Biochem/physiol Actions

Insulin-like growth factor II (IGF-II) also known as multiplication stimulating activity (MSA), shows virtually identical bioactivities as IGF-I. Expression of IGF-II is highest in fetal tissues, where it is believed to play a major role in overall growth and development. After birth IGF-II expression decreases to much lower levels in a variety of tissues. IGF-II is produced also in several tumors. IGF-II binds to IGF-II receptor (IGF-IIR), to IGF-IR and weakly to the insulin receptor (IR). All IGF-II bioactivities in adult tissues are generally attributed to its interaction with IGF-IR. However, during embryogenesis the roles of both IGF-IIR and IR may be significant in promoting normal growth.

Physical form

Lyophilized from a 0.2 μm filtered solution with no additives.

Analysis Note

The biological activity is measured by a cell proliferation assay using mouse FDC-P1

Insulin-like growth factors (IGFs) regulate diverse processes including energy metabolism, cell proliferation and embryonic development. They activate the IGF signaling pathway via binding to cell surface receptors. Here we report an essential role of IGF2 in maintaining the pluripotency of

Ewing sarcomas (ESs) are aggressive sarcomas driven by EWS fusion genes. We sought to investigate whether whole-transcriptome sequencing (RNA-seq) could be used to detect patterns associated with chemotherapy response or tumor progression after first-line treatment.
