Gestational diabetes can cause a multitude of complications in the offspring, but to date, the reasons are incompletely understood. A new study, exploring a foundational step in the process of building proteins from genetic material, called splicing, reveals that this process is affected, altering how the placenta reads and processes genetic instructions. Researchers found that in pregnancies affected by gestational diabetes , hundreds of genetic messages are assembled incorrectly, potentially disrupting how the placenta functions. They identified a key protein, SRSF10, that appears to contribute to the disrupted process. . When this protein was blocked in lab cells, the same errors seen in gestational diabetes appeared, suggesting that targeting SRSF10 could one day help mitigate the deleterious effects of gestational diabetes on the offspring.

New study uncovers an unknown mechanism linking gestational diabetes to pregnancy complications. Gestational diabetes mellitus (GDM), a form of diabetes that develops during pregnancy, has an increasing prevalence worldwide. GDM causes a disrupted metabolic environment for the fetus, including elevated blood glucose levels from the mother. This may result in immediate complications for the newborns, such as being born too large or too small for gestational age, more caesarean deliveries, pre-term deliveries, and more. . It also has long-lasting effects on the offspring, with higher risks for obesity and diabetes later in life. A new study led by Prof. Maayan Salton from the Faculty of Medicine at the Hebrew University of Jerusalem and Dr. Tal Schiller from the Faculty of Medicine at Hebrew University, Kaplan Medical Center, and Wolfson Medical Center at Tel Aviv University, reveals that gestational diabetes alters the placenta at the molecular level in ways never seen before. Published in Diabetes, a leading journal in the field, the study found that GDM changes how the placenta processes its genetic messages. Using advanced RNA sequencing data from both European and Chinese pregnancy cohorts, the team discovered hundreds of alterations in how RNA molecules are "spliced", the step that determines which protein instructions are ultimately produced. These changes were strongly linked to genes involved in metabolism and diabetes-related pathways. A key finding centered on SRSF10, a protein that helps control RNA splicing. When researchers reduced the activity of SRSF10 in placental cells, the same molecular disruptions seen in GDM appeared. This suggests that SRSF10 may be a master regulator of placental function, and potentially a new therapeutic target for preventing pregnancy complications.

By understanding how gestational diabetes disrupts the placenta at the molecular level, we can begin to imagine new ways to protect the offspring" said Prof. Salton. "Our findings bring us a step closer to that goal. By pinpointing the specific molecular players involved, like the SRSF10 protein, we can start thinking about how to translate this knowledge into real-world strategies to improve pregnancy outcomes."

Gestational diabetes is typically managed through diet, exercise, and insulin, but its underlying biology has remained poorly understood. This research sheds light on how the metabolic changes observed in GDM can alter how genes are processed, opening new avenues for intervention.

01ApconiX's in vitro seizure liability assay (iSLA) platform provides a human-relevant approach for assessing seizure liability. Where can AI add the most value alongside assays like this?

There are several areas where AI could add value, but one of the most exciting is helping us translate complex experimental results into actionable insights for drug discovery teams. We see computational and experimental approaches as complementary rather than competing technologies. In vitro assays such as iSLAseizure generate highly relevant biological data, while AI and machine learning can help uncover patterns within that data that might otherwise be difficult to identify. One example is work I recently presented at the BioNow BioAI Symposium, in which we explored the use of structure-activity relationships (SAR) and machine learning models alongside iSLAseizure assay data. Supported by colleagues, including Dr. Louisa Zolkiewski and Dr. Kim Rockley, ApconiX has developed an in-house seizure liability dataset that we analyzed in collaboration with MedChemica. Using machine learning and chemical informatics approaches, we identified chemical substructures that show statistically significant relationships with seizure-related outcomes. The aim is not simply to predict risk, but to understand which molecular features may contribute to that risk and provide medicinal chemists with practical guidance they can apply much earlier in the discovery process. Looking ahead, I think this is where AI can have a particularly powerful impact. Rather than acting as a standalone prediction tool, it can work alongside human-relevant assays such as iSLAseizure to connect molecular structure, experimental biology, and safety outcomes. That combination has the potential to improve decision-making earlier in the discovery process, reduce late-stage safety surprises, and ultimately support the development of safer medicines for patients.

02What is deep learning and how do you think it could be used to improve the drug discovery paradigm?

You're average biomedical researcher is dealing with a huge amount of new information every day. You're getting over 10,000 new publications uploaded on a daily basis worldwide across all the biomedical journals and databases, so there is no way that one researcher can actually even access, let alone read all these huge amounts of data. What we have to do is use deep learning to be able to help us ingest all that data and do some initial deep triage of that data to surface new therapeutic opportunities. It’s meant to provide insight for our biologists and chemists, so they can actually deal with a usable amount of information.

03Could daraxonrasib be effective against other cancer types?

RAS mutations are one of the most common cancer-causing genetic mutations, and the drug is now being studied in several cancer types. I think it's going to work especially well in tumors that are primarily RAS driven, including colon cancer and lung cancer. It might also work in other cancer types in combination with drugs targeting other genetic mutations, but further research is needed.

04Are supplements necessary?

Daily, if you eat a balanced diet that includes healthy foods, you technically should not need a vitamin supplement. A healthy diet incorporates lean proteins, healthy fats, grains, fruits, and vegetables. But if you do not have a balanced diet, you may be considering hair, skin, and nail vitamins. Some people prefer supplements, sometimes choosing a multivitamin that can supply all of your essential minerals and vitamins. But taking too much of vitamins or unnecessary supplements is wasteful because the body gets rid of excess vitamins and minerals or, worse, it can be dangerous. The following is a guide to choosing which vitamins you may want to consider supplementing and when. Deficiencies in the nutrients that keep the skin, hair, and nails healthy can cause changes over time. For example, not enough intake of vitamins A and E, along with not enough biotin, can cause scaly and rough skin patches, eczema, and hair loss. If there is a deficiency, vitamins will help. However, if there is no deficiency, there is no clear evidence that supplements will make a difference. No research studies concluded that supplements treat or prevent age-related, natural hair damage or loss or lead to healthier skin. Two studies in the early 1990s did suggest that a biotin supplement may cause the hair to become stronger and strengthen weak nails. However, the studies were small and not reproduced.

05From Spirulina to Seaweed: How are different types of algae integral to human diets?

Algae are photosynthetic aquatic creatures that grow through the consumption of nutrients, light, and carbon dioxide. They are a diverse group of creatures that include tiny single-celled algae and enormous kelp, as well as seaweed 1. Numerous prokaryotic and eukaryotic algae species are desirable food sources for humans due to their inherent qualities 2,3. Human intake of macroalgae such as seaweed and microalgae like phytoplankton dates back many years. Multicellular macroscopic aquatic plants, or macroalgae, are classified into three taxa: Phaeophyceae, or brown algae, Rhodophyta or red algae, and Chlorophyta or green algae. Microalgae, the unicellular counterpart of macroalgae, are categorized in a broader framework that includes prokaryotic cyanobacteria (blue-green algae), Euglenophyta, and Chlorophyta, which are genetically distinct from one another. The ancient populations of Chad and the Aztec culture were already familiar with the cyanobacteria spirulina, which is currently advertised as a superfood in the West 4. In Burma, Vietnam, and India, other cyanobacteria/microalgae, like Spirogyra and Oedogonium, were eaten as food or as a supplement 4. Seaweed is a staple of daily meals in many Asian and Pacific civilizations, including Korea, Japan, and Indonesia, as well as Hawaii and New Zealand 5.
