Is there a cure for cancer?

MIT researchers have developed a novel technique using prime editing, a variant of CRISPR genome-editing, to screen thousands of mutations in cancer genes, such as the tumor suppressor gene p53, more efficiently. This method allows for the identification of harmful mutations previously overlooked, shedding light on their role in tumor development and response to treatment. Unlike previous approaches, which introduced artificial versions of mutant genes, this technique edits the genome directly, providing more accurate insights into mutation effects.

The researchers demonstrated the effectiveness of their approach by examining over 1,000 mutations in the p53 gene found in cancer patients, revealing previously unknown harmful mutations. By enabling the generation of various mutations seen in cancer patients and testing their response to therapy, this technique holds promise for precision medicine, potentially revolutionizing cancer treatment strategies. With further exploration into other cancer-linked genes, the researchers aim to uncover new therapeutic targets and eventually personalize cancer therapies based on individual genetic makeup, marking a significant advancement in cancer research and treatment.

In AP Bio’s Unit 6 on Cell Cycle and Mendelian Genetics, we briefly touched upon the topic of cancer, but I found myself captivated and eager to delve further into its complexities and implications. In learning about cancer, I discovered that its development stems from cells breaking free of normal controls, leading to unregulated division and tumor formation. Unlike normal cells, cancer cells disregard signals that regulate division, perpetuating their growth indefinitely. Furthermore, cancer spreads through a process called metastasis, where tumors manipulate blood vessels to obtain nutrients and travel to distant parts of the body, contributing significantly to cancer-related deaths. Treatments target the diverse population of cancer cells, aiming to eliminate them; however, the high mutation rate often leads to drug resistance and tumor recurrence.

Growing up, I heard stories of my family’s experiences with cancer, especially the loss of my mother’s birth father to a rare liver cancer when she was just a child. His passing at such a young age left an indelible mark on our family. Unfortunately, his story isn’t the only one. Cancer has touched other members of my family too, reminding me of the importance of understanding this disease. Instead of feeling weighed down by sadness, I’ve chosen to embrace curiosity and become proactive in learning about cancer. It’s my way of honoring their memories and empowering myself to make a difference. As I prepare for college this Fall, I’ve been reflecting on my career aspirations. My goal is to make a meaningful and purposeful impact in the field of medicine, so I’ve decided to pursue a career in nursing. This path resonates with me as it aligns with my passion for helping others and allows me to realize my professional ambitions.

The innovative technique developed by MIT researchers, along with my personal journey, has inspired me to join the fight against cancer. With a newfound understanding and determination, I eagerly look forward to pursuing a nursing career, driven by the belief that every effort contributes to better treatments and outcomes for those impacted by cancer.What’s your take on CRISPR genome-editing? Share your thoughts or any interesting facts you know!

An article titled, New findings on the link between CRISPR gene-editing and mutated cancer cells, discusses how researchers at Karolinska Institutet in Sweden have discovered that during gene editing with the CRISPR technique (Clustered Regularly Interspaced Short Palindromic Repeats). CRISPR is a component of bacterial immune systems that can break DNA and has been repurposed as a tool for gene editing. During this process, they discovered a protein called p53, which protects cells from DNA damage and gets activated. However, cells with mutated p53 have an advantage in surviving this process, which can lead to cancer.

This relates to Unit 7, Molecular Genetics, in AP Biology because we learned about how genes mutate. Gene mutation refers to a change in the nucleotide sequence of a gene. The researchers’ discovery shows how genes mutate, specifically the p52, and how that can interact with the CRISPR technique.

Furthermore, the study shows that by temporarily inhibiting p53 could minimize the buildup of mutated cells while keeping CRISPR’s efficiency intact. With this research, scientist are on the right path to creating more specific cancer treatments in the future.

Additionally, researchers discovered a network of genes associated with p53 mutations, which contribute to cell enrichment. However, temporarily blocking p53 can reduce this enrichment. The study created CRISPR experiments on isolated cells and examined a database. More study is needed to determine the scope of this problem in healthcare settings. Several research organizations funded the study.

The CRISPR technique for gene editing is beneficial to my own life as I have many family members who have battled cancer. It is extremely discouraging to watch, especially since there is no cure; however, with this technique, I am hopeful that the future will bring advancements to cancer treatment and hopefully one day put an end to the disease. SO, who else is excited to see how far in cancer studies the CRISPR technique can take us?
