| Gene Target | Biological Function | Application as a Biomarker |
|---|---|---|
| B-Raf proto-oncogene, serine/threonine kinase (BRAF) | The B-Raf proto-oncogene, serine/threonine kinase (BRAF), encodes a cytoplasmic serine/threonine protein kinase that is a member of the RAF kinase family. BRAF plays a central role in the RAS-RAF-MEK-ERK signaling pathway (also known as the MAPK/ERK pathway), which transmits signals from cell surface receptors to the nucleus. This pathway regulates key cellular processes, including cell division, differentiation, and survival. Upon activation by RAS proteins, BRAF phosphorylates and activates MEK1/2, which in turn phosphorylate ERK1/2, leading to the regulation of gene expression. Mutations in BRAF, particularly the V600E substitution, result in constitutive kinase activation and have been implicated in oncogenesis. | BRAF is widely used as a molecular biomarker in oncology. The presence of specific BRAF mutations, most notably the V600E mutation, is used to aid in the diagnosis, prognosis, and therapeutic stratification of various cancers, including melanoma, colorectal cancer, papillary thyroid carcinoma, and non-small cell lung cancer. Detection of BRAF mutations can inform the selection of targeted therapies, such as BRAF inhibitors, and may provide information on disease progression and potential resistance mechanisms. |
| C-X-C motif chemokine receptor 4 (CXCR4) | C-X-C motif chemokine receptor 4 (CXCR4) is a G protein-coupled receptor that primarily binds to the chemokine CXCL12 (also known as stromal cell-derived factor-1, SDF-1). CXCR4 plays a critical role in the regulation of hematopoietic cell trafficking, immune cell migration, and organ development. It is essential for embryogenesis, particularly in the formation of the cardiovascular, hematopoietic, and nervous systems. In the immune system, CXCR4 mediates the homing and retention of hematopoietic stem cells in the bone marrow and guides the migration of lymphocytes and other immune cells to sites of inflammation or injury. Additionally, CXCR4 is involved in HIV-1 infection as a coreceptor that facilitates viral entry into target cells. | CXCR4 expression has been studied as a biomarker in various clinical contexts, particularly in oncology. Elevated CXCR4 levels have been observed in multiple types of cancer, including breast, lung, colorectal, and hematological malignancies, and have been associated with tumor aggressiveness, metastatic potential, and prognosis. In hematological diseases such as acute myeloid leukemia (AML), CXCR4 expression has been evaluated for its association with disease progression and response to therapy. Furthermore, CXCR4 is used to identify specific cell populations, such as hematopoietic stem and progenitor cells, in research and clinical settings. |
| KRAS proto-oncogene, GTPase (KRAS) | KRAS (Kirsten rat sarcoma viral oncogene homolog) encodes a small GTPase that is part of the RAS family of proteins. KRAS functions as a molecular switch in signal transduction pathways, cycling between an active GTP-bound state and an inactive GDP-bound state. When activated, KRAS transmits signals from cell surface receptors, such as receptor tyrosine kinases, to downstream effectors including the RAF-MEK-ERK and PI3K-AKT pathways. These signaling cascades regulate key cellular processes such as proliferation, differentiation, and survival. Mutations in KRAS can result in constitutive activation of the protein, leading to uncontrolled cell growth and oncogenesis. | KRAS is widely utilized as a biomarker in oncology, particularly in the context of solid tumors such as colorectal, lung, and pancreatic cancers. Detection of KRAS mutations in tumor tissue is used to inform prognosis and guide therapeutic decisions. For example, the presence of activating KRAS mutations in colorectal cancer is associated with lack of response to anti-EGFR monoclonal antibody therapies. Additionally, KRAS mutation status may be used to stratify patients for clinical trials and to monitor disease progression or recurrence through molecular assays. |
| MYC proto-oncogene, bHLH transcription factor (MYC) | The MYC proto-oncogene, bHLH transcription factor (MYC), encodes a nuclear phosphoprotein that functions as a transcription factor. MYC regulates the expression of a broad array of genes involved in cell cycle progression, cellular growth, apoptosis, metabolism, and differentiation. It forms heterodimers with the MAX protein, binding to E-box sequences in DNA to activate or repress target gene transcription. MYC activity is tightly regulated under normal physiological conditions, but its dysregulation—often through gene amplification or translocation—can lead to uncontrolled cell proliferation and oncogenesis. | MYC is commonly assessed as a biomarker in various cancers, including Burkitt lymphoma, diffuse large B-cell lymphoma, and several solid tumors. Its overexpression, gene amplification, or chromosomal rearrangements are associated with aggressive disease phenotypes and can provide prognostic information. Detection of MYC status may aid in disease classification, risk stratification, and therapeutic decision-making in oncology. |
| TNF receptor superfamily member 17 (TNFRSF17) | TNF receptor superfamily member 17 (TNFRSF17), also known as B-cell maturation antigen (BCMA), is a cell surface receptor primarily expressed on mature B lymphocytes and plasma cells. TNFRSF17 binds to the ligands B-cell activating factor (BAFF, also known as TNFSF13B) and a proliferation-inducing ligand (APRIL, TNFSF13), both members of the tumor necrosis factor (TNF) ligand family. Engagement of TNFRSF17 by these ligands promotes B cell survival, differentiation, and antibody production by activating downstream signaling pathways such as NF-κB and MAPK. TNFRSF17 plays a critical role in the maintenance of long-lived plasma cells and humoral immunity. | TNFRSF17 is utilized as a biomarker for the identification and quantification of plasma cells in hematological samples. Its elevated expression is associated with certain B cell malignancies, particularly multiple myeloma, where it serves as a marker for malignant plasma cells in bone marrow and peripheral blood. Measurement of TNFRSF17 expression can aid in the diagnosis, monitoring of disease progression, and assessment of minimal residual disease in multiple myeloma and related disorders. |
