An Automated Organotypic SCN Culture System Revealing Novel Insights into VIP Regulation of Circadian Rhythm.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In mammals, the suprachiasmatic nucleus (SCN) functions as the primary driver of circadian rhythm. Although individual SCN neurons exhibit cell-autonomous oscillations, intercellular communication-mediated by neural peptides such as vasoactive intestinal polypeptide (VIP)-synchronizes their rhythms. However, the precise molecular mechanism by which VIP facilitates SCN synchronization remains elusive. Here, we introduce an automated ex vivo culture system, termed 'brain-slice-in-a-chamber' (BaSIC), tailored for SCN slices, as well as dissociated cells culture. This apparatus automates medium exchange and ensures optimal control over temperature and humidity, ensuring a stable internal environment conducive to tissue culture. Furthermore, BaSIC enables real-time observation of tissue responses to diverse but programmed stimuli. Using BaSIC, we demonstrate that VIP pulsing rapidly resets the circadian rhythm by synchronizing both phase and amplitude through a swift reduction of Period 2 (PER2) protein. Mathematical modeling, coupled with experimental validation, further suggests that VIP promotes the rapid reduction of PER2. Our findings, facilitated by BaSIC, provide new insights into SCN neuron synchronization, paving the way for advanced studies in chronobiology, with potential therapeutic applications for circadian disorders.
