Knockout or treatment with an antagonist of formyl peptide receptor 1 protects mice from sepsis by inhibiting inflammation.

Background: Sepsis is an infection-related systemic inflammation with high mortality rates. Activation of formyl peptide receptor 1 (FPR1) in immune cells can promote their chemotaxis and inflammatory response, which imbalances immune response during the process of sepsis. FPR1 blockade did diminish systemic inflammatory response during bacterial infection.

LncRNA TCL6 regulates miR-876-5p/MYL2 axis to suppress breast cancer progression.

We explored the influence of the TCL6/miR-876-5p axis on breast cancer cell proliferation and migration. Using The Cancer Genome Atlas (TCGA) database, we evaluated the expression of TCL6 in breast cancer patients and studied its effects on cell proliferation, migration, and the cell cycle in vitro.

Deciphering olfactory receptor binding mechanisms: a structural and dynamic perspective on olfactory receptors.

Olfactory receptors, classified as G-protein coupled receptors (GPCRs), have been a subject of scientific inquiry since the early 1950s. Historically, investigations into the sensory mechanisms of olfactory receptors were often confined to behavioral characteristics in model organisms or the expression of related proteins and genes. However, with the development of cryo-electron microscopy techniques, it has gradually become possible to decipher the specific structures of olfactory receptors in insects and humans.
