Stress, such as neuroexcitotoxicity and oxidative stress, as well as traumatic brain injury, will result in neurodegeneration. Deciphering the mechanisms underlying neuronal cell death will facilitate the development of drugs that can promote neuronal survival and repair through neurogenesis. Many growth and trophic factors, including transforming growth factors (TGFs), insulin-like growth factors (IGFs), epidermal growth factor (EGF), fibroblast growth factor 2 (FGF2), and brain-derived neurotrophic factor (BDNF), are known to play a role in neuroprotection and neurogenesis.

Formation of multinucleated osteoclasts depends on an oxidized species of cell surface-associated La protein.

Elife

October 2024

Section on Membrane Biology, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, United States.

Article Synopsis
  • Osteoclasts are special cells that help break down bone, and they work together to keep our bones healthy throughout our lives.
  • A protein called La is found on the surface of these cells, and it helps them fuse and become more powerful in breaking down bone.
  • Scientists discovered that a certain type of chemical signal, called reactive oxygen species (ROS), changes the La protein, helping it move to the surface and making the osteoclasts better at their job, which could lead to new treatments for bone diseases.

Front Endocrinol (Lausanne)

October 2024

Section on Medical Neuroendocrinology, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD, United States.

Few reports have highlighted the rare presence of somatic variants in clinically aggressive, metastatic pheochromocytoma/paraganglioma (PCC/PGL); however, none have addressed detailed clinical presentation (including biochemistry and imaging) and management of these patients. Here, we address these clinical features and management based on four PCC patients with somatic variants from our National Institutes of Health PCC/PGL cohort. A total of 192 patients underwent exome sequencing (germline, somatic, or both), and four males were found to have somatic variants (with additional somatic and oncogenic variants in patients 2 and 4, respectively).

One species-general life history (LH) principle posits that challenging childhood environments are coupled with a fast or faster LH strategy and associated behaviors, while secure and stable childhood environments foster behaviors conducive to a slow or slower LH strategy. This coupling between environments and LH strategies is based on the assumption that individuals' internal traits and states are independent of their external surroundings. In reality, individuals respond to external environmental conditions in alignment with their intrinsic vitality, encompassing both physical and mental states.
