HER2 (light blue) and HER3 form a potent pro-oncogenic heterocomplex.  They play a  crucial role in cellular proliferation, survival, and differentiation.
The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.
Orange colored ball standing on the twisted wavy purple colored ribbon with blocks. (3d render)
Brain-derived neurotrophic factor (3d), also known as BDNF, a protein that supports the survival of existing neurons, and encourages the growth and differentiation of new neurons and synapses.
Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.
Aligned amino acid sequences of various individuals. The amino acids were derived from their three bases in the genetic code and seen in a DNA sequence. This type of alignment is useful in determining the relatedness of individuals. In this case the sequences were derived from the ribosomal genes of a somewhat obscure fungus not known to be of any commercial, industrial or other value.
Ring formation of thumbs ups like logos scattered into groups, symbolizing varied demographic positive opinions, crystal glass renders.

Molecular Model of Human Insulin with disulfide bonds shown.
Chronic kidney disease (CKD) is a type of kidney disease in which a gradual loss of kidney function occurs over a period of months to years. Initially generally no symptoms are seen, but later symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion.
Recombinant human insulin. 3d cartoon model based on protein data bank
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
3D rendering. The structure of the protein molecule, an activator of angiogenesis. X-ray crystalline model of one of the subunits of the hif1A molecule.
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.
HER3 belongs to the Epidermal Growth Factor Receptor (EGFR) family. It plays a crucial role in cellular proliferation, survival, and differentiation via the PI3K/Akt, MAPK, and JAK/STAT signaling pathways.

Prions are misfolded proteins with the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals.
A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
Interleukin 13 (IL-13) cytokine protein. 3D illustration. Cartoon representation with secondary structure coloring (blue sheets, red helices).

Calcitonin is a hormone that is produced in humans by the parafollicular cells (commonly known as C-cells) of the thyroid gland. Calcitonin is involved in helping to regulate levels of calcium and phosphate in the blood, opposing the action of parathyroid hormone. 3D cartoon model isolated, white background
Aligned DNA nucleotide sequences displayed on a laptop computer screen. The last four sequences have a single nucleotide polymorphism (SNP) at position 332, their is a SNP in sequences 2 and 3 at position 389.
