The causes of acquired resistance to synthesized molecules are various, for example, the acquisition of a new mutation in the molecular target (T790M EGFR) , masking the extracellular epitope of ErbB2 by hyaluronic acid , alternative pathways to support proliferation of the cancer cells (IGFR
expression) , or loss of one of the negative regulators of PI3K/Akt survival pathway (phosphatase and tensin homolog, PTEN) .
When r < [v.sub.L]/[v.sub.H]and G(x) are IGFR
distributions, the firm's optimal solution is given in the following situations.
Insulin receptors (IR) are also overexpressed in cancers and they form hybrid receptors that are a cross between IGFR
and IR so that both insulin and IGF-1 will activate them.
The IGFBP-1 is mainly synthesized in the liver, and lesser production of IGFBP-1 can ensure sufficient IGF-1 in circulation to bind to the IGFR
to respond to hypoxic stress in yak.

As with Hoxa-13, Fgf-10 and insulin-like growth factor receptor (Igfr
) knockout mice have been shown to develop hypospadias.

Given that insulin elicits its effect majorly by binding to the insulin receptor (IR) and/or insulin-like growth factor receptor (IGFR
) , it is possible that relatively low basal expression of IR and IGFR
in UCM-MSC might be why they are not responsive to insulin at physiologically relevant dosages.
