"Cancer cell growth depends on the production of new blood vessels by tumor endothelial cells in a process called angiogenesis. But the growing cancer cells produce large amounts of lactic acid as a byproduct of glucose breakdown. How tumor endothelial cells are able to survive in this toxic environment is unclear. In a recent study, researchers sought to uncover the mechanism of tumor endothelial cell survival in a lactic acid-rich tumor microenvironment. Using genetics and proteomics, they compared the RNA and protein levels of pH-regulating proteins in tumor endothelial cells to those in normal endothelial cells. They found that carbonic anhydrase 2 (CAII), an important pH regulator, was elevated in tumor endothelial cells, which was induced through the VEGF signaling pathway. Blocking CAII in tumor endothelial cells decreased cell survival in lactic acid conditions, and treating tumor-bearing mice with a CAII inhibitor had decreased lung metastasis..."

Following the steps of the engineering design process and acting as biomedical engineers, student teams use everyday materials to design and develop devices and approaches to unclog blood vessels. Through this open-ended design project, they learn about the circulatory system, biomedical engineering, and conditions that lead to heart attacks and strokes.

"Angiogenesis, the formation of new blood vessels, is a popular target of various therapies. Some therapies, like those used in tissue engineering, are designed to promote angiogenesis and new tissue growth, while other therapies, such as those designed to fight cancer, aim to suppress angiogenesis— a lifeline for tumor cells. Unfortunately, these therapies aren’t always effective. Now, a new mathematical model could help researchers understand what molecular levers to pull to effectively modulate angiogenesis. Trained on published experimental data, the model predicted the effects of activating two common targets of angiogenesis-based therapies: vascular endothelial growth factor, or VEGF, and fibroblast growth factor, or FGF. Computational experiments showed that the two factors modify both the ERK signaling pathway, which is linked to cell proliferation, and the Akt signaling pathway, which is associated with cell survival and migration..."

"Atherosclerosis (AS), or thickening of the arteries due to plaque buildup, is a common and potentially deadly condition. A procedure called percutaneous transluminal coronary angioplasty (PTCA) has markedly improved patient survival, but narrowing of the arteries after PTCA (restenosis) remains a problem. Unique extracellular vesicles derived from endothelial colony-forming cells (ECFC-exosomes) are known to help repair injured vessels. Therefore, a new study explored the effects of ECFC-exosomes in a human cell model and a rat model of AS-/PTCA-induced vessel injury. In lipid-injured human vascular cells, ECFC-exosomes promoted repair-related processes such as cell proliferation, migration, and tube formation by enhancing autophagy, a process in which intracellular debris is degraded and recycled. Specifically, the exosomal miRNA miR-21-5p inhibited expression of the protein SIPA1L2 to increase autophagy..."

"Congenital heart defects affect approximately 1% of all babies born each year and account for almost 20% of all newborn deaths. Early diagnosis while still in the womb can greatly improve an affected baby’s chance of survival. Unfortunately, diagnosis relies exclusively on ultrasound imaging, where accurate readings aren’t guaranteed. Researchers in Japan are tackling this problem by enlisting the help of artificial intelligence. More importantly, they’re helping the doctors entrusted with patient care to understand how AI programs spot heart defects. Advancements in artificial intelligence have improved how congenital heart defects are diagnosed. Ultrasound videos of fetal hearts beating normally and others with structural defects can be studied with AI, which can then determine whether the fetal hearts in new videos are abnormal or not..."

Students work as biomedical engineers to find liquid solutions that can clear away polyvinyl acetate polymer "blood clots" in model arteries (made of clear, flexible tubing). Teams create samples of the "blood clot" polymer with different concentrations to discover the concentration of the model clot and then test a variety of liquids to determine which most effectively breaks down the model blood clot. Students learn the importance of the testing phase in the engineering design process, because they are only given one chance to present the team's solution and apply it to the model blood clot.

"Tumor growth relies upon the production of new blood vessels, also known as angiogenesis, to supply adequate oxygen and nutrients to the cells. Angiogenesis blockade therapy was thus developed to impair blood vessel growth and cut off this supply. This is accomplished with the use of medicines targeting pro-angiogenic factors such as vascular-endothelium growth factor (VEGF), fibroblast growth factor (FGF), and stem cell factor (SCF). For example, bevacizumab is a monoclonal antibody that targets VEGF and has shown promise in combating non-small-cell lung cancer, but the use of angiogenesis inhibitors has also been linked to an increase in local tumor invasiveness and the spread of cancer to other parts of the body. New evidence suggests that these issues can be diminished by administering anti-angiogenic agents in combination with other strategies..."

This lesson contains background about the blood vascular system and the heart. Also, the different sizes of capillaries, veins, and arteries, and how they affect blood flow through the system. We will then proceed to talk about the heart's function in the blood vascular system. This will lead into a discussion of heart valves, how they work and what might cause them to fail. Then we will discuss prosthetic heart valves.

"Physicians may soon be able to get a detailed look at blood vessels surrounding breast tumors quickly, painlessly, and without radiation, thanks to the work of a team of Japanese researchers. One application of the technology is earlier and more accurate tracking of when cancer has turned deadly. The formation of new blood vessels around a tumor is a key sign that cancer is getting ready to spread. But getting a clear look at these blood vessels can be tricky. Approaches like MRI or computed tomography often come with a hefty price tag, and exposure to contrast agent or radiation may pose health risks. To sidestep these issues, the researchers optimized a way to perform photoacoustic imaging. This type of imaging utilizes the light-absorbing properties of hemoglobin to show where blood is flowing in the body. When hemoglobin is exposed to pulses of laser light, it produces small vibrations. These vibrations are picked up by scanners and used to generate a detailed map of blood vessel architecture..."
