IGF Axis & MusclePreclinical

IGF-1 DES, or des(1-3)-insulin-like growth factor 1, is a truncated analogue of IGF-1 that has reduced affinity for insulin-like growth factor binding proteins (IGFBPs) and is derived from the insulin-like growth factor family. Researchers primarily study IGF-1 DES to understand its effects on cellular growth, differentiation, and its potential role in various pathological conditions, including cancer and neuroprotection. Key findings indicate that while IGF-1 effectively reduces neuronal loss after hypoxic-ischemic brain injury, IGF-1 DES does not exhibit the same protective effects, suggesting a critical role for IGFBPs in mediating IGF-1's neuroprotective actions. Additionally, studies have shown that IGF-1 DES can induce hyperplastic growth in prostate epithelial cells without progressing to cancer, highlighting its complex biological behavior. Current research continues to explore the diverse effects of IGF-1 DES and its potential implications in both therapeutic and pathological contexts.

Poor bioavailability

IGF-1 DES is rapidly degraded in the bloodstream, limiting its half-life.

Mechanism

Mechanism of Action

Des-IGF-1, an analogue of IGF-1 with a reduced affinity for IGF binding proteins (IGFBPs), primarily activates the insulin receptor (IR) and the IGF-1 receptor (IGF-1R), leading to the activation of downstream signaling pathways such as the PI3K/Akt and MAPK/ERK pathways. This results in enhanced protein synthesis and inhibition of protein degradation, promoting cellular growth and survival. However, the precise mechanisms by which des-IGF-1 exerts its effects, particularly in the context of its interactions with IGFBPs and potential receptor cross-talk, remain incompletely understood.

Interactions of IGF-1 with the blood-brain barrier in vivo and in situ.

Pan W & Kastin A J · Neuroendocrinology · 2000

HumanInfluence6.0

154

Researchers studied how insulin-like growth factor-1 (IGF-1) crosses the blood-brain barrier (BBB) and its behavior in the brain and spinal cord. They found that IGF-1 can enter the brain quickly and remains intact for a short period, suggesting a specific transport system at the BBB that regulates its availability to the central nervous system.

Key findings

01Researchers observed that IGF-1 has a half-life of 4.5 minutes in blood and can enter the brain and spinal cord effectively after intravenous injection.
02The influx rate of IGF-1 into the brain was measured at 0.4 microl/g x min, indicating a significant transport mechanism.
03The study found that the presence of nonradiolabeled IGF-1 enhances the influx of IGF-1 into the brain when injected, but not during direct brain perfusion.

The effects of insulin-like growth factor (IGF)-1, IGF-2, and des-IGF-1 on neuronal loss after hypoxic-ischemic brain injury in adult rats: evidence for a role for IGF binding proteins.

Guan J, et al. · Endocrinology · 1996

AnimalInfluence8.0

Researchers observed that central administration of IGF-1 significantly reduced neuronal loss in adult rats after hypoxic-ischemic injury, while des-IGF-1 did not demonstrate similar protective effects.

Key findings

01IGF-1 significantly reduced neuronal loss in various brain regions after injury.
02IGF-2 was found to increase neuronal loss in certain areas of the brain.
03The presence of IGF binding proteins may influence the protective effects of IGF-1.

Insulin-like growth factor (IGF)-binding proteins inhibit the biological activities of IGF-1 and IGF-2 but not des-(1-3)-IGF-1.

Ross M, et al. · The Biochemical journal · 1989

In VitroInfluence2.0

133

Researchers studied how certain proteins, known as IGF-binding proteins, affect the actions of insulin-like growth factors IGF-1 and IGF-2. They found that these binding proteins can inhibit the growth-promoting effects of IGF-1 and IGF-2 but do not affect a variant called des-(1-3)-IGF-1.

Key findings

01Researchers found that a binding protein from bovine kidney significantly reduced the ability of IGF-2 to stimulate cell growth and protein production.
02The study observed that des-(1-3)-IGF-1 was not influenced by the binding proteins, indicating it remains more active than IGF-1 and IGF-2.
03Researchers noted that the effectiveness of IGF-1 and IGF-2 is inversely related to their binding to these proteins, suggesting that less binding leads to greater biological activity.

Functional characterization of des-IGF-1 action at excitatory synapses in the CA1 region of rat hippocampus.

Ramsey Melinda M, et al. · Journal of neurophysiology · 2005

AnimalInfluence5.0

Researchers studied the effects of a specific form of insulin-like growth factor-1 (des-IGF-1) on brain function in young rats. They found that des-IGF-1 significantly increased synaptic transmission in a brain region important for learning and memory, suggesting it may play a role in cognitive improvements.

Key findings

01Researchers observed a 40% increase in synaptic transmission in the hippocampus after applying des-IGF-1.
02The enhancement in synaptic activity was linked to a specific type of receptor (AMPA) and involved certain cellular signaling pathways.
03These findings may help explain how long-term increases in IGF-1 levels can benefit cognitive function in older animals.

Vitamin D and benign prostatic hyperplasia -- a review.

Espinosa Geovanni, et al. · The Canadian journal of urology · 2013

ReviewInfluence1.0

Researchers reviewed studies on the relationship between vitamin D and benign prostatic hyperplasia (BPH), a common condition affecting older men. They observed that higher vitamin D levels may be linked to a reduced prevalence of BPH and a decrease in prostate size.

Key findings

01Researchers found that vitamin D may inhibit certain pathways involved in prostate cell growth, potentially reducing BPH symptoms.
02The review indicated that increased vitamin D intake is associated with a lower prevalence of BPH among men.
03No negative side effects were reported from higher vitamin D intake in the studies reviewed.

Insulin-like growth factor (IGF) binding protein-3 inhibits type 1 IGF receptor activation independently of its IGF binding affinity.

Ricort J M & Binoux M · Endocrinology · 2001

In VitroInfluence2.0

Researchers found that a protein called IGFBP-3 can inhibit the activation of a specific receptor involved in cell signaling, known as the type 1 IGF receptor, without directly binding to it. This study highlights a unique regulatory mechanism that IGFBP-3 employs, which does not affect other related receptors, such as the insulin receptor.

Key findings

01IGFBP-3 significantly reduces the activation of the type 1 IGF receptor in breast cancer cells.
02The inhibitory effect of IGFBP-3 is specific to the IGF receptor and does not impact the insulin receptor.
03IGFBP-3's ability to modulate IGF signaling occurs independently of its binding to IGF.

Enforced epithelial expression of IGF-1 causes hyperplastic prostate growth while negative selection is requisite for spontaneous metastogenesis.

Kaplan-Lefko P J, et al. · Oncogene · 2008

AnimalInfluence1.0

The study demonstrated that enforced expression of IGF-1(des) in transgenic mice resulted in hyperplastic prostate growth but delayed the progression of tumors and metastasis.

Key findings

01Increased IGF-1 caused abnormal growth in prostate cells but did not lead to cancer within a year.
02Crossbreeding with a prostate cancer model delayed tumor progression and spread in younger mice.
03Older mice showed widespread metastasis, but the specific IGF-1 variant was not found in advanced tumors.
