Adipose tissue macrophages (ATMs) are involved in the development of insulin resistance in obesity. We have recently shown that myeloid cell–specific reduction of HMG-CoA reductase (Hmgcr^m–/m–), which is the rate-limiting enzyme in cholesterol biosynthesis, protects against atherosclerosis by inhibiting macrophage migration in mice. We hypothesized that ATMs are harder to accumulate in Hmgcr^m–/m– mice than in control Hmgcr^fl/fl mice in the setting of obesity. To test this hypothesis, we fed Hmgcr^m–/m– and Hmgcr^fl/fl mice a high-fat diet (HFD) for 24 weeks and compared plasma glucose metabolism as well as insulin signaling and histology between the two groups. Myeloid cell–specific reduction of Hmgcr improved glucose tolerance and insulin sensitivity without altering body weight in the HFD-induced obese mice. The improvement was due to a decrease in the number of ATMs. The ATMs were reduced by decreased recruitment of macrophages as a result of their impaired chemotactic activity. These changes were associated with decreased expression of proinflammatory cytokines in adipose tissues. Myeloid cell–specific reduction of Hmgcr also attenuated hepatic steatosis. In conclusion, reducing myeloid HMGCR may be a promising strategy to improve insulin resistance and hepatic steatosis in obesity.

Fans and analysts spend the entire offseason speculating where the top free agents could go, but sometimes an under-the-radar pickup can end up making a world of difference. As positional competitions begin to heat up at Spring Training camps this month, MLB.com's beat writers were asked to identify one potentially overlooked acquisition for each of the 30 clubs. Here's who they came up with.

The Astros logo outside the Ballpark of the Palm Beaches really is something to see, all the way from Haverhill Rd. The closer you get the bigger it gets, the white "H" right there in front of the huge orange star. Underneath the "H" is the following message, white against orange: "2017 World Champions." It would have been a simple matter to put "2018" down there, too. There was room.

All eyes were on right-hander Forrest Whitley, MLB Pipeline's top pitching prospect, when he threw in the bullpen for the first time Friday in Major League camp. Astros manager AJ Hinch, assistant general manager Brandon Taubman and director of player development Pete Putila were all watching intently as Whitley threw 21 pitches -- fastballs, changeups and cutters.

Astros third baseman Alex Bregman continues to progress from the arthroscopic elbow surgery he had a month to remove bone chips.

They wrestled with the decision to start a family for five years. It's something most young couples discuss at some point. Timing is important, and considering their busy lives, even more so for Astros pitcher Joe Smith and his wife, TV sports reporter Allie LaForce. The issue facing the couple is far more momentous than most others have to deal with -- one that's a matter of life and death.

The first Hall of Famer to join the Astros at Spring Training is Craig Biggio, who was in uniform for morning workouts on Tuesday and will remain with the team throughout the week.
