Special Issue Information

Dear Colleagues,

The signal transducer and activator of transcription 3 (STAT3) is a protein with polyhedral activities: it mediates, directly or indirectly, multiple cellular signaling pathways (cytokines of growth factors, hormones and oxidative stress). In addition, it is a key protein in the modulation of metabolism and mitochondrial activity and it is involved in the regulation of microtubule dynamics in the cellular cytoskeleton.
STAT3 activation is crucial in various diseases such as chronic inflammation, cardiovascular and metabolic disorders and cancer. In fact, many scientific publications have assessed the involvement of STAT3, through both its canonical and non-canonical pathways, in all three phases of carcinogenesis: initiation, progression and invasion. STAT3 can be considered a moonlighting protein and its multifaceted activities are mainly exerted via post-translational modifications such as phosphorylation, acetylation, glutathionylation and methylation and interaction with a variety of protein components.

This Special Issue aims to investigate the key role of STAT3, its PTMs and its protein ligands in the modulation of cellular functions. Moreover, this Special Issue should provide a broad and accurate account of STAT3’s cellular and biological functions; we hope that researchers in the field will contribute with research articles, review articles, innovative hypotheses or commentaries on STAT3-related activities and regulations.

STAT3 is an important transcription factor that regulates cell growth and proliferation by regulating gene transcription of a plethora of genes. This protein also has many roles in cancer progression and several tumors such as prostate, lung, breast, and intestine cancers that are characterized by strong STAT3-dependent transcriptional activity. This protein is post-translationally modified in different ways according to cellular context and stimulus, and the same post-translational modification can have opposite effects in different cellular models. In this review, we describe the studies performed on the main modifications affecting the activity of STAT3: phosphorylation of tyrosine 705 and serine 727; acetylation of lysine 49, 87, 601, 615, 631, 685, 707, and 709; and methylation of lysine 49, 140, and 180. The extensive results obtained by different studies demonstrate that post-translational modifications drastically change STAT3 activities and that we need further analysis to properly elucidate all the functions of this multifaceted transcription factor.
