The nonstructural protein NS1 of human parvovirus B19 (B19) is known to exacerbate disease activity in systemic lupus erythematosus (SLE). However, no specific medicine for B19 infection is available. The roots of Gentiana macrophylla Pall. (GM), the traditional Chinese medicine “Qinjiao,” have been used for centuries to treat rheumatic disease, including SLE. Herein, we aimed to investigate the effects of GM root extract (100 and 300 mg/kg body weight) on B19-NS1-exacerbated liver injury in NZB/W F1 mice; liver tissues were assessed by hematoxylin–eosin staining and immunoblotting. The GM root extract significantly decreased B19-NS1-exacerbated liver inflammation by suppressing the expressions of hepatic inducible nitric oxide synthase, cyclooxygenase type 2 (COX-2), interleukin (IL)-1β proteins, values of serum asparate transaminase (AST) and alanine transaminase (ALT), and lymphocyte infiltration (P < .05). It also significantly reduced the B19-NS1-exacerbated hepatic matrix metalloproteinase-9 (MMP-9) and urokinase plasminogen activator (uPA) expressions by downregulating tumor necrosis factor (TNF)-α/NF-κB (p65) signaling. These findings suggest a therapeutic potential of GM root extract against B19-NS1-exacerbated liver inflammation in SLE.

The Beneficial Effects of Raffinee in Permanent Occulted Stroke Mice
Chun-Ching Chiu,Jer-Min Lin,Li-Yi Wu,Tsai-Ching Hsu,Bor-Show Tzang 한국식품영양과학회 2019 Journal of medicinal food Vol.22 No.12
Ischemic stroke is a major cause of disability and mortality globally. Although thrombolytic therapy is routinely adopted in cases of ischemic stroke, various alternative natural neuroprotectants are also used as effective adjuvant therapies to recover neurofunction following ischemic stroke. Raffinee, a natural fermented product with strong antioxidant and neuroprotective activities, has antiatherogenic effects in animals and has exhibited neuroprotective effects in a clinical trial by recovering motor and sensory function following spinal cord lesion. This study reveals the advantageous effects of Raffinee on PC12 cells by decreasing hypoxia-induced apoptosis in mice with permanent middle cerebral artery occlusion (pMCAO) by increasing the levels of neurotrophic factors such as S100β, reducing serum inflammatory factors such as matrix metalloproteinases (MMP)-9/MMP-2 ratio, tumor necrosis factor-α, and interleukin (IL)-6 level, and increasing IL-10 levels. Significantly reduced brain infarct volume along with a favorable survival ratio was observed for pMCAO mice that received Raffinee, suggesting a neuroprotective potential of Raffinee in cases of acute ischemic stroke by suppressing apoptosis.

A high environmental temperature affects the economic performance of pigs. Heat shock protein 70 (HSP70) has been reported to participate importantly in thermotolerance. This study aims to produce transgenic pigs overexpressing porcine HSP70.2, the highly inducible one of HSP70 members, and to prove the cellular thermotolerance in the primary fibroblasts from the transgenics. A recombinant plasmid in which the sequence that encodes the porcine HSP70.2 gene is fused to green fluorescence protein (GFP) was constructed under the control of cytomegalovirus (CMV) enhancer and promoter. Two transgenic pigs were produced by microinjecting pCMV-HSP70-GFP DNA into the pronucleus of fertilized eggs. Immunoblot assay revealed the varied overexpression level (6.4% and 1.4%) of HSP70-GFP in transgenic pigs. After heating at $45^{\circ}C$ for 3 h, the survival rate (78.1%) of the primary fibroblast cells from the highly expressing transgenic pig exceeded that from the non-transgenic pig (62.9%). This result showed that primary fibroblasts overexpressing HSP70-GFP confer cell thermotolerance. We suggest that transgenic pigs overexpressing HSP70 might improve their thermotolerance in summer and therefore reduce the economic loss in animal production.

Lactoferrin (LF) has beneficial effects against various diseases. However, the effects of LF on liver fibrosis in systematic lupus erythematosus (SLE) are unknown. In this study, NZB/W F1 mice were utilized to investigate the effects of LF on SLE. Experiments reveal that LF significantly increases glutathione and 1,1-diphenyl-2-picryl-hydrazyl levels and significantly decreased malondialdehyde levels in both serum and liver in NZB/W F1 mice. LF also lowered matrix metalloproteinase-9 activity and liver inflammatory indices, such as aminotransferase and alanine aminotransferase. Notably, significantly decreased expression of fibrotic related molecules, including transforming growth factor (TGF)-β1, tumor necrosis factor-α, interleukin-1β, and TGF-β1 receptor, were observed in the livers of NZB/W F1 mice that had been treated with LF. Significantly, suppressed Smad2/3 signaling, α-smooth muscle actin, and collagen deposition were also detected. These findings reveal that LF has beneficial effects on SLE by increasing antioxidant activities and ameliorating liver inflammation and fibrosis, suggesting the therapeutic effectiveness of LF against SLE.

Accumulating evidence indicates that overconsumption of ethanol contributes in many ways to the pathogenesis of hepatic injury. Although studies indicate that taurine decreases lipogenesis, oxidative stress, and inflammatory cytokines, the protective effect of taurine against alcohol-induced liver injury is still unclear. To clarify the precise signaling involved in the beneficial effect of taurine on alcohol-induced liver injury, rats were randomly divided into four treatment groups: (1) control (Ctl), (2) alcohol (Alc), (3) Alc + taurine (Tau), and (4) Alc + silymarin (Sil). The Tau and Sil groups had lower lymphocyte infiltration and significantly lower TLR-4/MyD88 and IκB/NFκB compared to the Alc group. The inducible nitric oxide synthase (iNOS), C-reactive protein (CRP), tumor necrosis factors (TNF)-α, interleukin (IL)-6, and IL-1β were also significantly lower in the Tau and Sil groups than in the Alc group. The experimental results indicated that hepatoprotection against alcohol-induced inflammation may be mediated by decreased TLR-4/MyD88 signaling.
