Deoxyhypusine Synthase Inhibitor, GC7, The Deoxyhypusine Synthase Inhibitor, GC7, also referenced under CAS 150333-69-0, controls the biological activity of Deoxyhypusine Synthase.
A cell-permeable inhibitor that targets the spermidine-binding site of Deoxyhypusine Synthase (Ki = 9.7 nM), an enzyme which is responsible for the first step hypunisation of eukaryotic initiation factor 5A (eIF5A). In vivo, it demonstrates almost complete cessation of hypusine formation in CHO cells at ≥ 1 µM. Several studies indicate this compound as a useful tool for the down-regulation of eIF5A, a protein essential for cell proliferation. For example, it exhibits an anti-proliferative effect on both BCR-ABL -positive and -negative leukemia cell lines (K562 and HL-60) dose-dependently, at concentrations between 5 µM and 40 µM. In addition, it is shown to significantly impair the growth and invasion of primary HCC cells (HepG2 and Hep3B) in the 10-20 µM range, and against non-tumorigenic CL-48 cells at concentrations as high as 40 µM, with no apparent cytotoxicity. At 25 µM, GC7 treatment is shown to reverse eIF5a-mediated Skeletal Muscle Stem Cell Differentiation.

Phagocytosis, the process by which cells engulf large particles, plays a vital role in driving tissue clearance and host defense. Its dysregulation is connected to autoimmunity, toxic accumulation of proteins, and increased risks for infections. Despite its importance, we lack
Journal of ovarian research, 14(1), 140-140 (2021-10-24)
Poly (ADP)-ribose polymerase (PARP) inhibitors have entered routine clinical practice for the treatment of high-grade serous ovarian cancer (HGSOC), yet the molecular mechanisms underlying treatment response to PARP1 inhibition (PARP1i) are not fully understood. Here, we used unbiased mass spectrometry
Frontiers in cellular and infection microbiology, 12, 960138-960138 (2022-08-16)
Active hypusine-modified initiation elongation factor 5A is critical for cell proliferation and differentiation, embryonic development, and innate immune response of macrophages to bacterial infection. Here, we demonstrate that both virus infection and double-stranded RNA viral mimic stimulation induce the hypusination
Polyamines are critical metabolites involved in various cellular processes and often dysregulated in cancers. Kaposi's sarcoma-associated Herpesvirus (KSHV), a defined human oncogenic virus, leads to profound alterations of host metabolic landscape to favor development of KSHV-associated malignancies. In our studies
Vaccines are powerful tools to develop immune memory to infectious diseases and prevent excess mortality. In older adults, however vaccines are generally less efficacious and the molecular mechanisms that underpin this remain largely unknown. Autophagy, a process known to prevent
