Posted by Biotechnology is revolutionizing healthcare, agriculture, and industry – from personalized medicine to 3-D bioprinting – it holds endless promise.
Pfizer and Moderna’s use of biotechnology to quickly respond to global health crises through the COVID-19 pandemic proved its usefulness; other innovations, including recombinant DNA technology and genome sequencing, are accelerating medical advances as well.
Recombinant DNA
Recombinant DNA technology allows scientists to combine DNA segments from different organisms for specific uses, revolutionizing biotechnology and medicine while opening doors to scientific advances that further our understanding of life.
DNA (deoxyribonucleic acid) is a double-helix structure composed of four nitrogen bases — adenine, thymine, guanine, and cytosine – organized in specific combinations to form specific DNA sequences. Scientists can combine the nitrogen bases in various ways to create new combinations known as recombinant DNA (rDNA).
Scientists use recombinant DNA technology to produce human therapeutic proteins that can be used in therapy. One such example dates back to Genentech’s development of an industrial process for producing recombinant insulin in the 1970s; today pharmaceutical companies rely heavily on this process as it provides more consistent production than natural sources like blood or tissues from humans or animals.
Recombinant DNA technology’s most revolutionary application is gene therapy, which seeks to treat disease by replacing disease-causing genes with functional ones. Although still experimental in its effectiveness, recombinant DNA technology has allowed researchers to create innovative cancer treatment approaches and gene therapies for hereditary conditions like cystic fibrosis, Gaucher’s disease, severe combined immunodeficiency disease and hemophilia A.
Recombinant DNA techniques are essential in the production of genetically modified organisms (GMOs). Genetically engineered crops may provide better resistance against pests, drought and salt stresses while being more economically and socially sustainable than their conventional counterparts. However, GMO risks must be balanced against economic and social benefits before being approved for production.
Monoclonal Antibody (mAb) Therapy
Antibodies are protein molecules produced by our bodies to defend against foreign substances, while monoclonal antibodies are laboratory-made versions used to treat illnesses and conditions such as cancer, autoimmune diseases, and infectious diseases like COVID-19.
To produce monoclonal antibodies (mAbs), B cells must first be immunized against an antigen of interest. Once produced, these mAbs can then be directed against their target antigen to induce cell death or signaling cascades – this process is known as cellular immunotherapy. Additionally, these mAbs have numerous applications in treating various illnesses and conditions as they can inhibit tumor growth, limit cancer cell spread, block inflammation-causing signals, and more.
The first monoclonal antibody was approved in 1986 for transplant rejection treatment (OKT3) and today there are hundreds of different mAb therapies developed to address oncological and immunological targets, as well as prevent or treat hemophilia A (congenital Factor VIII deficiency) with factor replacement therapy.
mAbs are administered via intravenous infusion. They should only be given in settings with immediate access to medications that can treat serious infusion reactions, and interactions may arise with other drugs or trigger adverse events, so patients must follow instructions from their healthcare providers carefully.
Biotech companies are working diligently to develop safer and more effective mAb treatments, known as personalized medicine. Personalized medicine uses tests that assess how a patient’s genetic makeup and other health characteristics will impact how their response to a certain drug.
Biotech innovations have also allowed for faster vaccine development. Pfizer and Moderna’s rapid creation of mRNA-based vaccines against the COVID-19 pandemic, adaptable to its variants, was an impressive example of biotech innovation at work in preemptive biodefense – this proved that personalized, fast-acting vaccination can deliver targeted therapy more effectively to patients – an exciting prospect that gave healthcare a brighter future than ever.
Genetic Sequencing
Genome sequencing (DNA sequencing) has revolutionized medical research by enabling scientists to quickly and accurately identify an individual’s genes quickly. In medicine, this can help detect mutations underlying diseases like epilepsy and cancer as well as assess risk for certain illnesses that could lead to preventative therapies or early diagnosis.
Innovations like these are contributing to a new treatment paradigm known as personalized medicine, which seeks to tailor therapies specifically to an individual’s conditions, health traits, and genes. Pharmacogenomics has already proved instrumental in this regard by helping inform medication choices by determining whether certain genes make certain medicines more or less likely to work.
Molecular techniques are being applied to create vaccines more quickly and precisely. Moderna’s COVID-19 vaccine, approved for emergency use in 2021 via its mRNA technology platform, proved the ability of biotechnology companies to rapidly respond to global health threats by creating effective vaccines against fast-emerging pathogens.
Genomic sequencing allows researchers to gain a better understanding of how different mutations in genes affect disease development and response to medications. With this information at their disposal, scientists will be better equipped to create predictive tests that predict someone’s risk of disease development and improve clinical trial design.
Genomic sequencing also offers researchers the unique opportunity to compare large stretches of DNA across samples from multiple individuals, giving researchers valuable clues into how different genes influence disease development. Unfortunately, widespread adoption of next-generation sequencing technologies (NGS) remains challenging due to high upfront costs and potential sensitivity issues.
Genomic sequencing is being utilized to explore the possibilities of gene editing through CRISPR-Cas9 technology, which cuts or modifies existing genes’ functions. This has the potential of treating hereditary conditions like sickle cell disease, hemophilia, and Huntington’s disease by inserting corrective genes or replacing mutation-causing ones with functional counterparts – this field of research promises great progress, but more work must be conducted in humans to validate its methods and identify any safety concerns.
Pharmaceutical Development
Technology continues to rapidly advance, leading to groundbreaking medical and biological advancements that promise transformative effects for human health and medicine; such as being able to prevent, diagnose, and treat once-incurable diseases more easily than ever.
Pharmaceutical development advances are among the many advantages offered by biotechnology, enabling doctors to prescribe tailored medications suited specifically for each individual’s conditions and genetic makeup. One such drug is Herceptin (trastuzumab), a monoclonal antibody that revolutionized the treatment of HER2-positive breast cancer with extended survival rates by three years and offered hope of a future where incurable illnesses could be managed or even eradicated.
Biotechnology has also hastened the development of lifesaving vaccines such as the COVID-19 vaccine, which was created and approved in less than one year – another example of biotechnology’s transformative power in healthcare and medical research.
Biotechnology can also revolutionize genomic research, revolutionizing how researchers study the body and develop therapies. Researchers use genomic data to create models that predict how drugs might react in various bodies – speeding up the search for more effective drugs.
However, much work remains in drug discovery and development. Biotech solutions utilizing biological “big data” may prove ineffective if collected without taking a representative sample from within its target population or when there are racial and cultural biases present in its collection process.
Increased representation of underrepresented groups in biological sciences is vital for biotech innovation and advancement. Furthermore, as we collect digital health and well-being data such as apps that track sleep and mood or radiographs and pathology images from patients or radiographs and pathology images from radiology departments or hospitals we must use this insight for good and not reinforce existing inequities. To do so will require genuine engagement with healthy individuals or patients as well as intentional efforts to enhance diversity within translational research – only then will biotech’s power unleash its full potential to unlock an improved future for all.
