https://www.selleckchem.com/products/pluripotin-sc1.html Mitochondria possess multiple copies of mitochondrial DNA (mtDNA) that encode 37 genes and their transcription and replication get controlled by unique molecular codes different from that in the nuclear DNA. The mtDNA has been gaining increased attention as one of the critical therapeutic targets as mutations in them impair the function of mitochondria and cause mitochondrial diseases like MELAS. In this chapter, we describe artificial control of mitochondrial transcription based on mtDNA sequence information with a new type of compounds termed MITO-PIPs, which encompasses two domains pyrrole-imidazole polyamide as DNA recognition domain and mitochondrial penetrating peptide as the mitochondria-targeting domain. Because MITO-PIPs are amenable to tunability, they can be expanded as a synthetic strategy to modulate mitochondrial gene(s) on demand.Ca2+ handling by mitochondria is implicated in energy production, shaping of cytosolic Ca2+ rises, and determination of cell fate. It is therefore of crucial interest for researchers to directly measure mitochondrial Ca2+ concentration [Ca2+] in living cells. Synthetic fluorescent Ca2+ indicators, providing a straightforward loading technique, represents a tempting strategy. Recently, we developed a new highly selective mitochondria-targeted Ca2+ indicator named mt-fura-2 , obtained by coupling two triphenylphosphonium cation-containing groups to the molecular backbone of the cytosolic ratiometric Ca2+ indicator fura-2 .The protocols we describe here cover all the significant steps that are necessary to characterize the probe and apply it to biologically relevant contexts. The procedures reported are referred to mt-fura-2 but could in principle be applied to characterize other mitochondria-targeted Ca2+ probes . More in general, with the due modifications, this chapter can be considered as a handbook for the characterization and/or application of mitochondria-targeted c
