Abstract Biosynthesis of lipids and fatty acids (FAs) is essential for the normal functioning of cellular processes, and lipid availability determines the progression of multiple malignant tumor types. To date, the roles of individual steps in lipid biosynthesis during tumor growth and their interaction with intracellular signaling pathways are not well understood. Our study demonstrates that upregulation of de novo FA and lipid synthesis is a conserved characteristic of malignant tumors.

Abstract The autophagosomal SNARE (soluble N-ethylmaleimide–sensitive factor attachment protein) Syntaxin17 (Syx17) plays a pivotal role in autophagosome-lysosome fusion, yet the broader impact of its loss remains elusive. Our investigation of Syx17 function in Drosophila nephrocytes and salivary gland cells revealed unexpected effects.

The Ykt6–Snap29–Syx13 SNARE complex promotes crinophagy via secretory granule fusion with Lamp1 carrier vesicles - Scientific Reports

By Szabolcs Takáts
| Nature Verified
Abstract In the Drosophila larval salivary gland, developmentally programmed fusions between lysosomes and secretory granules (SGs) and their subsequent acidification promote the maturation of SGs that are secreted shortly before puparium formation. Subsequently, ongoing fusions between non-secreted SGs and lysosomes give rise to degradative crinosomes, where the superfluous secretory material is degraded.
