Membrane trafficking is the vesicular transport system that moves proteins and lipids between organelles, enabling secretion, endocytosis and cellular signalling. Regulated by Rab GTPases, coat proteins and SNARE complexes, these pathways maintain organelle identity, nutrient uptake and membrane turnover, forming a central mechanism of eukaryotic cell organisation.

MicroRNAs are small non-coding RNAs that regulate gene expression by targeting messenger RNAs and influencing their stability and translation. Learn about miRNA biogenesis, Dicer, Argonaute, RISC, gene silencing, development, disease, cancer, and therapeutic applications.
