Following treatment with cytotoxic drugs, some cancer cells use the Chk1 pathway to increase cell survival by pausing DNA replication and allowing repair of the damaged DNA before completing cell division. Inhibition of the Chk1 enzyme blocks this pathway, forcing cells to divide (mitosis), causing substantial DNA damage that result in their death. "The selection of a second development candidate this year from our in-house research activities underscores our research team's expertise and provides us with another potential high value development programme," said chief executive Ian Garland.FTSE TechMARK - RisersTotal Systems (TTS) 31.50p +10.53%Phytopharm (PYM) 5.50p +4.76%Parity Group (PTY) 13.25p +3.92%Sinclair Pharma (SPH) 26.50p +2.91%Elan Corporation (ELA) € 5.79 +2.84%Puricore (PURI) 19.50p +2.63%Vernalis (VER) 80.00p +2.56%ProStrakan (PSK) 100.00p +2.04%Microgen (MCGN) 70.00p +1.45%Sepura (SEPU) 47.50p +1.06%FTSE TechMARK - FallersPsion (PON) 67.25p -4.61%Oxford Biomedica (OXB) 10.50p -4.55%Skyepharma (SKP) 100.25p -4.52%Emblaze (BLZ) 35.25p -3.42%Filtronic (FTC) 35.50p -2.07%XP Power (XPP) 205.00p -1.91%Imagination Technologies (IMG) 144.00p -1.03%Axis-Shield (ASD) 340.00p -0.87%Kofax (KFX) 150.00p -0.66%BATM Advanced (BVC) 38.75p -0.64%
