HT-29 Cell Line:
According to the Colon Cancer Alliance (CCA), the incidence rates for colon cancer are on the rise in patients younger than age 50, and new treatment regimens are desperately needed. The tumorigenic HT-29 colon cancer cell line is an important tool for the synthesis and investigation of novel cancer drugs. HT-29 was derived in 1964 from the tumor of a 44-year-old woman with colon adenocarcinoma. HT29 cells are human intestinal epithelial cells, which produce the secretory component of Immunoglobulin A (IgA) and carcinoembryonic antigen (CEA). The HT-29 line is designated heterotransplantable, forming well-differentiated grade I tumors. The structure of HT-29 cells include microvilli, microfilaments, mitochondria, smooth and rough endoplasmic reticulum with free ribosomes, lipid droplets, limited primary lysosomes and many secondary lysosomes. The cells express urokinase receptors but do not have detectable plasminogen activator activity. HT-29 cells have been shown to be negative for CD4, but there is expression of galactose ceramide. HT-29 cells are commonly employed for tumorigenicity studies. Also, the HT-29 cell line is extensively used as model system to study epithelial differentiation in vitro. The HT-29 cell line a suitable host for gastric cancer research as well as for studying human infections related to the stomach. Altogen Biosystems offers nanoparticle-based transfection reagent kits that have shown low cytotoxicity for the HT-29 cell line.
Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into HT-29 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/C in HT-29 cells. DNA plasmid expressing Lamin A/C or siRNA targeting Lamin A/C were transfected into HT-29 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.

Altogen Biosystems provides preoptimized transfection products for life science research applications. Transfection protocols are optimized for individual cancer cell lines. Altogen Biosystems developed two types of in vivo delivery kits for animal research: Tissue-targeted reagents (delivery to liver, pancreas, and kidney tissues), and broad range in vivo delivery reagents (PEG-Liposome, Nanoparticle-based, Lipid-based, and Polymer-based kits). Advanced formulation of reagents and optimized transfection protocols provide efficient intracellular delivery of proteins, DNA, RNA, and any other negatively charged molecules in vitro and in vivo.
