Several cervical, endometrial ovarian and liver cancers along with a few colorectal, prostate, lung and pancreatic cancers showed weak to moderate cytoplasmic positivity which often had a dot-like pattern. Cases of gliomas displayed moderate to strong staining. Remaining cancer cells were generally negative.
A majority of malignant cells displayed weak to moderate cytoplasmic staining.
GENE INFORMATION
Gene name
IL4R (HGNC Symbol)
Synonyms
CD124
Description
Interleukin 4 receptor (HGNC Symbol)
Entrez gene summary
This gene encodes the alpha chain of the interleukin-4 receptor, a type I transmembrane protein that can bind interleukin 4 and interleukin 13 to regulate IgE production. The encoded protein also can bind interleukin 4 to promote differentiation of Th2 cells. A soluble form of the encoded protein can be produced by proteolysis of the membrane-bound protein, and this soluble form can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells. Allelic variations in this gene have been associated with atopy, a condition that can manifest itself as allergic rhinitis, sinusitus, asthma, or eczema. Polymorphisms in this gene are also associated with resistance to human immunodeficiency virus type-1 infection. Alternate splicing results in multiple transcript variants.
