UV light excites aromatic residues, causing these to disrupt nearby disulphide bridges. The EGF receptor is rich in aromatic residues near the disulphide bridges. Herein we show that laser-pulsed UV illumination of two different skin-derived cancer cell lines i.e. Cal-39 and A431, which both overexpress the EGF receptor, leads to arrest of the EGFR signaling pathway. The phosphorylation status ...
The molecular mechanism formation of secondary epiretinal membranes (ERMs) after proliferative diabetic retinopathy (PDR) or primary idiopathic ERMs is still poorly understood. Therefore, the present study focused on the assessment of IGF1, IGF1R, and IGFBP3 mRNA levels in ERMs and PBMCs from patients with PDR. The examined group comprised 6 patients with secondary ERMs after PDR and the contro...
Cell cultures were established from 8 lymph nodes replaced by nodular sclerosing Hodgkin's disease. Serum-containing and serum-free conditioned media from these cultures potentiated fibroblast growth and were found to be consistently more potent than fibroblast growth factor, 100 ng/ml, every other day. Both a proliferative response and transformation-like growth were observed using BALB/c 3T3 ...
Oral Squamous cell carcinoma (OSCC) accounts for over 90% of oral cancer cases and a small percentage of these cases are thought to develop from potentially malignant disorders. Main etiological factor associated with OSCC is smoking. It’s a well known fact that in chronic smokers nuclear alterations are evident. There is a correlation between nucleolar function, size and cell doubling time in ...
Pathological lesions of parathyroid glands encompass a wide range of lesions ranging from developmental anomalies to inflammatory disorders to neoplastic processes. Proliferative lesions of parathyroid glands represent the commonest causes of hyperparathyroidism in clinical practice. However, the parathyroid specimens represent only a tiny fraction of the workload received in a non-specialist h...
The biliary system plays an important role in several acquired and genetic disorders of the liver. We have previously shown that biliary duct epithelium contains cells giving rise to proliferative Lgr5+ organoids in vitro. However, it remained unknown whether all biliary cells or only a specific subset had this clonogenic activity. The cell surface protease ST14 was identified as a positive mar...
