DNMT1 (DNA methyltransferase 1) is a protein-coding gene in humans that is responsible for transferring methyl groups to cytosine nucleotides in DNA. It plays a key role in maintaining methylation patterns after DNA replication, showing a preference for hemimethylated DNA. This methylation process is essential for epigenetic regulation and affects gene expression without changing the DNA sequence itself. This protein is also involved in a variety of molecular functions such as DNA binding and zinc ion binding. It plays a role in many biological processes, including DNA template transcription and cellular response to stimuli. Variations in the DNMT1 gene have been associated with diseases such as cerebellar ataxia, deafness, narcolepsy, and hereditary sensory neuropathy type IE.
DNMT3B (DNA methyltransferase 3 beta) is another protein-coding gene in humans that is essential for the CpG methylation process. Unlike DNMT1, DNMT3B is thought to play a role primarily in de novo methylation. The expression of DNMT3B is developmentally regulated and is primarily located in the nucleus. DNMT3B also plays an important role in other processes, such as transcriptional regulation and cellular responses to environmental factors. Defects or mutations in DNMT3B have been linked to a variety of diseases, including immunodeficiency-centromere instability-facial anomalies (ICF) syndrome, congenital heart defects, and various cancers.
The Human DNMT1/DNMT3B Double Knockout Cell Line - HEK293T is a powerful tool for a variety of research applications in the fields of epigenetics, cancer biology, and gene regulation. Here are some of the key applications:
Epigenetic Research: By eliminating DNMT1 and DNMT3B, researchers can effectively study the effects of disrupted methylation patterns on gene expression, revealing epigenetic regulation of various biological processes.
Cancer Research: Given the role of DNA methylation in cancer, this knockout cell line is valuable for studying the mechanisms by which aberrant methylation leads to carcinogenesis. It helps identify potential biomarkers and therapeutic targets that are unique to epigenetic modifications in cancer cells.
Gene Expression Analysis: Researchers can use high-throughput sequencing and other gene expression analyses to understand the broad effects of DNMT knockout on cellular function, providing insights into gene regulatory networks.
Drug Screening and Development: This cell line is an important model for screening drugs that target DNA methylation pathways. It enables pharmaceutical researchers to identify and evaluate compounds that can modulate methylation, providing potential treatments for diseases associated with epigenetic dysregulation.
Development of Epigenetic Therapies: Using this cell line, researchers can test the efficacy and specificity of new epigenetic therapies. This is particularly important for developing treatments for cancer and other diseases where DNA methylation patterns are disrupted.
A: DMEM supplemented with 10% fetal bovine serum. <br> It is not required to add the selection antibiotics when culturing the KO cells.
A: The knockout cell product is validated by PCR amplification and Sanger Sequencing to confirm the mutation at the genomic level. Please find the detailed mutation info in the datasheet.
A: Single clonal cell.
A: No. This knockout cell product is generated using the CRISPR/Cas9 system to induce small insertions or deletions (indels) resulting in frameshift mutations. Although these frameshift mutations typically disrupt the coding gene, there is a possibility that the non-functional transcript may still be transcribed. Consequently, this could potentially yield misleading results when analyzed by RT-qPCR.
A: The cell line should be stored in liquid nitrogen for long-term preservation.
A: For most cases, we often keep at least 2 clones with different frameshift mutations. Please feel free to contact us to check if there are additional available clones.
