Lectin, galactoside-binding, soluble, 8

galectin-8, Gal-8, Po66-CBP, PCTA-1
This gene encodes a member of the galectin family. Galectins are beta-galactoside-binding animal lectins with conserved carbohydrate recognition domains. The galectins have been implicated in many essential functions including development, differentiation, cell-cell adhesion, cell-matrix interaction, growth regulation, apoptosis, and RNA splicing. This gene is widely expressed in tumoral tissues and seems to be involved in integrin-like cell interactions. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008] (from NCBI)

Comparison of galectin expression signatures in rejected and accepted murine corneal allografts.
Panjwani et al., Boston, United States. In Cornea, Jun 2015
Although in both accepted and rejected grafts, expression levels of the 5 lectins were upregulated compared with normal corneas, there were distinct differences in the expression levels of galectins-8 and 9 between accepted and rejected grafts, as both the Western blot and immunofluorescence staining revealed that galectin-8 is upregulated, whereas galectin-9 is downregulated in the rejected grafts compared with the accepted grafts.
Unraveling functional significance of natural variations of a human galectin by glycodendrimersomes with programmable glycan surface.

Alteration of the linker length in human galectin-8 and single-site mutation (F19Y) are used herein to illustrate the potential of glycodendrimersomes with programmable glycan displays as a model system to reveal the functional impact of natural sequence variations in trans recognition.
The mammalian lectin galectin-8 induces RANKL expression, osteoclastogenesis, and bone mass reduction in mice.
Zick et al., Israel. In Elife, 2014
In this study, we show that mice overexpressing galectin-8, a secreted mammalian lectin of the galectins family, exhibit accelerated osteoclasts activity and bone turnover, which culminates in reduced bone mass, similar to cases of postmenopausal osteoporosis and cancerous osteolysis.
