Arabinogalactan, also known as galactoarabinan, larch arabinogalactan, and larch gum, is a biopolymer consisting of arabinose and galactose monosaccharides. Two classes of arabinogalactans are found in nature: plant arabinogalactan and microbial arabinogalactan. In plants, it is a major component of many gums, including gum arabic and gum ghatti.
Arabinogalactan-proteins (AGPs) are highly glycosylated proteins (glycoproteins) found in the cell walls of plants. Each one consists of a protein with sugar molecules attached (which can account for more than 90% of the total mass). They are members of the wider class of hydroxyproline (Hyp)-rich cell wall glycoproteins, a large and diverse ...
Because fungal and human cells are similar at a biochemical level it is often the case that chemical compounds intended for plant defence have an inhibitory effect on human cells, including human cancer cells. [4] Those plant chemicals that are selectively more toxic to cancer cells than normal cells have been discovered in screening programs ...
Hemicellulose dominates the middle lamella of the plant cell, unlike cellulose which is primarily found in the secondary layers. This allows for hemicellulose to provide middle-ground support for the cellulose on the outer layers of the plant cell.
Myb genes are part of a large gene family of transcription factors found in animals and plants. In humans, it includes Myb proto-oncogene like 1 and Myb-related protein B in addition to MYB proper. [5] [6] Members of the extended SANT/Myb family also include the SANT domain and other similar all-helical homeobox-like domains.
One of the earliest associations of human disease caused by Agrobacterium radiobacter was reported by Dr. J. R. Cain in Scotland (1988). [16] A later study suggested that Agrobacterium attaches to and genetically transforms several types of human cells by integrating its T-DNA into the human cell genome. The study was conducted using cultured ...

In breast cancer cells, it is hypothesised that galectin-3 has high affinity for cancer-associated MUC-1, causing depolarisation and breaking the cell's protective shield. This exposes small adhesion molecules on the surface of the cell, which interact with adhesion proteins on endothelial cell walls, such as E-selectin , promoting intravastion ...
