Neuroendocrine carcinoma well differentiated (carcinoid) rectum with immunostain synaptophysin
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
Backgrounds of Bacteria and Mold under the microscope in Lab.
Close up of cristal beads
p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.
Particles, medical concept
Spike glycoprotein homotrimer, a main target for neutralization antibody, to bind its receptor, ACE2, and mediate membrane fusion and virus entry. 3D cartoon and Gaussian surface models, white background.
Quantum Gravity 3d rendered image of a comprehensive exploration of Quantum Gravity theories. String theory, loop quantum gravity (LOG), causal dynamical triangulation, twistor theory, gravitational waves, spacetime, gravity waves, quantum mechanics, quantum entanglement concepts.
Spike protein of SARS-CoV-2, Mutation in the spike protein that the virus uses to bind to the human ACE2 receptor. Mutation sped up spread of coronavirus.

Overhead aerial drone view of oyster farm racks at low tide, flying at a low altitude to be able to see the detail of the oyster racks and seaweed. Located in a tidal estuary in Sutherland, Scotland. the low tides enable workers to access the racks for turning the oysters as they grow. Oysters have been farmed for many hundreds of years using this method. Seaweed has grown around the metal lines of racks.
From left to right: the NMDA and  AMPA receptors transport calcium cations into neurons after being activated by the neurotransmitter glutamate and  the GABA receptor (right) transport chloride anions after the activation by gamma aminobutyrate. PDB entries: 6wht,  3kg2, 6d6u

Microscopic photograph of a professionally prepared slide demonstrating vulvar malignant melanoma. Melanomas of the vulva and vagina are rare, accounting for no more that 2% of melanomas among women. Melanoma of the vulva behaves like melanoma in any other location and may affect a much younger population.

HER2 (light blue)  locked in the inactive conformation by Trastuzumab (left) and Pertuzumab. Trastuzumab has drastically improved the prognosis of HER2-positive breast cancer patients.
Creative seamless pattern with hand drawn textures. Abstract background. Polka dot pattern.
Complement component 3, often simply called C3, is a protein of the immune system. It plays a central role in the complement system and contributes to innate immunity. 3D cartoon and Gaussian surface models with differently colored protein chains, white background.
