positive regulation of tyrosine phosphorylation of Stat3 protein

Any process that activates or increases the rate, frequency or extent of the introduction of a phosphoric group to a tyrosine residue of a Stat3 protein.

negative regulation of tyrosine phosphorylation of Stat3 protein

Any process that stops, prevents or reduces the rate, frequency or extent of the introduction of a phosphoric group to a tyrosine residue of a Stat3 protein.

Catalysis of the transport of a solute, driven by the hydrolysis of the diphosphate bond of inorganic pyrophosphate, ATP, or another nucleoside triphosphate. The transport protein may or may not be transiently phosphorylated, but the substrate is not phosphorylated.

The formation from simpler components of hemoglobin, an oxygen carrying, conjugated protein containing four heme groups and globin.

A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a hydrogen peroxide (H2O2) stimulus.

The series of events leading to chemical and structural alterations of an existing cell wall that can result in loosening, increased extensibility or disassembly.

The formation from simpler components of the cell wall, the rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis.

positive regulation of tyrosine phosphorylation of STAT protein

Any process that activates or increases the rate, frequency or extent of the introduction of a phosphoric group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

negative regulation of tyrosine phosphorylation of STAT protein

Any process that stops, prevents or reduces the rate, frequency or extent of the introduction of a phosphoric group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

The formation from simpler components of tumor necrosis factor-alpha, an inflammatory cytokine produced by macrophages/monocytes during acute inflammation and which is responsible for a diverse range of signaling events within cells, leading to necrosis or apoptosis.
