SK-N-SH Cell Line:
Pediatric brain tumors are considered the leading cause of cancer-related deaths in children, despite new brain cancer treatments and therapies that are implemented every year. The vast majority of brain cancers are highly invasive and predict poor prognosis; therefore, innovative immunotherapy treatment options are desperately needed. Established cell lines are valuable preclinical models for brain cancer research that provide scientists with a better understanding of the biology of the disease and could lead to the development of brain cancer therapeutics. The SK-N-SH cell line was isolated by J.L. Biedler in 1970 from brain tissue of a 4-year-old female patient during a bone marrow biopsy of a metastatic neuroblastoma. SK-N-SH cells make for a good transfection host and show a higher doubling time as well as higher levels of dopamine-beta-hydroxylase production. The modal chromosome number of this cell line is 47. SH-SY5Y is a triple-cloned neuroblastoma, which originated in 1978 from the SK-N-SH line. A neuroblast-like subclone of SK-N-SH was named SH-SY. The SH-SY cell line was subcloned as SH-SY5 and was subcloned one more time as SH-SY5Y. This cell line is genetically female, with two X chromosomes. SH-SY5Y possess an abnormal chromosome called trisomy 1q. The cell line has been shown to be acetylcholinergic, glutamatergic and adenosinergic as well as dopamine beta-hydroxylase active. SH-SY5Y propagate through mitosis and differentiate by extending neurites to the surrounding area. The cells can form clusters of cells that remind of their malignant nature. However, different treatments, including retinoic acid and brain-derived neurotrophic factor, can make the cells to dendrify and differentiate. It has been shown that citrus limonoid glucosides can be toxic to SH-SY5Y cancer cells. The SK-N-SH neuroblastoma cell line exhibits neurite outgrowths through modulated differentiation, which makes these cells very useful in the study of neural pathways. Altogen Biosystems provides lipid-based transfection kits for the SK-N-SH cell line.
Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into SKNSH cells following the recommended protocol. At 48 hours post-transfection the cells were analyzed by qRT-PCR for Lamin A/C gene expression levels. 18S rRNA levels were used to normalize the Lamin A/C data. Values are normalized to untreated sample. Data are means ± SD (n=4).
Figure 2. Protein expression of Lamin A in SK-N-SH cells. DNA plasmid expressing Lamin A or siRNA targeting Lamin A were transfected into SK-N-SH cells following Altogen Biosystems transfection protocol. At 72 hours post-transfection the cells were analyzed by Western Blot for protein expression levels (normalized by total protein, 10 µg of total protein loaded per each well). Untreated cells used as a negative control.
