Comparison of the effects of alfalfa meal and sorghum distillery residue supplementation on the methane emissions in black-feathered Taiwan native chicken.

The issue of global warming, primarily fueled by anthropogenic greenhouse gas emissions, necessitates effective strategies to address methane (CH4) emissions from both ruminants and nonruminants. Drawing inspiration from successful approaches employed in ruminants, this study evaluates the impact of supplementing the diets of Taiwan's native black-feathered chickens with alfalfa meal and sorghum distillery residues (SDRs) on CH4 emissions. Using a respiration chamber the results reveal a significant reduction in CH4 emissions when incorporating either 30% alfalfa meal or 30% SDRs into the chicken diet, demonstrating a 59% and 49% decrease, respectively, compared to the control group (P < 0.

Aqueous extracts of Ocimum gratissimum mitigate colitis and protect against AOM/DSS-induced colorectal cancer in mice.

In this study, we explored the in vivo effects of Ocimum gratissimum aqueous extracts (OGE) on colorectal cancer (CRC) development provoked by azoxymethane/dextran sodium sulfate (AOM/DSS). The results showed a significant reduction in the tumor load and tumor number for the OGEH group that received continued administration of OGE compared to the AOM/DSS group, with P values of <0.01, but this was not observed in the OGEHs group that received separated administration of OGE.

Dietary supplementation of Ocimum gratissimum improves growth performance and immune response in broilers under high ambient temperature.

Ocimum gratissimum (OG) was found to have immunity boosting effect on Taiwan country chickens and broiler chickens raised in moderate ambient temperature in previous studies, and the current study investigates its potential on the growth performance, blood traits, intestinal traits, and immune responses in Ross 308 broilers raised in high ambient temperature which can induce mild heat-stress (26 to 33 ˚C, average 30 ˚C). Two hundred 1-d-old male/female chicks were randomly assigned to a control group, three OG (1 g/kg, 3 g/kg, and 5 g/kg)/basal diet groups, and one Amoxicillin group. Data collected during the experiment indicated that the weight gain increase of 1742 g/bird to 1815 g/bird comparing control to 5 g/kg OG supplementation was statistically significant.

Involvement of matrix metalloproteinase 1 and urokinase-type plasminogen activator in the PKCα-p38 MAPK pathway-mediated progression of human liver cancer cells.

Our previous studies have shown that the plasminogen activator (PA) and matrix metalloproteinases (MMPs) proteinase systems were highly expressed in highly malignant liver cancer cells and regulated by PKCα. This study investigates whether the PKCα regulation of PA and MMPs systems is conducted through p38 mitogen-activated protein kinase (MAPK) signaling and the pathway is responsible for promoting cell progression. We found that the expressions of p38 MAPK in both highly malignant HA22T/VGH and SK-Hep-1 liver cancer cells were higher than that in other lower malignancy liver cancer cells.

Protective Effects of Aqueous Extracts on HaCaT Cells Against UVC-Induced Inhibition of Cell Viability and Migration.

Antitumorigenic Effects of ZAKβ, an Alternative Splicing Isoform of ZAK.

Sterile alpha motif (SAM)- and leucine-zipper-containing kinase (ZAK) plays a role in the regulation of cell cycle progression and oncogenic transformation. The ZAK gene generates two transcript variants, ZAKα and ZAKβ, through alternative splicing. In this study, we identified that ZAKα proteins were upregulated in tumor tissues, whereas ZAKβ proteins were mostly expressed in corresponding normal tissues.

MZF-1/Elk-1/PKCα is Associated with Poor Prognosis in Patients with Hepatocellular Carcinoma.

Protein kinase C alpha (PKCα) is a key signaling molecule in human cancer development. As a therapeutic strategy, targeting PKCα is difficult because the molecule is ubiquitously expressed in non-malignant cells. PKCα is regulated by the cooperative interaction of the transcription factors myeloid zinc finger 1 (MZF-1) and Ets-like protein-1 (Elk-1) in human cancer cells.

Coenzyme Q Enhances Ultraviolet B-Induced Apoptosis in Human Estrogen Receptor-Positive Breast (MCF-7) Cancer Cells.

Coenzyme Q (CoQ; 2,3-dimethoxy-5-methyl-1,4-benzoquinone), a major active constituent of Antrodia camphorata, has been shown to inhibit human triple-negative breast cancer (MDA-MB-231) cells through induction of apoptosis and cell-cycle arrest. Ecological studies have suggested a possible association between ultraviolet B (UVB) radiation and reduction in the risk of breast cancer. However, the underlying mechanism of the combination of CoQ and UVB in human estrogen receptor-positive breast cancer (MCF-7) remains unclear.

MZF-1/Elk-1 interaction domain as therapeutic target for protein kinase Cα-based triple-negative breast cancer cells.

Recent reports demonstrate that the expression of protein kinase C alpha (PKCα) in triple-negative breast cancer (TNBC) correlates with decreased survival outcomes. However, off-target effects of targeting PKCα and limited understanding of the signaling mechanisms upstream of PKCα have hampered previous efforts to manipulate this ubiquitous gene. This study shows that the expression of both myeloid zinc finger 1 (MZF-1) and Ets-like protein-1 (Elk-1) correlates with PKCα expression in TNBC.