| cyclin D1 (CCND1) | Cyclin D1, encoded by the CCND1 gene, is a regulatory protein that plays a critical role in cell cycle progression. It functions as a component of the cyclin D1-CDK4/6 holoenzyme complex, which phosphorylates the retinoblastoma protein (RB1), thereby promoting the transition from the G1 to S phase of the cell cycle. This regulation is essential for controlled cell proliferation. Cyclin D1 expression is tightly regulated by mitogenic signals, and its dysregulation can lead to aberrant cell cycle progression and has been implicated in oncogenesis. | Cyclin D1 is commonly assessed as a biomarker in various cancers, including breast cancer, mantle cell lymphoma, and head and neck squamous cell carcinoma. Overexpression or gene amplification of CCND1 can be detected by immunohistochemistry or molecular techniques, and is associated with certain tumor subtypes and clinicopathologic features. Its evaluation may aid in tumor classification, prognostication, and, in some contexts, may inform therapeutic decision-making. |
| 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 binds to specific fibroblast growth factors (FGFs), leading to receptor dimerization and autophosphorylation of intracellular tyrosine residues. This activation initiates downstream signaling cascades, including the RAS-MAPK, PI3K-AKT, and STAT pathways, which regulate cellular processes such as proliferation, differentiation, and apoptosis. FGFR3 plays a critical role in skeletal development by modulating chondrocyte proliferation and differentiation, and it is also involved in tissue homeostasis and repair in several organ systems. | FGFR3 is used as a biomarker in various cancers, most notably urothelial carcinoma of the bladder. Somatic mutations and gene fusions involving FGFR3 have been detected in a significant subset of non-muscle-invasive bladder cancers and are associated with specific tumor subtypes. Detection of FGFR3 alterations can aid in the molecular classification of tumors, inform prognosis, and identify patients who may benefit from targeted therapies directed against FGFR3. FGFR3 mutations are also evaluated in other malignancies, such as cervical and lung cancers, to support diagnostic and therapeutic decision-making. |
| interleukin 6 (IL6) | Interleukin 6 (IL6) is a multifunctional cytokine produced by a variety of cell types, including T cells, B cells, macrophages, fibroblasts, endothelial cells, and others. IL6 plays a central role in the regulation of immune responses, inflammation, hematopoiesis, and the acute-phase response. It mediates its effects by binding to the IL6 receptor (IL6R) and subsequently activating the JAK/STAT signaling pathway. IL6 stimulates the differentiation of B cells into antibody-producing cells, promotes T cell proliferation, and influences the production of acute-phase proteins by hepatocytes. In addition to its immunomodulatory roles, IL6 is involved in metabolic regulation, bone homeostasis, and the response to tissue injury. | IL6 is frequently measured as a biomarker of inflammation and immune activation. Elevated levels of IL6 in blood or other biological fluids have been associated with various pathological conditions, including infections, autoimmune diseases, chronic inflammatory disorders, and certain cancers. IL6 concentrations are commonly assessed to provide information on the presence and severity of systemic inflammation, to monitor disease progression, and to evaluate the response to therapy in clinical and research settings. |
| syndecan 1 (SDC1) | Syndecan 1 (SDC1) is a transmembrane heparan sulfate proteoglycan that plays key roles in cell-cell and cell-matrix interactions. It is expressed on the surface of epithelial cells and some immune cells. SDC1 participates in the regulation of cell proliferation, migration, and adhesion by interacting with growth factors, cytokines, and components of the extracellular matrix. Its heparan sulfate chains facilitate binding to various ligands, modulating signaling pathways involved in tissue repair, inflammation, and development. SDC1 can also be shed from the cell surface, releasing its ectodomain into the extracellular environment, where it may influence cellular communication and matrix remodeling. | SDC1 has been studied as a biomarker in several clinical contexts. Elevated levels of soluble SDC1 in blood or other body fluids have been associated with disease states such as multiple myeloma, where it reflects tumor burden and disease progression. Increased SDC1 expression or shedding has also been reported in various solid tumors, inflammatory conditions, and tissue injury, where it may correlate with disease severity or prognosis. Measurement of SDC1 levels can aid in disease monitoring and may provide information about pathological processes involving epithelial or endothelial cell activation and damage. |
| tumor protein p53 (TP53) | Tumor protein p53 (TP53) encodes a transcription factor that plays a central role in regulating the cell cycle, DNA repair, apoptosis, senescence, and genomic stability. Under conditions of cellular stress, such as DNA damage or oncogene activation, p53 is stabilized and activated, leading to the transcription of target genes involved in cell cycle arrest (e.g., CDKN1A/p21), DNA repair (e.g., GADD45), and apoptosis (e.g., BAX, PUMA). By promoting these processes, p53 acts as a critical tumor suppressor, preventing the propagation of cells with genomic abnormalities. Loss or mutation of TP53 impairs these protective mechanisms and is associated with increased susceptibility to malignant transformation. | TP53 is widely studied as a biomarker in oncology. Mutations in TP53 are among the most common genetic alterations observed in human cancers and are frequently associated with tumor development and progression. Detection of TP53 mutations or abnormal p53 protein expression can provide information relevant to diagnosis, prognosis, and potential therapeutic strategies in various cancers, including breast, lung, colorectal, and ovarian malignancies. In some settings, TP53 status is used to assess tumor aggressiveness or predict response to specific treatments. |
