Scientists discover arginine drives metabolic reprogramming to promote tumor growth in liver cancer

Cancer cells are chameleons. They completely change their metabolism to grow continuously. University of Basel scientists have discovered that high levels of the amino acid arginine drive metabolic reprogramming to promote tumor growth. This study suggests new avenues to improve liver cancer treatment.

The liver is a vital organ with many important functions in the body. It metabolizes nutrients, stores energy, regulates the blood sugar level, and plays a crucial role in detoxifying and removing harmful components and drugs. Liver cancer is one of the world’s most lethal types of cancer. Conditions that cause liver cancer include obesity, and hepatitis C infection. Early diagnosis and appropriate therapeutic strategies are crucial for improving treatments in .

In the past decade, scientists have made much progress in understanding the multiple facets of cancer. Historically, it has long been viewed as a disorder in . However, there is growing evidence that cancer is a .

Atrial Septal Defect and Ventricular Septal Defect in Children

Transcatheter repair

A transcatheter repair, also called transcatheter device closure, is usually recommended for an atrial septal defect. During this procedure, a pediatric interventional cardiologist makes an incision in the groin, inserts a catheter, and funnels a small mesh patch through the catheter and up to the hole in the heart. Over time, the child’s own heart tissue grows over the patch.

A Scanner Darkly

America in the near future has lost the war against drugs. Paranoia reigns as 2 out of every 10 Americans have been hired by the government to spy on the other 8 in the name of national security and drug enforcement. Enter Fred, a reluctant undercover cop recruited by the government. To maintain his cover, Fred regularly ingests the popular Substance D. The drug has caused Fred to develop a split personality, of which he is unaware; his alter ego is Bob Arctor, a drug dealer. Fred’s superiors set up a hidden holographic camera in his home as part of a sting operation to snare Bob. A “scramble suit” that changes his appearance allows Fred to appear on camera as Bob and prevents his colleagues from knowing his true identity. The camera in Fred/Bob’s apartment reveals that Bob’s friends regularly betray one another for the chance to score more drugs.

Treatment strategies for stage IV lung cancer

Paul Bunn, MD, University of Colorado Cancer Center, Aurora, CO, discusses the survival rates of patients with stage IV lung cancer, which remain suboptimal. For patients who have a high PD-L1 tumor proportion score (TPS), approximately a third of patients survive 5 years after initial diagnosis, and further statistical analysis is required to assess whether co-morbidities contribute to patient mortality after the 5 year mark. Despite the lack of available therapies for patients with late stage lung cancer, Prof. Bunn highlights treatment options for early stage lung cancer including immunotherapy and tyrosine kinase inhibitors (TKIs) for patients with driver mutations. This interview took place at the 2022 Targeted Therapies of Lung Cancer Meeting (TTLC 2022).

Brain-computer interfaces could let soldiers control weapons with their thoughts

Imagine that a soldier has a tiny computer device injected into their bloodstream that can be guided with a magnet to specific regions of their brain. With training, the soldier could then control weapon systems thousands of miles away using their thoughts alone. Embedding a similar type of computer in a soldier’s brain could suppress their fear and anxiety, allowing them to carry out combat missions more efficiently. Going one step further, a device equipped with an artificial intelligence system could directly control a soldier’s behavior by predicting what options they would choose in their current situation.

While these examples may sound like science fiction, the science to develop neurotechnologies like these is already in development. Brain-computer interfaces, or BCI, are technologies that decode and transmit brain signals to an external device to carry out a desired action. Basically, a user would only need to think about what they want to do, and a computer would do it for them.

BCIs are currently being tested in people with severe neuromuscular disorders to help them recover everyday functions like communication and mobility. For example, patients can turn on a light switch by visualizing the action and having a BCI decode their brain signals and transmit it to the switch. Likewise, patients can focus on specific letters, words or phrases on a computer screen that a BCI can move a cursor to select.

Rare mutation may counteract “Alzheimer’s gene”

The challenge: There are very few ways to slow down Alzheimer’s disease or treat its symptoms, and there’s no cure — in 2021, nearly 120,000 Americans died from Alzheimer’s complications, making it one of the top 10 leading causes of death.

One genetic variant in particular — called APOE-e4 — is strongly tied to the brain disease. Having one copy makes a person 2–3 times more likely to develop Alzheimer’s, while having two copies (one from each parent) increases the risk by 8–12 times.

Aspire #02 — Rohit Singla: Using AI to Develop New Treatments in Kidney Disease

Rohit Singla, an MD/PhD student, shares how his training in both medicine and engineering is allowing him to identify complex problems, understand the nuances within them and tackle those complex problems with elegant solutions that are the right fit for patients with kidney disease. Using data from over 10,000 cases, he is creating artificial intelligence tools to automatically detect microscopic changes in the kidney structure and develop new treatments to improve people’s lives.
