Gene-editing could shorten life instead of prolonging, suggests new study

Gene-editing could shorten life instead of prolonging, suggests new study

In 2018, Chinese scientist He Jiankui defied the law and scientific consensus by boldly editing the CCR5 gene in a human embryo, expecting to confer lifelong HIV resistance. The pregnancy eventually ended in the birth of two baby girls. Now the experiment appears to have gone seriously wrong, perhaps shortening their lives.

Lithium improves muscle size and strength in mice with limb girdle muscular dystrophy

Lithium improves muscle size and strength in mice with limb girdle muscular dystrophy

Standing up from a chair, climbing stairs, brushing one's hair - all can be a struggle for people with a rare form of muscular dystrophy that causes progressive weakness in the shoulders and hips. Over time, many such people lose the ability to walk or to lift their arms above their heads.

Body's endocannabinoid system appears to be new target for drug development against OCD

Body's endocannabinoid system appears to be new target for drug development against OCD

The body's endocannabinoid system, due to the critical role it plays in regulating neurotransmitter signaling, is an enticing target for drug development against disorders associated with anxiety, stress, and repetitive behaviors, such as obsessive-compulsive disorder.

Genetically eliminating TOX factors improves eradication of solid tumors in CAR T model

Genetically eliminating TOX factors improves eradication of solid tumors in CAR T model

A decade ago researchers announced development of a cancer immunotherapy called CAR (for chimeric antigen receptor)-T, in which a patient is re-infused with their own genetically modified T cells equipped to mount a potent anti-tumor attack.
