Quantitative intra-Golgi transport and organization data suggest the stable compartment nature of the Golgi

The paper challenges the classical cisternal progression model by showing that intra-Golgi transport velocity varies and Golgi residence times differ for different cargos, suggesting a stable compartment model.

Arl15 upregulates the TGFβ family signaling by promoting the assembly of the Smad-complex

This study identifies Arl15 as a regulator of TGFβ signaling by promoting Smad-complex assembly through its interaction with Smad4.

How to quantitatively measure, assess and correct the fluorescence crosstalk in the wide-field microscopy

The paper introduces a quantitative metric and protocol to measure and correct fluorescence crosstalk in wide-field microscopy using common image processing software.

Glycans function as a Golgi export signal to promote the constitutive exocytic trafficking

The paper shows that O- and N-glycans act as signals for Golgi export, affecting the trafficking of transmembrane proteins.

Amino acids stimulate the endosome-to-Golgi trafficking through Ragulator and small GTPase Arl5

The paper identifies that amino acids stimulate endosome-to-Golgi trafficking via Ragulator and Arl5, linking nutrient signaling to retrograde transport.
