Medical Biotechnology: Unlocking the Future of Health

Explore the definition of biotechnology, its types and applications, including bioinformatics and computational biology, omics, and pharmacogenomics for drug discovery.

Explore the diverse types of biotechnology—from bioinformatics and green biotechnology to white, red, blue, and yellow biotechnologies—and their practical applications in crops, medicine, and industry.

Explore neoplasm and tumor concepts, distinguishing benign from malignant growth. Learn the nomenclature with examples like fibroma, chondroma, osteoma, and adenoma.

Benign tumors grow slowly and are encapsulated by a fibrous capsule, whereas malignant tumors grow rapidly, invade, metastasize, and display anaplastic, pleomorphic, and poorly differentiated cells.

Explore the molecular basis of cancer by examining proto-oncogenes, oncogenes, and tumor suppressor genes, and show how mutations and translocations drive unregulated cell growth.

Explore how cancer staging defines tumor size, spread to lymph nodes, and metastasis using TNM and numeric systems, guiding local versus systemic treatments and adjuvant strategies.

Contrast normal and cancer cells by showing normal cells follow a regulated cell cycle and undergo apoptosis, while cancer cells lose control and invade organs via blood or lymph.

Compare normal cells that follow cell cycle control and differentiation with cancer cells that bypass control, undergo necrosis, and metastasize by degrading basement membrane and extracellular matrix.

Explore therapy and its forms, from plant-based phytotherapy to antibiotics, and examine mechanisms of action such as cell wall inhibition, DNA replication, and protein synthesis.

Compare somatic and germline gene therapy, including ex vivo and in vivo delivery, where somatic edits affect non-sex cells and germline edits are heritable.

Explore how engineered viral vectors deliver therapeutic DNA in gene therapy, focusing on retroviruses and adenoviruses, integration into the host genome, insertional mutagenesis risk, and pseudotyped lentiviral vectors.

Explore non-viral vectors for gene therapy, including needle method, electroporation, gene gun, sonoporation, and lipofection, with large-scale production and low immunogenicity, achieving transfection efficiencies similar to viral methods.

Learn about monoclonal antibodies, monospecific clones bound to a single epitope, produced by hybridomas from mouse spleen and myeloma cells via polyethylene glycol fusion and HAT selection.

Purify monoclonal antibodies by screening hybridomas with ELISA for strong epitope binding, then purify via centrifugation, filtration, ultrafiltration, dialysis, and ion exchange or Protein A affinity chromatography.

Learn the types of monoclonal antibodies in cancer therapy, from naked antibodies like Alemtuzumab and Trastuzumab to conjugated antibodies (radiolabeled and antibody-drug conjugates) and bispecific antibodies such as Blinatumomab.

Explore the programmed cell death process of apoptosis, focusing on the intrinsic mitochondrial pathway driven by the BCL-2 family, Bax/Bak pore formation, cytochrome c release, and caspase activation.

Explore the intrinsic mitochondrial apoptotic pathway, detailing BCL2 family roles, cytochrome c release, the apoptosome, and the caspase cascade triggered by p53 and DNA damage.

Explore the extrinsic death receptor pathway of apoptosis, detailing death-inducing signaling complex formation, initiator and executioner caspases, and how external ligands trigger programmed cell death.

Explore the differences between apoptosis and necrosis, contrasting programmed, energy-dependent cell death with uncontrolled, inflammatory necrosis, including ATP use, membrane integrity, DNA fragmentation, and genetic regulation.

Explore inactivated or killed vaccines produced from whole agents by heat or chemicals, their safety, stability, booster needs, and examples like polio and rabies.

Subunit vaccines use specific antigen fragments or epitopes for safer immunity, avoiding live pathogens; recombinant production and conjugation boost immunogenicity, with Haemophilus influenzae type B and pneumococcal vaccines as examples.

Explore peptide vaccines as targeted subunits, emphasizing exposed epitopes and conserved regions; examine malaria vaccine candidates from merozoite surface protein three and the concept of toxoids.

Apply therapeutic enzymes DNase I and alginate lyase to reduce cystic fibrosis airway obstruction by degrading DNA and alginate in biofilms, improving mucus clearance and antibiotic efficacy.
