Abstract

ABC and immunohistochemical methods were used to compare the location of 8 lectin receptors (LRS) and carcinoembryonic antigen (CEA) in 100 cancerous and 56 non-cancerous tissues of the human breast. The results showed that the positive rates of peanutagglutinin (PNA) in the normal breast tissues, benign lesions and breast cancers were 38.1%, 37.1% and 73.7%, respectively (P < 0.005). The positive rates of Bardeiraea simpoicifolia receptors (BSL) in these 3 tissues were 14.3%, 17.1% and 75% (P < 0.005). The positive rates of CEA in these 3 tissues were 42.86%, 51.43% and 78.13% (P < 0.005). Analysis of the differences among the positive rates in cancerous tissues, normal breast tissue and non-cancerous tissues showed that CEA was not superior to BSL or PNA in its specificity in detecting breast cancers. Comparing the location of LRSs in the CEA positive specimens, we had discovered obvious differences in BSL and WGA in cancerous and non-cancerous tissues of the human breast. This implies that there may be a subtype CEA which is highly specific for breast cancers.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
