Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Transport of proteins into chloroplasts
Photosynthesis Research, 1988The import of cytoplasmically synthesized proteins into chloroplasts involves an interaction between at least two components; the precursor protein, and the import apparatus in the chloroplast envelope membrane. This review summarizes the information available about each of these components.

Transport of Proteins into Mitochondria
The Protein Journal, 2019Mitochondria are essential organelles of eukaryotic cells. They consist of hundreds of different proteins that exhibit crucial activities in respiration, catabolic metabolism and the synthesis of amino acids, lipids, heme and iron-sulfur clusters.

Membrane Transport of Proteins
Nature New Biology, 1972FACILITATED diffusion of small organic molecules across cell membranes is thought to be carrier-mediated in part because the process displays reaction kinetics. Models describing carrier transport assume that the transported molecule is associated with the membrane, reacting presumably with membrane proteins, and is then moved across the barrier.

Protein Transport into Chloroplasts
Annual Review of Plant Biology, 2010Most proteins in chloroplasts are encoded by the nuclear genome and synthesized as precursors with N-terminal targeting signals called transit peptides. Novel machinery has evolved to specifically import these proteins from the cytosol into chloroplasts.

Zinc, which is involved in the structure of all enzyme classes, is a micro nutrient element and necessary for growth and development. The ability of zinc to function without causing toxic effects is depends on the protection of its homeostasis. Zinc transporter proteins are responsible for keeping zinc at certain concentrations.

Transport through lipids and aquaporins is osmotic and entirely driven by the difference in osmotic pressure. Water transport in cotransporters and uniporters is different: Water can be cotransported, energized by coupling to the substrate flux by a mechanism closely associated with protein.

Bicarbonate transport proteins
Biochemistry and Cell Biology, 2002Bicarbonate is not freely permeable to membranes. Yet, bicarbonate must be moved across membranes, as part of CO2metabolism and to regulate cell pH. Mammalian cells ubiquitously express bicarbonate transport proteins to facilitate the transmembrane bicarbonate flux.
