The ATM gene, also known as ATM serine/threonine kinase, plays a vital role in maintaining cellular health. It is located on chromosome 11 and provides instructions for the production of the ATM protein, which is primarily located in the cell nucleus. One of the main functions of the ATM protein is to help cells recognize and repair damaged or broken DNA strands. DNA damage can occur due to a variety of factors, such as toxic chemicals, radiation, or natural events when chromosomes exchange genetic material during cell division. The ATM protein coordinates the DNA repair process by activating enzymes that repair broken DNA strands, thereby maintaining the stability of the cell's genetic information. This is essential for preventing mutations and ensuring normal cellular functioning. Mutations in the ATM gene can lead to a range of health problems, most notably Ataxia-Telangiectasia (A-T). This rare genetic disorder is characterized by difficulty coordinating movements (ataxia) that gradually develops starting in early childhood. Individuals with A-T have mutations in both copies of the ATM gene, resulting in the production of abnormally small and nonfunctional ATM proteins. As a result, cells are highly sensitive to radiation and fail to respond adequately to DNA damage, leading to the accumulation of mutations and potentially the development of cancerous tumors. In addition, carrying a single mutated copy of the ATM gene increases the risk of developing a variety of cancers, including breast, stomach, bladder, pancreatic, lung, and ovarian cancers.
Applications of Human ATM Knockout Cell Line - HeLa: 1. Cancer Research: The ATM (Ataxia Telangiectasia Mutated) gene plays a crucial role in the cellular response to DNA damage. Knockout HeLa cells lacking functional ATM are used to study the mechanisms of cancer development and progression, particularly regarding how cells respond to DNA damage and how carcinogenesis proceeds when such repair pathways are impaired. 2. Drug Testing and Development: This cell line aids in screening potential anti-cancer drugs. By understanding how ATM deficiency affects the sensitivity of cells to various compounds, researchers can identify and develop targeted therapies that are more effective against tumors carrying similar genetic defects. 3. Cell Cycle Regulation Studies: ATM is involved in cell cycle checkpoints, particularly after DNA damage. Studying ATM-deficient HeLa cells allows scientists to unravel the complexity of cell cycle regulation. 4. Signaling Pathway Analysis: ATM is a key player in various signaling pathways. Knockout cell lines allow exploration of the dynamics of these pathways, providing deeper insights into how cells transmit stress signals, repair damage or initiate apoptosis, thus broadening the understanding of cellular responses to various stimuli.
Customer Q&As
What is the recommended growth medium? Does it require antibiotic selection?

A: DMEM supplemented with 10% fetal bovine serum.
It is not required to add the selection antibiotics when culturing the KO cells.

How is the knockout cell line validated?

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.

Is the product a single clonal cell or mixed cell pool?

A: Single clonal cell.

Can I confirm gene knockout by RT-qPCR?

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.

How can I store the cell product?

A: The cell line should be stored in liquid nitrogen for long-term preservation.

Is it possible to get multiple knockout clones for my GOI?

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.
