Breaking down AGEs: Insight into how lifestyle drives ER-positive breast cancer
Consumption of processed foods high in sugar and fat increase levels of advanced glycation end products (AGEs). Researchers report that AGE levels are higher in patients with estrogen receptor (ER)-positive than ER-negative breast cancer. Addition of AGEs caused breast cancer cells, whose growth had previously been controlled by tamoxifen, to begin to grow again. This suggests that patients with high AGEs may be less likely to respond to tamoxifen treatment.

Long-term memory encoding engram neurons are established by the transcriptional cycling
Long-term memory (LTM) is formed by repetitive training trials with rest intervals and LTM formation requires transcription factors, including CREB and c-Fos. Researchers found that ERK activity is increased during rest intervals to induce transcriptional cycling between c-Fos and CREB in a subset of mushroom body neurons. Significantly, LTM is encoded in these mushroom body neurons, and blocking outputs from these neurons suppress recall of LTM whereas activating these neurons produces memory-associated behaviors.

Scientists have discovered two successful therapies that slowed the progression of pediatric leukemia in mice, according to three studies published over the last two years. When a key protein responsible for leukemia, MLL, is stabilized, it slows the progression of the leukemia, the most recent study found.

A novel mechanism that regulates cellular injury by phagocytes during inflammation
Phagocytes such as macrophages and neutrophils contain multiple lysosomes, which possess a variety of digestive enzymes. Upon stimulation, phagocytes secrete these digestive enzymes through a process called lysosomal exocytosis to lyse external pathogens or tumor cells. A research team has identified myoferlin as a critical regulator of this process. Furthermore, they found that it plays an important role in inducing cellular injury by phagocytes during inflammation.

Himalayan marmot genome offers clues to life at extremely high altitudes
Himalayan marmots can survive at altitudes up to 5,000 meters in the Himalayan regions of India, Nepal, and Pakistan and on the Qinghai-Tibetan Plateau of China, where many of them face extreme cold, little oxygen, and few other resources. Now, researchers have sequenced the first complete Himalayan marmot genome, which may help them to better explain how the marmots live in such extremes.

How the brain reacts to loss of vision
If mice lose their vision immediately after birth due to a genetic defect, this has a considerable impact, both on the organization of the cerebral cortex and on memory. Researchers demonstrated that, in the months after blindness emerged, the density of neurotransmitter receptors that regulate excitation balance and are required for memory encoding was altered in all areas of the cortex that process sensory information. Furthermore, the hippocampus, a brain region that plays a crucial role in memory processes, was profoundly affected.

They showed that the different laminin variants affected the cells' motility, density, and interactions, resulting in their differentiation into specific ocular cell lineages. Cells cultured in this way could be used to treat various ocular diseases.

The results reveal how plants adapt to the microgravity space environment and can help guide research needed for the successful utilization of plants in future exploration initiatives.

Geneticists observed how the second X chromosome in females gradually becomes inactive in order to avoid an overdose of genes encoded by the X. They also found that several genes bypassed this inactivation, which varied according to the tissue and life phases of the cell.

This conclusion holds whether considering the 'pause' as a change in the rate of warming in observations or as a mismatch in rate between observations and expectations from climate models.

Previous evolutionary theories, based on anatomical similarities, are inaccurate, with geographically isolated populations of stick insects more likely to be related than those with similar features.
