2,4-Dihydroxy-3'-methoxy-4'-ethoxychalcone suppresses cell proliferation and induces apoptosis of multiple myeloma the PI3K/akt/mTOR signaling pathway.

Kom. (Fabaceae), a commonly used folk medicine, has been found to possess antitumor effects. However, the antiproliferative effect of 2,4-dihydroxy-3'-methoxy-4'-ethoxychalcone (DMEC) derived from against multiple myeloma (MM) has never been investigated.

Adenovirus vector‑mediated in vivo gene transfer of nuclear factor erythroid‑2p45‑related factor 2 promotes functional recovery following spinal cord contusion.

The aim of the present study was to investigate whether nuclear factor erythroid 2p45‑related factor 2 (Nrf2) overexpression by gene transfer may protect neurons/glial cells and the association between neurons/glial cells and axons in spinal cord injury (SCI). In the present study, Nrf2 recombinant adenovirus (Ad) vectors were constructed. The protein levels of Nrf2 in the nucleus and of the Nrf2‑regulated gene products heme oxygenase‑1 (HO‑1) and NAD (P)H‑quinone oxidoreductase‑1 (NQO1), were detected using western blot analysis in PC12 cells following 48 h of transfection.

Lipopolysaccharide preconditioning attenuates apoptotic processes and improves neuropathologic changes after spinal cord injury in rats.

We have shown earlier that administration of low-dose lipopolysaccharide (LPS) significantly contributed to recovery of motor function after traumatic spinal cord injury in the adult female rat. Using the same standardized animal model, we have now designed a set of experiments to test the hypothesis that LPS preconditioning attenuates stress-related apoptotic processes early after spinal cord trauma. The lower thoracic spinal cord injury in adult female Sprague-Dawley rats was caused by a 10 g weight rod drop from 25 mm on the dural surface of the exposed spinal cord at T10.
