How is lc3-II create?
Best insight from top research papers
LC3-II is created through post-translational modifications of LC3-I. LC3-I is a cytosolic form of LC3, while LC3-II is membrane-bound . The C-terminal fragment of LC3 is cleaved immediately after synthesis to produce LC3-I . A fraction of LC3-I is then converted into LC3-II, which associates with autophagosome membranes . LC3-II is formed by the conjugation of LC3-I to phosphatidylethanolamine (PE) . This modification is similar to the ubiquitylation process, involving enzymes Apg7p and Apg3p . Other mammalian homologues of yeast Atg8, such as GABARAP and GATE16, also generate LC3-II and associate with autophagosomal membranes . The amount of LC3-II is correlated with the extent of autophagosome formation .

What are the advantages of LC-MS for 3-MCPD determination?5 answersLC-MS offers several advantages for the determination of 3-MCPD. Firstly, LC-MS provides high sensitivity, allowing for the detection of low levels of 3-MCPD esters in food samples. Secondly, LC-MS allows for the simultaneous quantification of multiple analytes, such as 2-MCPD and 3-MCPD, in a single analysis. Thirdly, LC-MS provides accurate and reliable results, as demonstrated by the good accuracy, high sensitivity, and satisfactory repeatability achieved in the validation of the method. Additionally, LC-MS offers a rapid analysis time, making it a time-efficient technique for 3-MCPD determination. Finally, LC-MS allows for the use of internal standards, such as deuterium isotope-labeled compounds, to improve the accuracy and precision of the analysis. Overall, LC-MS is a powerful analytical technique for the determination of 3-MCPD, offering sensitivity, accuracy, speed, and the ability to analyze multiple analytes simultaneously.
What is the function of lc3 in phagocytosis?5 answersLC3, or microtubule-associated protein 1A/1B-light chain 3, plays a role in phagocytosis by promoting the fusion of phagosomes with lysosomes for degradation of pathogens and cellular debris. LC3-associated phagocytosis (LAP) is a noncanonical autophagy process that involves the recruitment of LC3 onto phagosomes to form LAPosomes, which then mature into phagolysosomes for efficient killing of pathogens. LAP is assisted by certain autophagy factors, including members of the Atg8a (LC3) conjugation system and the Vps34 lipid kinase complex. The recruitment of LC3 to phagosomes is triggered by raised vacuolar pH and involves the assembly of the vacuolar ATPase on the vacuole membrane, which binds ATG16L1 to recruit the core LC3 conjugation complex. However, the bactericidal properties of LC3 recruitment in phagocytic cells are still unclear.

Why is the increase in LC3B-II not consistent with the decrease in p62?5 answersThe increase in LC3B-II is not consistent with the decrease in p62 because they are regulated by different mechanisms. LC3B-II is involved in autophagosome formation and is a marker of autophagy activation, while p62 is a selective substrate for autophagy.LC3B-II levels can increase due to increased autophagic flux or increased expression of LC3B, while p62 levels decrease when autophagy is activated and p62 is degraded.The regulation of LC3B and p62 is complex and can be influenced by various factors, including nutrient availability, signaling pathways, and cellular stress.Therefore, the increase in LC3B-II and the decrease in p62 may not always occur simultaneously and can be influenced by different cellular processes and conditions.
What is liquidity creation?5 answersLiquidity creation refers to the process by which financial intermediaries, such as banks, generate and provide liquid funds to the economy. It is a core function of banks and plays a crucial role in economic growth. Liquidity creation involves transforming liquid liabilities, such as deposits, into illiquid assets, such as loans and investments. Banks create liquidity by facilitating easy access to funds for households and businesses, enabling them to consume and invest. This process contributes to economic growth by boosting tangible investment, but its impact on intangible investment is limited. The relationship between internal control and liquidity creation is complex, with an inverted U-shaped relationship observed. The effectiveness of liquidity creation may vary based on economic conditions, such as economic growth rate and policy uncertainty.
