Table 1 Protein markers involved on inflammatory and atherogenic pathways, their cell action and percent of reduction by UAH and EAH 1

From: Pepsin-pancreatin protein hydrolysates from extruded amaranth inhibit markers of atherosclerosis in LPS-induced THP-1 macrophages-like human cells by reducing expression of proteins in LOX-1 signaling pathway

UAH

EAH

TGF-α

Transforming growth factor-α

It is associated with vascular pressure and atherosclerosis[27]

100

IL-4

Interleukin-4

An increase in repair macrophages (M2) is coupled with secretion of IL-10 and TGF-β[28]

69

IL-32α/β/γ

Interleukin-32α/β/γ

Pro-inflammatory cytokine. Responsible of NF-κB activation[29]

100

85

IL-22

Interleukin-22

It has a critical role in modulating local inflammation in certain organs[30]

55

70

IGFBP-3

Insulin-like growth factor-binding protein-3

High levels are related with hypertension and atherosclerosis[31]

71

63

TNF-α

Tumor Necrosis Factor-α

It is expressed by the action of different stimulus, like LPS. It acts as pro-inflammatory stimulus[32]

59

63

GRO-α

Chemokine (C-X-C motif) ligand-1

It is a pro-inflammatory chemokine and is secreted by monocytes in response to pro-inflammatory stimuli[34]

62

62

Adipose tissue-specific secretory factor

It is a pro-inflammatory cytokine[35]

14NS

62

TfR

Involved in the apoptosis of endothelial cells[36]

48

61

GDF-15

Growth differentiation factor 15

It has a role in regulating inflammatory pathway[37]

NS

60

IL-11

Interleukin-11

It is rather pro-inflammatory in chronic inflammation[38]

66

57

FGF-19

Fibroblast growth factor-19

Inhibited the hepatic fatty acid synthesis[39]

61

56

MIF

Macrophage migration inhibitory factor

It encodes a lymphokine involved in cell-mediated immunity, immunoregulation and inflammation[40]

46

53

IL-1α

Interleukin-1 α

It can induce the activation of nuclear factor-κB (NF-κB)[41]

41

53

IL-6

Interleukin-6

In chronic inflammation it is rather proinflammatory[42]

64

52

IL-12p70

Interleukin-12p70

It is a key YH-1 cytokine that drives inflammation in numerous models of intestinal inflammation[43]

100

51

PDGF-AA

Platelet-derived growth factor-AA

It has been linked to atherosclerosis[44]

50

49

RANTES

Chemokine(C-C motif) ligand-5

Involved in several clinical inflammatory conditions, such as atherosclerosis[45]

33NS

47

EMMPRIN

Extracellular-matrix metalloproteinase inducer

It is involved in cytokines activation[46]

NS

46

MCP-1

Monocyte-chemo attractant protein-1

It has been linked with chronic inflammatory diseases and atherosclerosis[4, 47]

35

19NS

41

ICAM-1

Intracellular Adhesion Molecule-1

Adhesion of monocytes is mediated by ICAM-1[4]

NS

40

IL-1β

Interleukin-1 β

Low and high levels produced inflammation, resulting in tissue damage and tumor invasiveness[41]

NS

40

MMP-9
