June 22 (Reuters) - U.S. stock index futures were little changed on Thursday as oil edged up from multi-month lows but prices remained under pressure.
* U.S. crude futures were up 0.4 percent at $42.70 per barrel. They closed down 1.6 percent on Wednesday after touching their lowest level since August. Global benchmark Brent traded at around $45.24.
* Since peaking in late February, crude has dropped around 20 percent, skidding into bear market territory, despite OPEC-led efforts to balance the market.

* Economic data on Thursday is expected to show jobless claims for last week increased by 3,000 to 240,000, but remain at levels consistent with a tight labor market. The data is expected at 8:30 a.m. ET (1230 GMT).
* On Wednesday, the S&P 500 and Dow indexes were weighed down by falling energy shares as oil prices fell, while healthcare and tech stocks helped lift the Nasdaq.
