Finding The Right Biomarker for Cancer Research

Cancer has a major impact on society around the world and biomarkers play a pivotal role in cancer research. Leinco technologies brings you numerous resources for validating biomarkers against different cancer types and stages, discovering new biomarkers to improve diagnostics and drug development, identifying the impact biomarkers have on disease progression, and more. Take a look at the following list of cancer types and associated antibodies and proteins reported in applications.

 

Programmed Death-1 (PD-1) & Programmed Death-1 Ligand (PD-L1)

PD-L1 is a transmembrane protein that interacts with PD-1 to suppress lymphocyte activation and function, promote regulatory T cell responses, and impair anti-tumor T cell immune responses. PD-L1 is upregulated in non-small cell lung cancer (NSCLC) and correlates to the degree of tumor cell differentiation and metastasis1, suggesting its potential as a prognostic biomarker. PD-L1 is also a predictive biomarker, and IHC assays measure levels on lung cancer tissue to determine responsiveness to checkpoint inhibitors that target PD-1 or PD-L1. Tumor-infiltrating CD8+ T cells have increased PD-1 expression in patients with NSCLC, associated with impaired immune function2.

Cytotoxic T-lymphocyte-associated Protein 4 (CTLA-4)

CTLA-4 is a checkpoint protein present on the surface of activated T cells that negatively regulates T cell proliferation and T cell-mediated immune responses. CTLA-4 is expressed in NSCLC but not normal bronchial tissues and has prognostic value1,2. CTLA-4 expression on tumor cells contributes to tumorigenesis by increasing PD-L1 expression and cancer cell proliferation via the EGFR pathway2. Although anti-CTLA-4 antibodies, such as ipilimumab, are not effective treatments for NSCLC on their own, combination treatment with PD-1/PD-L1 inhibitors shows promise in PD-L1 positive NSCLC patients3.

Vascular Endothelial Growth Factor (VEGF)

VEGF is a homodimeric glycoprotein that promotes angiogenesis in both physiological and pathological contexts, such as cancer1. VEGF contributes to lung cancer tumorigenesis through autocrine signaling, promoting epithelial-mesenchymal transition and invasiveness2. VEGF levels may be a useful diagnostic and prognostic biomarker for lung cancer, with relatively high sensitivity and specificity for NSCLC3.

FAS/CD95

Fas is a death receptor that induces apoptosis upon binding to Fas ligand (FasL) on cytotoxic T cells. Fas expression is decreased in lung tumor tissues, contributing to tumorigenesis by evading the immune system and apoptosis1. In contrast, FasL is overexpressed in small cell lung carcinoma and correlates with advanced tumor stage, and may promote paracrine killing of cytotoxic T cells in the absence of Fas expression on tumor cells1.

CD52

CD52 is a GPI-anchored glycoprotein that is expressed on hematopoietic cells, with highest expression on lymphocytes and neoplastic B cells1. Soluble CD52 is released from CLL cells and detected at high levels in the plasma of CLL patients, which is correlated with cancer stage2. High soluble CD52 levels predict progression following treatment with fludarabine, cyclophosphamide, and rituximab3. Similarly, high CD52 mRNA levels are associated with shorter survival following treatment with the anti-CD52 anbitody alemtuzumab4.

Interleukin 6 (IL-6)

Renal cell carcinoma cells secrete IL-6, an autocrine tumor growth factor that activates the JAK-STAT pathway1. Therefore, an increase in serum IL-6 levels is an independent prognostic factor for survival metastatic RCC patients2. IL-6 may also predict response to treatment with the tyrosine kinase inhibitor pazopanib3.

Vascular Endothelial Growth Factor (VEGF)

VEGF is a homodimeric glycoprotein that promotes angiogenesis in both physiological and pathological contexts, such as cancer1. Approximately 60% of clear cell renal cell carcinomas are associated with loss of function of the VHL gene, which induces hypoxia-inducible factors and enhanced transcription and expression of VEGF, promoting angiogenesis2. Higher VEGF levels are associated with worse prognosis3 and may predict response to VEGF pathway inhibitors, such as sorafenib4.

