Curcumin causes DNA damage and affects associated protein expression in HeLa human cervical cancer cells.

Cervical cancer is one of the most common cancers in women worldwide and it is a prominent cause of cancer mortality. Curcumin is one of the major compounds from Turmeric and has been shown to induce cytotoxic cell death in human cervical cancer cells. However, there is no study to show curcumin induced DNA damage action via the effect on the DNA damage and repair protein in cervical cancer cells in detail.

Different effects on triacylglycerol packaging to oil bodies in transgenic rice seeds by specifically eliminating one of their two oleosin isoforms.

Expression of OLE16 and OLE18, two oleosin isoforms in oil bodies of rice seeds, was suppressed by RNA interference. Electron microscopy revealed a few large, irregular oil clusters in 35S::ole16i transgenic seed cells, whereas accumulated oil bodies in 35S::ole18i transgenic seed cells were comparable to or slightly larger than those in wild-type seed cells. Large and irregular oil clusters were observed in cells of double mutant seeds.
