Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
A ball and stick model of a molecule of Human Interferon. Interferons are proteins important in the working of the immune system and are produced in large numbers in the presence of viruses, bacteria, tumors and parasites.  Interferons are used in drugs to combat cancer, multiple sclerosis, hepatitis B and C and other diseases. Isolated on white.

Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
Myxoid liposarcoma.  Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body

The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,
Most osteosarcomas are high grade, meaning they will probably grow and spread quickly if not treated. The usual treatment for these cancers is as follows: Biopsy to establish the diagnosis. Chemotherapy (chemo), usually for about 10 weeks.
CD47 also known as integrin associated protein is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 and signal-regulatory protein alpha. 3D cartoon and Gaussian surface models, chain id color scheme, based on PDB 2jjt, white background
