Abstract

Astrocytoma represents most noted malignancy of the brain. The overall survival rate of patients with progressive form remains dismal despite of the present clinical advancements. Search for biomarkers can open new avenues of therapeutic measures to curb the progressive astrocytic tumors. Nck1 is reported to be involved in actin cytoskeleton rearrangement and neuronal migration. Here, we have determined prognostic importance of Nck1 protein in astrocytoma progression. Temporal lobe epilepsy tissues were used as control. Real time PCR was used to analyze Nck1 transcript expression while western blotting and immunohistochemistry techniques were used to study expression on translational levels. Protein expression in western blots was categorized as Nck1 positive and Nck1 negative. We further seen the prognostic significance of Nck1 in 246 glioblastoma tissue samples as visible from the TCGA database. We find Nck1 RNA and protein was upregulated significantly in high grade tissues as compared to low grade and control tissue samples (p < 0.05). Logrank test and Kaplan-Meier analysis signified the use of Nck1 as independent prognostic marker for astrocytoma progression and its expression levels were correlated with poor survival in s...Continue Reading

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
