These species form the main active sites for activating methane molecule.
These receptors are mainly involved in cell proliferation and survival through activation of PI3K-Akt [ 11], STAT3 [ 12], and Ras-Raf-MAPK signaling pathway, with the latter described as the main pathway activated by EGFR [ 13].
Although first identified as the main transcription factor activated under low oxygen tensions, HIF is a key transcription factor activated by cytokines, oncogenes and ROS (reactive oxygen species) under normoxic conditions [ 3].
ERK 1/2 are activated by MEK1/2, which are activated by Raf, Ras, and growth factors or mitogens; Raf activity, as the main effector of Ras, is suppressed by cyclic AMP-dependent kinase (PKA) in a normal cell [ 71].

This points to Th2 lymphocytes rather than activated macrophages as the main source of IL-6 in this system.
Phosphoantigen was originally identified as the main γδ TCR-recognized antigen that could activate γδ T cells to promote immune protection against mycobacterial infection.
Various tumours overexpress some microRNAs (miRNAs) targeting 3′ untranslated region (3′-UTR) of main activating ligand genes such as MICA, MICB and ULBP1 to avoid immune recognition.
They utilized activated sludge and biofringe as the main process parameters.
As the main protein upstream of AP-1, JNK is activated first, leading to the phosphorylation of pre-existing c-Jun and ATF2 proteins [ 21].
