5 Advancements Being Made in the History of Cancer Biology
The study of cancer biology and the ways to combat it is as broad as any field of science. It’s a dynamic area of research with so many discoveries being made regularly. The field has significantly evolved over the past several decades. Advancements in technology, statistics, biology, and other areas have helped scientists gain greater insight into how and why cancer occurs. Researchers are constantly coming up with new ideas for fighting cancer and finding better ways to detect it early on.
1. Time-lapse Imaging
One of the most recent technological advances being put to use in the history of cancer biology is time-lapse imaging. It’s a sophisticated imaging technique that tracks cell changes over time. Time-lapse imaging is a great way to understand how cells change in response to various conditions. It’s also beneficial for studying diseases, like cancer, that progress over time. With time-lapse imaging, researchers can observe the behavior of cells in a Petri dish over several weeks or months.
2. DNA Analysis
DNA is one of the most critical molecules in the history of cancer biology. It acts as instructions for making proteins and enzymes that keep the body healthy and functioning. DNA also provides a code that can be used to identify people and other living things. In the 1990s, DNA analysis became a widespread technology for cancer research. It allowed scientists to determine the sequence of chemical bases in a sample of DNA. They then use this sequence to identify the DNA of a particular species, such as a human, mouse, or mammal. In the case of cancer, scientists can also specify the DNA of the cells causing the tumor. This allows them to determine the type of cancer and what treatments will work best.
3. Personalized Medicine
Personalized medicine is a type of treatment that considers the individual’s biological makeup when making treatment decisions. Treatments are tailored to each patient’s genetic makeup, environment, and lifestyle factors. This allows physicians to make better-informed decisions about therapies and drug dosages. Since cancer is a congenital disease, it makes sense that physicians would want to tailor treatment to each patient’s genetic makeup. Taking a patient’s genetics into account can help doctors determine the best course of treatment for their specific situation. Developments have heavily influenced the rise of personalized medicine in the history of genetic research. It was only in the 1990s that scientists could map the human genome. This was an essential milestone for cancer biology. Identifying genetic mutations linked to an increased cancer risk made it possible.
4. Chronotherapy: Counting Down Cancer
A chronotherapy is a treatment approach that relies on cells’ circadian rhythm. It’s a strategy that involves treating cancer patients at specific times of the day. This approach is based on the fact that many biochemical reactions in cells follow a circadian pattern. Spatial Transcriptomics aids doctors in conducting this treatment approach. The most important reactions that do this are those related to DNA repair. When cells are exposed to harmful substances like cigarette smoke, they initiate a DNA repair response. This repair process is a complicated biochemical process that can take several hours. Therefore, DNA repair is most active during specific times of the day. During the rest of the day, the repair process is interrupted. This leaves DNA vulnerable to damage from harmful substances.
5. New Developments In Drug Research And Development
The history of cancer biology has seen many new discoveries that have led to drug research and development advancements. One of the most important is the discovery of the existence of receptors. These proteins are found throughout the body and are responsible for receiving chemical signals. One important receptor discovered is the epidermal growth factor receptor (EGFR). It is sensitive to a protein called the epidermal growth factor. This substance is released naturally by the body and plays a crucial role in average cell growth. Other receptors, like EGFR, can be targeted by drugs. This makes it possible to develop drugs that will stop or prevent cancer.
Conclusion
The study of cancer biology is an ever-evolving and expanding field. The past decade has brought many new discoveries, technologies, and drugs to market. These are helping doctors and researchers gain a better understanding of the disease. These advancements are helping to reduce the number of cancer-related deaths and making it easier to treat the disease.
