxygen concentration drops below 1.5%. Hypoxia negatively impacts the host's immune system and significantly diminishes the effectiveness of several treatments, including radiotherapy and chemotherapy.

Diabetic retinopathy (DR) is a blinding complication of microangiopathy. First-line therapeutic drugs are all focused on late-stage DR and have several side effects, which could not meet clinical needs. The plant-derived ginsenoside Ro (Ro) has a variety of effective anti-inflammatory, immune-regulating, and cardiovascular protective effects, but its microvascular protective effects are rarely studied.

This study aimed to investigate the underlying mechanisms by which physical exercise mitigates muscle atrophy induced by Dexamethasone (Dex). A muscle atrophy model was established in the mouse C2C12 cell line and 8-week-old mice treated with Dex, with subsequent verification of phenotype and atrogene expression. The potential benefits of combined aerobic and resistance exercise in mitigating muscle atrophy were then examined.

Neuroblastoma (NB) is the most common extracranial solid tumor in children, with variable outcomes ranging from spontaneous remission to high-risk cases often leading to relapse or refractory disease. Approximately 50% of patients with NB have high-risk features, often experiencing relapse or refractory disease despite intensive treatments and the prognosis remains poor, with long-term event-free survival (EFS) rates below 10%,Radioactive iodine-labeled meta-iodobenzylguanidine (¹³¹I-mIBG) therapy, leveraging NB cells' radiosensitivity and expression of the norepinephrine transporter (NET), has shown promise in treating relapsed or refractory NB. Since 1985, ¹³¹I-mIBG has been studied to determine the maximum tolerated dose and side effects, with recent trials exploring its use in front-line treatment.
