Western blot - Human MGMT knockout HCT116 cell line (AB286541)

Western blot : Anti-MGMT antibody [MT3.1] (ab39253) staining at 1/500 dilution, shown in green; Rabbit anti-alpha Tubulin antibody [EP1332Y] (ab52866) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab39253 was shown to bind specifically to MGMT. A band was observed at 22 kDa in wild-type HCT 116 cell lysates with no signal observed at this size in MGMT knockout cell line ab286541. The band observed in the knockout lysate lane below 22 kDa is likely to represent a truncated form of MGMT. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and MGMT knockout HCT 116 cell lysates were analysed.First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L 800CW and Goat anti-Rabbit IgG H&L 680RD at 1/20000 dilution.

Product details

Although we aim to provide customers with a homozygous clone, feasibility will be dependent on the biology of the protein. Should only heterozygous edits be achieved, you will be notified of the outcome and be asked to confirm whether the cell line is acceptable. All clones will be accompanied with DNA sequencing data, and the mutation description.

Recommended control: Human wild-type HCT116 cell line (ab288559). Please note a wild-type cell line is not automatically included with a knockout cell line order, if required please add recommended wild-type cell line at no additional cost using the code WILDTYPE-TMTK1.

We will provide viable cells that proliferate on revival.

Handling procedures

Initial handling guidelines

Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.

1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.

Subculture guidelines
  • All seeding densities should be based on cell counts gained by established methods.
  • A guide seeding density of 2x104 cells/cm2 is recommended.
  • Cells should be passaged when they have achieved 80-90% confluence.

Supplementary information

MGMT also known as O-6-methylguanine-DNA methyltransferase is an enzyme with a significant role in DNA repair. MGMT protein has a molecular weight of about 22 kDa. This protein is typically expressed in various tissues including the liver kidney and brain where it functions to protect cells from mutagenic and cytotoxic alterations. MGMT works by transferring alkyl groups from the O6 position of guanine to a cysteine residue within its active site. This mechanism directly reverses DNA damage maintaining genomic stability.
Biological function summary

MGMT prevents mutations by reversing alkylation damage playing a significant role in preserving DNA integrity. It acts independently and does not form part of any larger protein complexes. This enzyme-mediated repair is central to cellular defense against mutagenic threats such as alkylating agents. By curbing DNA damage MGMT can thwart the onset of harmful genetic mutations that might lead to issues like cancer development.

Pathways

MGMT is intimately involved in DNA damage response and repair pathways. Notably it interacts with base excision repair and direct reversal repair pathways. MGMT's function is distinct but complementary to the activities of other DNA repair proteins like XRCC1 and APE1 which are involved in the base excision repair pathway. The presence of MGMT bolsters cellular resilience by ensuring that DNA lesions caused by alkylating agents are addressed promptly and effectively.

MGMT has a profound association with several types of cancer such as glioblastoma and colorectal cancer. Reduced MGMT expression or activity can lead to enhanced susceptibility to the carcinogenic effects of alkylating agents making cancer development more likely. Additionally MGMT inhibitors such as lomeguatrib are used therapeutically to enhance the effectiveness of alkylating chemotherapy. Within this context MGMT interacts with proteins involved in tumor suppression and cell cycle regulation including p53 influencing both cancer progression and treatment outcomes.
