A Better Algorithm for Predicting How Cells Behave

In a preprint published in arXiv, researchers from Altos Labs have described a machine learning algorithm that performs end-to-end prediction of how cells’ gene expression will respond to interventions. The

Cardiovascular Health During the Menopausal Transition

A recent study compared premenopausal, perimenopausal, and postmenopausal women’s cardiovascular health. Perimenopausal women had about twice the odds of having a poor overall score when compared with premenopausal women, after

How Omega-3 Fatty Acids May Alleviate Kidney Disease

Researchers have discovered the role of cellular senescence in the interaction between omega-3 polyunsaturated fatty acids (PUFAs) and chronic kidney disease (CKD). Previous mixed results Several clinical trials have found

Untangling Cellular Senescence at Its Roots

In Aging Cell, researchers have described the differences between primary and secondary senescent cells, comparing radiation-induced senescence to senescence induced by the senescence-associated secretory phenotype (SASP). Heterogeneity on top of

Reason Interview

Developing a Drug To Reverse Heart Disease

We have spoken with Reason from Repair Biotechnologies about his company’s lead candidate, REP-0004, a drug targeting the liver to reduce excess intracellular free cholesterol. The FDA has granted Repair

Current Clinical Trials of Alzheimer’s Drugs

This month, a group of researchers published an annual report on the clinical trials that are testing drugs for Alzheimer’s disease. Overall, they reported an increase in the number of

Harvard Publishes a Longevity Report for the General Public

The report, titled “Pathways to Longevity”, introduces several important longevity concepts to the general reader and is another sign that the field is coming of age and entering the mainstream. People do want to live longer From time to time, Harvard Health Publishing issues Special Health

A Better Algorithm for Predicting How Cells Behave

In a preprint published in arXiv, researchers from Altos Labs have described a machine learning algorithm that performs end-to-end prediction of how cells’ gene expression will respond to interventions. The need for prediction Simulating biological processes on a computer is an incredibly difficult task. While advanced

Early Cancer Cells Change Their Surroundings to Form Tumors

Scientists have demonstrated how cancer cells influence neighboring cells to create a favorable niche for the tumor to grow. Understanding this can inform future early-stage cancer therapies [1] Cancer is a disease of aging. With the exception of childhood cancers, most of which stem from inherited

Cardiovascular Health During the Menopausal Transition

A recent study compared premenopausal, perimenopausal, and postmenopausal women’s cardiovascular health. Perimenopausal women had about twice the odds of having a poor overall score when compared with premenopausal women, after adjusting for age [1]. Menopausal health decline The menopausal transition, and the associated changes in hormonal

Tau Protein Is Crucial for Encoding Long-Term Memory

Scientists have uncovered an unexpected function of the tau protein, which is mostly known for its role in Alzheimer’s and related disorders: helping encode long-term memory. This can inform novel approaches that target tau [1]. In sickness and in health Tau is a protein found mainly

How Omega-3 Fatty Acids May Alleviate Kidney Disease

Researchers have discovered the role of cellular senescence in the interaction between omega-3 polyunsaturated fatty acids (PUFAs) and chronic kidney disease (CKD). Previous mixed results Several clinical trials have found that taking omega-3 PUFAs has benefits for older people. One study found that it reduces the

Mitochondrial membrane

Mitochondrial Aging Linked to Losing Crucial Membrane Lipid

Scientists have found that the levels of phosphatidylcholine, the most abundant lipid in mitochondrial membranes, decline with age, driving mitochondrial aging in worms and possibly humans. Supplementing the lipid helped in an in vitro experiment [1]. What drives mitochondrial aging? Mitochondria are the cell’s energy-generating organelles,

Cataracts

How an Oxidative Stress Regulator Makes Cataracts Worse

Researchers have outlined a key receptor and protein involved in the formation of cataracts, paving the way for potential treatments targeting them. Oxidative stress and cataracts are closely related Cataracts, which cloud the lenses of the eye, are one of the most common sources of age-related

Identifying DNA

Untangling Cellular Senescence at Its Roots

In Aging Cell, researchers have described the differences between primary and secondary senescent cells, comparing radiation-induced senescence to senescence induced by the senescence-associated secretory phenotype (SASP). Heterogeneity on top of heterogeneity It is well-known that senescent cells are highly heterogenous [1]; senescent cells from one tissue

Targeting cancer

CRISPR-Based System Targets RNA and Kills Cells on Demand

Scientists have devised a CRISPR-based tool that can kill cells carrying a specific strand of RNA. The tested targets include cancerous and virus-infected cells [1]. Targeted assassination of cells CRISPR-based systems work by cutting or changing DNA at a particular spot, an ability that can be

Reason Interview

Developing a Drug To Reverse Heart Disease

We have spoken with Reason from Repair Biotechnologies about his company’s lead candidate, REP-0004, a drug targeting the liver to reduce excess intracellular free cholesterol. The FDA has granted Repair Bio an orphan drug indication, and the company is aiming for clinical trials by mid-2027. Our

New mRNA Therapy Destroys Cancer by Improving T Cell Priming

Scientists have found a way to drastically ramp up mouse immune responses to cancer along with flu and COVID-19 [1]. How to wake up the immune system Modern cancer immunotherapies only work for a minority of patients. The reason, broadly, is that many tumors are immunologically

Matthew O’Connor on Cyclarity’s Successful Phase 1 Trial

Most cardiovascular trials focus on lowering LDL cholesterol or reducing inflammation to slow disease progression. UDP-003 targets the root cause: toxic 7-ketocholesterol (7KC) inside macrophages and soft plaques. It is designed to convert bloated foam cells back into healthy macrophages that can actively clear the hard

Current Clinical Trials of Alzheimer’s Drugs

This month, a group of researchers published an annual report on the clinical trials that are testing drugs for Alzheimer’s disease. Overall, they reported an increase in the number of trials, with 158 drugs investigated across 192 trials [1]. A growing problem The projections regarding the

GLP-1 Drugs’ Muscle Effects Similar to Ordinary Weight Loss

A new study suggests that GLP-1 receptor agonists do not affect muscle mass any more than weight loss caused by caloric restriction, and this appears to be true for strength as well [1]. What do we lose when we lose weight? GLP-1-based drugs, such as semaglutide