Tumor Necrosis Factor-related Apoptosis-inducing Ligand (TRAIL)

TRAIL is a cytokine that preferentially induces extrinsic apoptosis in cancer cells by binding to death receptors1. Serum levels of TRAIL are lower in renal cell carcinoma patients compared to healthy controls, identifying it as a potential diagnostic biomarker2. In addition, TRAIL may have prognostic value as serum TRAIL levels are lower in patients with metastasis and higher cancer stage2.

Epidermal Growth Factor Receptor (EGFR)

EGFR is a transmembrane glycoprotein belonging to the tyrosine kinase family and plays essential roles in cell proliferation, survival, differentiation, and migration. Overexpression of EGFR and mutations in its downstream mediators, such as Ras, are present in most pancreatic tumors1,2. EGFR overexpression is associated with higher mortality rates, extensive tumor growth, and metastasis3.

IgG4

IgG4 is the least common IgG antibody, typically accounting for 4% of serum IgG. However, elevated IgG4 serum levels are found in some patients with pancreatic cancer1. In addition, high infiltration of IgG4-positive plasma cells may be an independent predictor of poor overall survival in pancreatic cancer patients after curative resection2.

Osteopontin (OPN)

The extracellular matrix protein, OPN, is a signaling molecule with various functions, including cell adhesion and migration, inflammation, and apoptosis. OPN is thought to promote tumorigenesis and metastasis and increases the invasiveness of pancreatic cancer cells1. OPN is overexpressed in pancreatic cancer and has similar sensitivity and specificity as the standard biomarker assay for diagnosing pancreatic cancer2.

GDF-15/MIC-1

GDF-15 is a transforming growth factor β superfamily cytokine that inhibits macrophage activation1. GDF-15 serum levels are elevated in pancreatic cancer patients compared with healthy controls2, and serum GDF-15 levels have similar diagnostic accuracy as the standard assay for pancreatic cancer4. Elevated expression of MIC-1 is associated with an androgen-independent phenotype and poor outcomes for patients with pancreatic cancer3. Poorer outcomes may arise from the role of MIC-1 in cancer cell metastasis or proliferation4,5.

CD47/HNK-1

CD47 is a ubiquitously expressed surface protein that binds to the ligand SIRPα on macrophages, inhibiting phagocytosis of self cells1,2. Therefore, cancer cells can evade phagocyte-mediated immunity by upregulating CD47. Tumor cell expression of CD47 varies between different types of sarcoma, with high expression in chordoma and angiosarcoma1.

Survivin/BIRC5

Survivin is an inhibitor of apoptosis protein family member and suppresses apoptosis by binding to caspases-3, -7, and -91. Survivin is expressed in osteosarcoma tumors, with minimal expression in normal tissues, making it a promising diagnostic marker2. Survivin also has prognostic potential, as patients with metastatic osteosarcoma exhibit higher survivin levels at initial biopsy, and levels are higher in patients with metastases than those without3,4.

Matrix Metalloproteinases (MMPs)

MMPs degrade collagen of the extracellular matrix, contributing to tissue remodeling as well as tumor invasion and metastasis. Expression of MMPs, including MMP-9 and MMP-1, correlates with metastasis and poor prognosis in osteosarcoma. Consistent with the role of MMPs in metastasis, in vitro treatment with MMP inhibitors inhibits osteosarcoma tumor cell invasion1-4.

Galectin-3 (Gal-3)

Gal-3 binds to β-galactosidase on cell surface glycoproteins and regulates cell proliferation and apoptosis of normal and cancer cells. Gal-3 is strongly expressed by thyroid cancer tissues but not normal thyroid tissues and is reported in 90-100% of papillary thyroid carcinoma cases (PTC)1. Furthermore, Gal-3 expression correlates with tumor invasiveness and metastasis1; however, the prognostic abilities of Gal-3 are controversial and need further investigation.

Matrix Metalloproteinases (MMPs)

MMPs degrade collagen of the extracellular matrix, contributing to tissue remodeling as well as tumor invasion and metastasis. Serum levels of MMP-2 are higher in patients with PTC and differentiated thyroid carcinoma (DTC) compared to those with benign thyroid disease and healthy controls1,2, and high MMP-2 levels are an independent risk factor for metastasis and worse clinical outcomes1. MMP-9 is also higher and correlates with metastasis in DTC patients2.
