While mechanistic pathways associated with rhinovirus-induced airway remodeling are still not fully characterized, infected airway epithelial cells robustly produce type 2 cytokines and chemokines, as well as pro-angiogenic and fibroblast activating factors that act in a paracrine manner on neighboring airw...
the transmembrane protein PIN1 is strongly expressed in epidermal cells of the SAM and its apical polarization results in the creation of an auxin gradient with maxima directed towards sites of incipient leaf primordia [23–25,72–75] (Figure2A). This in turn acts as an auxin sink that is ...
It is a gene predominantly expressed in skeletal muscle and indispensable to muscle development and regeneration.31 Therefore, its overexpres- sion is a marker of regeneration, indicating the presence of immature muscle cells in the dystrophic muscles.32 Myl4, another regeneration marker overexpressed ...
Crop traits are inherited from parent plants through many generations and are encoded by the genetic information contained within the DNA of cells. However, the genetic contents are continuously modified (Vergauwen and De Smet2017) as a consequence of spontaneous mutations, transcriptional errors, en...

Small nucleolar RNA host gene 15 (SNHG15) and 16 (SNHG16) are both significantly increased in PC cells [59]. The upregulation of SNHG15 is significantly associated with tumor size, lymph node metastasis, and advanced TNM stage in patients with PC. Functionally, the SNHG15 combination att...
Recombinant viral vectors enable intracellular antigen expression and induce a robust cytotoxic T lymphocyte response, leading to the elimination of virus-infected cells. The advantages of viral vectors are mainly (a) high- efficiency gene transduction; (b) precise delivery of genes to target cells;...
In HER2+ and triple-negative breast cancer, the CAF subpopulation with high FAP expresses programmed death ligand-1/2 (PD-L1/2), which can bind to PD-1 expressed by T cells and directly inhibit T cell activ- ity [20]. In a mouse model of pancreatic cancer, FAP+ CAFs are ...
The remaining types are much rarer than most of those already mentioned, but they are generally moderate types that may look more like type 3 or 4. Some of these types affect your bone-forming cells instead of your collagen. Osteogenesis imperfecta life expectancy ...
