Mutations in the non-coding genome contribute to autism

Mutations in the non-coding genome contribute to autism

GeneticsNeurobiology

A significant portion of an organism’s genome is non-coding; that is, it does not carry information to make proteins. Part of the non-coding DNA is transcribed into functional non-coding RNA molecules (e.g., transfer RNA, ribosomal RNA and regulatory RNA). Other functions of non-coding DNA include transcriptional and translational regulation of protein coding sequences, nuclear scaffold […]

From advertising to the workplace, it is often assumed that men and women are fundamentally different – from Mars and Venus, respectively. Of course, we all know people who are more androgynous, having a mix of personality traits that are stereotypically considered to be male or female. Importantly, such “psychological androgyny” has long been associated […]

The intranasal route is a rapid, efficient and direct way for different biological agents, small molecules, drugs and chemical compounds to reach the brain. It seems amazing, but people that snort a line of coke already knew that… To date, its mechanism of diffusion is believed to be using either olfactory nerve tracts or dense […]

Coronavirus in the brain

Neurobiology

By José Ramón Alonso

To date, more than 50 million people have been infected with the new coronavirus, SARS-CoV-2, and more than 1,2 million have died. It is a global problem, affecting everyone, but we are still learning how it infects, how it behaves, what causes harm to humans. The virus is spread by the droplets produced by an […]
