1.

Ubiquitination

The process in which one or more ubiquitin groups are added to a protein. [GOC:ai] [from GO]

MedGen UID:
276919
Concept ID:
C1519751
Molecular Function
2.

Glucose

A hexose with an aldehyde group; in which each of the 5 remaining carbons other than the aldehyde group has one hydroxyl group in the R,S,R, and R configuration counting from the first hydroxyl containing carbon next to the aldehyde in the straight chain (Fisher) projection; otherwise all carbons have exclusively hydrogens. Occurs mostly as pyran (6-membered oxygen containing ring or oxane) and rarely as furan (5-membered oxygen containing ring) or straight chain. When glucose forms a ring an additional ""anomeric"" asymmetric carbon is created which is denoted as ""alpha"" or ""beta"". For isomers see http://en.wikipedia.org/wiki/Glucose. [from NCI]

Gluconeogenesis

The process of making glucose (sugar) from its own breakdown products or from the breakdown products of lipids (fats) or proteins. Gluconeogenesis occurs mainly in cells of the liver or kidney. [from NCI_NCI-GLOSS]

Insulin

Insulin (51 aa, ~6 kDa) is encoded by the human INS gene. This protein is involved in the direct regulation of glucose metabolism. [from NCI]

Proteasome Pathway

The proteasome is a protein-destroying apparatus involved in many essential cellular functions, such as regulation of cell cycle, cell differentiation, signal transduction pathways, antigen processing for appropriate immune responses, stress signaling, inflammatory responses, and apoptosis. It is capable of degrading a variety of cellular proteins in a rapid and timely fashion and most substrate proteins are modified by ubiquitin before their degradation by the proteasome. The proteasome is a large protein complex consisting of a proteolytic core called the 20S particle and ancillary factors that regulate its activity in various ways. The most common form is the 26S proteasome containing one 20S core particle and two 19S regulatory particles that enable the proteasome to degrade ubiquitinated proteins by an ATP-dependent mechanism. Another form is the immunoproteasome containing two 11S regulatory particles, PA28 alpha and PA28 beta, which are induced by interferon gamma under the conditions of intensified immune response. Other regulatory particles include PA28 gamma and PA200. Although PA28 gamma also belongs to a family of activators of the 20S proteasome, it is localized within the nucleus and forms a homoheptamer. PA28 gamma has been implicated in the regulation of cell cycle progression and apoptosis. PA200 has been identified as a large nuclear protein that stimulates proteasomal hydrolysis of peptides. [from NCI]

Hepatocellular carcinoma

Hepatocellular carcinoma is the major histologic type of malignant primary liver neoplasm. It is the fifth most common cancer and the third most common cause of death from cancer worldwide. The major risk factors for HCC are chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, prolonged dietary aflatoxin exposure, alcoholic cirrhosis, and cirrhosis due to other causes. Hepatoblastomas comprise 1 to 2% of all malignant neoplasms of childhood, most often occurring in children under 3 years of age. Hepatoblastomas are thought to be derived from undifferentiated hepatocytes (Taniguchi et al., 2002). [from OMIM]

Peptide Biosynthesis

The chemical reactions and pathways resulting in the formation of peptides, compounds of 2 or more (but usually less than 100) amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another. This may include the translation of a precursor protein and its subsequent processing into a functional peptide. [CHEBI:16670, GOC:dph, GOC:jl] [from GO]

Protein Modification, Translational

Any of the enzymatically catalyzed modifications of the individual AMINO ACIDS of PROTEINS, and enzymatic cleavage or crosslinking of peptide chains that occur pre-translationally (on the amino acid component of AMINO ACYL TRNA), co-translationally (during the process of GENETIC TRANSLATION), or after translation is completed (POST-TRANSLATIONAL PROTEIN PROCESSING). [from MeSH]

MedGen UID:

Concept ID:
C1449566
Molecular Function

Genetic translation

ribosome mediated process by which polypeptide chains are synthesized, the aminoacid sequence being completely determined by the sequence of bases in a messenger RNA, which in turn is determined by the sequences of bases in the DNA of the gene from which it was transcribed. [from CRISP]

Carbohydrate Metabolism

Cellular processes in biosynthesis (anabolism) and degradation (catabolism) of CARBOHYDRATES. [from MeSH]

Concept ID:
C0302820
Molecular Function

Protein Processing, Post-Translational

Any of various enzymatically catalyzed post-translational modifications of PEPTIDES or PROTEINS in the cell of origin. These modifications include carboxylation; HYDROXYLATION; ACETYLATION; PHOSPHORYLATION; METHYLATION; GLYCOSYLATION; ubiquitination; oxidation; proteolysis; and crosslinking and result in changes in molecular weight and electrophoretic motility. [from MeSH]
