Microtubule associated protein tau is a neuronal microtubule-associated protein found predominantly in brain. Abnormal phosphorylation of tau is involved in the pathogenesis of Alzheimer’s disease (AD). The tau protein phosphorylated at threonine 181 (p-tau181) is a promising diagnostic biomarker for AD.

Pregnancy-associated plasma protein A (PAPP-A) is a high molecular weight protein. htPAPP-A is a protein complex which comprises of two PAPP-A subunits and two proform of eosinophil major basic protein. It exists in the blood of pregnant woman. dPAPP-A is a htPAPP-A dimmer which is composed of two PAPP-A subunits. htPAPP-A serves as a useful marker for the diagnosis of Down syndrome (DS).

PCT, a 116 amino acid (aa) protein, is comprised of three sections including a 57 aa N-terminal PCT, a 32 aa calcitonin and a 21 aa katacalcin. Calcitonin is a hormone, derived from PCT cleavage. PCT is a good diagnosis marker for bacterial infection. Other diseases such as sepsis, inflammation, surgery, heat shock, burn injuries and cardiogenic shock can also cause an increase of PCT level in blood.

Programmed Cell Death Protein 1 (PD-1), is cell surface receptor expressing on T cells and pro-B cells. The binding of PD-1 to its two ligands, PD-L1 and PD-L2, could result in down-regulation of the immune system by inhibiting the T-cell activation process. Thus, PD-1 is an important immune checkpoint and a popular target for therapeutic antibodies against many cancers.

Pepsinogen are aspartic proteinases, which are classified into two groups: pepsinogen I (PGI) and pepsinogen II (PGII). PGI and PGII are mainly secreted by gastric chief cells. PGI and PGII are of useful aid in diagnosing severe atrophic gastritis and stomach cancer.

Protein Induced by Vitamin K Absence or Antagonist-II (PIVKA-II), also known as Des-γ-carboxy-prothrombin (DCP), is an abnormal form of prothrombin. Normally, the prothrombin’s 10 glutamic acid residues (Glu) in the γ-carboxyglutamic acid (Gla) domain at positions 6, 7, 14, 16, 19, 20,25, 26, 29 and 32 are γ-carboxylated to Gla by vitamin-K dependent γ- glutamyl carboxylase in the liver and then secreted into plasma. In patients with hepatocellular carcinoma (HCC), γ-carboxylation of prothrombin is impaired so that PIVKA-II is formed instead of prothrombin. PIVKA-II is considered as is an efficient biomarker specific for HCC.

The
progesterone is a steroid hormone which is secreted by the female reproductive
systems. Its concentration is associated with the development and regression of
the corpus luteum. The progesterone is used in evaluation of ovulation status and
assessment of the luteal phase

Progastrin-releasing peptide (ProGRP) is a stable
precursor of the gastrin releasing peptid. It is composed of GRP (residues
1–27), a cleavage site (residues 28–30), and a constant region (residues 31–98).
ProGRP is a tumor marker for the diagnosis and monitoring of small cell lung
cancer (SCLC).
