Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

β‐Galactosidase decreases the binding affinity of the insulin‐like‐growth‐factor‐II/mannose‐6‐phosphate receptor for insulin‐like‐growth‐factor II [PDF]
The insulin‐like growth‐factor‐II/mannose‐6‐phosphate (IGF‐II/Man6P) receptor binds two classes of ligands, insulin‐like growth factors and lysosomal enzymes. We have examined the ability of the lysosomal enzyme, β‐galactosidase, to modulate the binding of 125I‐IGF‐II to the receptor.

MITF maintains genome stability in nonmelanocyte lineages
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

IGF-I receptor phosphorylation is impaired in cathepsin X-deficient prostate cancer cells [PDF]
The cysteine-type peptidase cathepsin X is highly upregulated in several cancers and presumably promotes tumor invasion through bypassing cellular senescence. Here, we present first evidence that the underlying mechanism may involve the regulation of the

Retroperitoneal Doege–Potter syndrome with intraoperative blood glucose monitoring
Background Doege–Potter syndrome, characterized by solitary fibrous tumors and non‐islet cell tumor hypoglycemia, is rare. Here, we report a case of Doege–Potter syndrome in which retroperitoneal tumor resection was performed with continuous ...

Metabolic actions of insulin-like growth factor II in cultured adult rat hepatocytes are not mediated through the insulin-like growth factor II receptor [PDF]
Short- and long-term regulation of hepatic carbohydrate metabolism by insulin-like growth factor II was studied in primary cultures of adult rat hepatocytes and compared to the metabolic potency of insulin. Insulin-like growth factor II stimulated glycogen synthesis from [14C]glucose, uptake of [3H]aminoisobutyric acid and [14C]lactate formation from ...

The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Role of insulin-like growth factor binding protein-3 in 1, 25-dihydroxyvitamin-d 3 -induced breast cancer cell apoptosis. [PDF]
Insulin-like growth factor I (IGF-I) is implicated in breast cancer development and 1, 25-dihydroxyvitamin D3 (1, 25-D3) has been shown to attenuate prosurvival effects of IGF-I on breast cancer cells.

Effects of Insulin-Like Growth Factor (IGF-1) in Patients with Sensorineural Hearing Loss
OBJECTIVES: (1) To test the effect of local administration of insulin-like growth factor-1 (IGF-1) in patients with sensorineural hearing loss (SNHL). (2) To test the effect of local administration of IGF-1 in patients with ototoxicity.

Endocytosis of Insulin-like Growth Factor II by a Mini-receptor Based on Repeat 11 of the Mannose 6-Phosphate/Insulin-like Growth Factor II Receptor [PDF]
The mannose 6-phosphate/insulin-like growth factor II receptor (M6P/IGF-II receptor) plays an important role in controlling the extracellular level of the insulin-like growth factor II (IGF-II) by mediating its binding at the cell surface and delivery to lysosomes.
