  • Metabolomics is the scientific study of chemical processes involving metabolites. Specifically, metabolomics is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind", the study of their small-molecule metabolite profiles.[1] The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes.

  • Cell biology studies the structural and physiological properties of cells, including their behaviors, interactions, and environment. This is done on both the microscopic and molecular levels, for single-celled organisms such as bacteria as well as the specialized cells in multicellular organisms such as humans. Understanding the structure and function of cells is fundamental to all of the biological sciences. The similarities and differences between cell types are particularly relevant to molecular biology....

  • DNA fragmentation is a hallmark of apoptosis that occurs in a variety of cell types; however, it remains unclear whether caspase-3 is required for its induction. To investigate this, we produced caspase-3 knockout Chinese hamster ovary (CHO)-K1 cells and examined the effects of gene knockout and treatment with caspase-3 inhibitors.

  • Pigment epithelium-derived factor (PEDF), a potent blocker of angiogene-sis in vivo, and of endothelial cell migration and tubule formation, binds with high affinity to an as yet unknown protein on the surfaces of endothe-lial cells. Given that protein fingerprinting suggested a match of a 60 kDa PEDF-binding protein in bovine retina withBos taurusF1-ATP synthase b-subunit, and that F1Fo-ATP synthase components have been identified recently as cell-surface receptors, we examined the direct binding of PEDF to F1. ...

  • Cell death induction by tumor necrosis factor has been an intensively stud-ied area for the last two decades. Although it may appear that the skeleton should have been picked clean by now, new secrets about tumor necrosis factor death signaling are still being uncovered.

  • Humanb-defensin-2 (HBD-2) is an antimicrobial peptide produced by the epithelial cells that plays an important role in innate and adaptive immu-nity. Here we report that high mobility group protein N2 (HMGN2), a member of the high mobility group superfamily that affects chromatin function, modulates the expression of HBD-2 in A549 cells treated by lipo-polysaccharide.

  • Parathyroid hormone (PTH)(1–34), which has been established to have a dual effect on bone metabolism, was recently found to regulate osteosarcoma cell migration. A significant part of the bone anabolic action of PTH(1–34) is attributed to fibroblast growth factor (FGF)-2 stimulation.

  • Mobilization of hematopoietic stem and progenitor cells (HSPCs) from the bone marrow to the peripheral blood is utilized in clinical HSPC transplan-tation protocols. Retention of HSPCs in the bone marrow is determined by relationships between the chemokine chemokine (C-X-C motif) ligand 12 (CXCL12) and its major receptor

  • Chapter 11 is not that the material is so difficult, but that most of the material will be completely new to you. Cell communication is normally not covered in standard high school biology books, yet perhaps no other section of biology has grown as much as cell signaling has in the last ten years. Take your time with this section, and you will be rewarded with a knowledge base that will be most helpful in this course and courses to come.
