| epidermal growth factor receptor (EGFR) | Epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein and member of the receptor tyrosine kinase family. It is encoded by the EGFR gene and is involved in the regulation of cell growth, survival, proliferation, and differentiation. Upon binding of its ligands, such as epidermal growth factor (EGF) or transforming growth factor-alpha (TGF-α), EGFR undergoes dimerization and autophosphorylation of its intracellular tyrosine kinase domain. This activation triggers multiple downstream signaling pathways, including the RAS-RAF-MEK-ERK and PI3K-AKT pathways, which mediate cellular responses such as gene expression, cell cycle progression, and inhibition of apoptosis. | EGFR is used as a biomarker in several clinical contexts, particularly in oncology. Its overexpression, gene amplification, or specific mutations have been observed in various cancers, including non-small cell lung cancer (NSCLC), colorectal cancer, and glioblastoma. In NSCLC, the presence of activating mutations in the EGFR gene can inform the use of targeted therapies, such as tyrosine kinase inhibitors. EGFR status may also be assessed to predict response to anti-EGFR monoclonal antibodies in colorectal cancer. Additionally, EGFR expression or mutation analysis can provide prognostic or predictive information in certain tumor types. |
| erb-b2 receptor tyrosine kinase 2 (ERBB2) | ERBB2, also known as HER2 (human epidermal growth factor receptor 2), encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This transmembrane protein lacks a known ligand but can form heterodimers with other EGFR family members, leading to activation of intracellular signaling pathways such as the MAPK and PI3K/AKT pathways. These signaling cascades regulate cell proliferation, differentiation, and survival. Overexpression or amplification of ERBB2 can result in enhanced signaling activity, contributing to uncontrolled cell growth and oncogenesis. | ERBB2 is used as a biomarker in several types of cancer, most notably breast cancer. Its gene amplification or protein overexpression is assessed to assist in diagnosis, prognosis, and to guide therapeutic decisions. Specifically, ERBB2 status can inform the use of targeted therapies, such as monoclonal antibodies and tyrosine kinase inhibitors, which are designed to inhibit ERBB2-mediated signaling. Assessment of ERBB2 is also relevant in other malignancies, including gastric and gastroesophageal junction cancers. |
| fibroblast growth factor receptor 3 (FGFR3) | Fibroblast growth factor receptor 3 (FGFR3) is a transmembrane receptor tyrosine kinase that belongs to the FGFR family. It is activated by binding to specific fibroblast growth factors (FGFs), leading to receptor dimerization and autophosphorylation. This activation initiates downstream signaling cascades, including the MAPK, PI3K/AKT, and STAT pathways, which regulate cell proliferation, differentiation, migration, and survival. FGFR3 plays a critical role in skeletal development, particularly in the regulation of chondrocyte proliferation and differentiation during bone growth. Mutations in FGFR3 are associated with various skeletal dysplasias, such as achondroplasia and thanatophoric dysplasia, and have been implicated in several cancers. | FGFR3 is used as a biomarker in multiple clinical contexts. In urothelial carcinoma, particularly non-muscle invasive bladder cancer, FGFR3 mutations and overexpression are frequently observed and are associated with certain tumor subtypes. Detection of FGFR3 alterations can aid in tumor classification, risk stratification, and may inform therapeutic decisions, including the selection of patients for FGFR-targeted therapies. FGFR3 status is also investigated in other malignancies, such as multiple myeloma and cervical cancer, where its alterations may have diagnostic, prognostic, or predictive significance. |
| marker of proliferation Ki-67 (MKI67) | The marker of proliferation Ki-67 (MKI67) gene encodes a nuclear protein that is associated with cellular proliferation. Ki-67 is present during all active phases of the cell cycle (G1, S, G2, and mitosis), but is absent from resting cells (G0 phase). The protein is involved in the organization of the perichromosomal layer during mitosis and plays a role in ribosomal RNA transcription. Its expression is tightly linked to cell division, making it a useful indicator of proliferative activity in tissues. | Ki-67 is widely used as a proliferation marker in histopathology, particularly in oncology. Its expression level, typically assessed by immunohistochemistry, provides an estimate of the growth fraction of a given cell population. Ki-67 labeling index is utilized in the assessment of tumor aggressiveness, prognosis, and, in some settings, to help guide treatment decisions, especially in cancers such as breast cancer, lymphoma, and neuroendocrine tumors. |
| microRNA 21 (MIR21) | microRNA 21 (MIR21) is a small non-coding RNA molecule that regulates gene expression post-transcriptionally. It primarily functions by binding to the 3'-untranslated regions (3'-UTRs) of target messenger RNAs (mRNAs), leading to mRNA degradation or inhibition of translation. MIR21 is involved in the regulation of various cellular processes, including cell proliferation, apoptosis, differentiation, and migration. It exerts its effects by modulating pathways such as the PTEN/PI3K/AKT, TGF-β, and MAPK signaling cascades. MIR21 is widely expressed in multiple tissues and is notably upregulated in response to cellular stress and injury. | MIR21 has been studied as a biomarker in a range of pathological conditions, most notably in cancer. Elevated levels of MIR21 have been detected in tumor tissues, blood, and other body fluids of patients with various malignancies, including breast, lung, colorectal, and gastric cancers. Its expression levels have been associated with disease presence, progression, and prognosis. Additionally, MIR21 has been investigated as a potential biomarker in non-malignant diseases such as cardiovascular and fibrotic disorders, where its altered expression correlates with disease states or outcomes. |
| telomerase reverse transcriptase (TERT) | Telomerase reverse transcriptase (TERT) is the catalytic subunit of the telomerase enzyme complex. TERT, together with the telomerase RNA component (TERC), is responsible for the addition of telomeric repeats (TTAGGG) to the ends of chromosomes during DNA replication. This process counteracts telomere shortening that naturally occurs with each cell division, thereby contributing to chromosomal stability and cellular replicative capacity. In most somatic cells, TERT expression is low or absent, leading to progressive telomere shortening and eventual cellular senescence. In contrast, TERT is highly expressed in germ cells, stem cells, and the majority of cancer cells, supporting sustained proliferative potential. | TERT has been studied as a biomarker in various contexts, particularly in oncology. Mutations in the TERT promoter region and increased TERT expression have been detected in multiple cancer types, including bladder, thyroid, and glioblastoma, among others. These alterations are associated with telomerase activation and cellular immortality, which are hallmarks of malignancy. Detection of TERT promoter mutations or elevated TERT mRNA levels in tumor tissue or bodily fluids can aid in cancer diagnosis, prognosis, and, in some settings, monitoring of disease progression. |
| tumor protein p53 (TP53) | Tumor protein p53 (TP53) encodes a transcription factor that plays a central role in regulating cell cycle progression, DNA repair, apoptosis, and senescence. Upon cellular stress or DNA damage, p53 is stabilized and activates the transcription of target genes involved in cell cycle arrest, allowing time for DNA repair or triggering programmed cell death if the damage is irreparable. TP53 is often referred to as the 'guardian of the genome' due to its critical function in maintaining genomic integrity and preventing the propagation of cells with genomic abnormalities. | TP53 is widely studied as a biomarker in oncology. Mutations in TP53 are among the most common genetic alterations observed in a variety of human cancers. The presence, type, and frequency of TP53 mutations in tumor tissue can provide information about tumorigenesis, prognosis, and potential therapeutic responses. Immunohistochemical detection of p53 protein accumulation is also used in diagnostic pathology to assess tumor characteristics. Additionally, TP53 mutation status is utilized in stratifying patients in clinical studies and may inform risk assessment and treatment strategies in certain cancer types. |
