「読み進めるほどに「腹八分目」という漠然とした言葉の奥深さが沁みてくる」
「江戸時代に「腹八分目」と言い表したヒト(貝原益軒)の直感にも感心する、楽しい読書だった」

8/24読売新聞で、奈倉有里さんが小幡史明『「腹八分目」の生物学』をご書評くださいました。☞ iwnm.jp/029735

お陰さまで売れています!

Drosophila research without FlyBase would be untenable. Time for all labs who can afford it to step up.

A reminder you/your lab can support FlyBase at Cambridge through the following link. Every bit helps. Please share if you yourself can't donate.

自分でも気に入っている部分がいくつかあるのですが、そのうちの一つがここのカロリーです。ドーナツはカロリーゼロの衝撃!

Thank you so much! Hope Hina will not be too busy on revision...!

Why use #CRISPR in #Drosophila when RNAi works so well? Because for some genes well is not good enough.

Check out new preprint from the lab demonstrating a role for Vps15 in Wingless trafficking. Something that was missed in several RNAi screens.

Images from the linked preprint showing Wingless stainings in the Drosophila wing imaginal disc. Targeting vps15 with two indepependent RNAi lines (paper also shows the same with a third line) does not result in a phenotype. In contrast, targeting vps15 with two independent sgRNA constructs and Cas9 results in strong accumulation of Wingless protein in perturbed cells.

CRISPR mutagenesis is also not perfect. A common limitation is generation of genetic mosaics, where only some cells carry gene knockouts. But our new generation of tools substatially improves on that. Described in the preprint below with flies on their way to VDRC:

Calorie restriction extends lifespan in many animal models, but the effects in humans and the mechanisms of action are not clear. A Review in Nature Reviews Endocrinology summarizes evidence regarding potential adverse effects of calorie restriction. go.nature.com/42XV1Xa 🔒
This is figure 3, which shows the molecular signalling network in the hypothalamus that regulates hunger.
