Interleukin-1β (IL-1β) is a key proinflammatory cytokine that initiates several signaling cascades, including those involving CCAAT/enhancer binding proteins (C/EBPs). The mechanism by which IL-1β propagates a signal that activates C/EBP has remained elusive. Nemo-like kinase (NLK) is a mitogen-activated protein kinase (MAPK)-like kinase associated with(More)
Cyclins are essential for cell proliferation, the cell cycle and tumorigenesis in all eukaryotes. UbcH10 regulates the degradation of cyclins in a ubiquitin-dependent manner. Here, we report that UbcH10 is likely involved in tumorigenesis. We found that cancer cells exposed to n-acetyl-leu-leu-norleucinal (ALLN) treatment and UbcH10 depletion exhibit a(More)
Continual high expression of cysteine proteases calpain I and II have been implicated in tumorigenicity; conversely, N-acetyl-leu-leunorleucinal (ALLN), which inhibits calpain I and II, should also influence tumor growth and carcinogenesis. To explore the role of ALLN against colon cancer and in promoting apoptosis, we used colon cancer HCT116 cell lines,(More)
Anthocyanin is widely distributed in plant organs such as root, stem, leaf, flower and fruit, being a kind of secondary metabolites generated in plant morphogenesis or for stress response. Leaf anthocyanin has special chemical structure and spectral properties, playing important roles in plant photoprotection, and becomes a hotspot in plant photosynthetic(More)
Renal cell carcinoma (RCC) is the most lethal of all urological cancers and tumor angiogenesis is closely related with its growth, invasion, and metastasis. Recent studies have suggested that epidermal growth factor-like domain multiple 7 (EGFL7) is overexpressed by many tumors, such as colorectal cancer and hepatocellular carcinoma; it is also correlated(More)
Taking 1-year old Morus alba variety 'Qinglong' seedlings as test materials, this paper studied their growth and photosynthetic characteristics under the stresses of different concentration neutral salt NaCl and alkali salt Na2CO3. Salt stresses decreased the plant height and the leaf number, biomass, and photosynthetic capacity of the seedlings markedly.(More)
By using Biolog technique, this paper studied the carbon source utilization characteristics of microbial communities in different layers (0-10 cm, 10-20 cm, and 20-30 cm) of a petroleum-contaminated soil near an oil well having exploited for 36 years in Daqing Oil Field. Petroleum contamination enhanced the metabolic activity of the soil microbial(More)
In order to further understand membrane fouling mechanism of various protein systems during ultrafiltration, polyethersulfone (PES) ultrafiltration membrane with relative molecular weight cut off of 50 x 10(3) was used, the ultrafiltration processes of three kinds of protein solution were investigated: lysozyme ( LYS), bovine serum albumin ( BSA), and LYS +(More)
A root separation experiment was conducted to investigate the plant growth and rhizosphere soil microbes and enzyme activities in a mulberry/soybean intercropping system. As compared with those in plastic barrier and nylon mesh barrier treatments, the plant height, leaf number, root length, root nodule number, and root/shoot ratio of mulberry and soybean in(More)
An orthogonal regression field experiment was conducted to study the effects of combined fertilization of N, P, and K on the nicotine content in the upper leaves of filling type flue-cured tobacco (Nicotiana tobacum) variety "Longjiang 911" from Northeast China. The regression effect models of N, P, and K fertilization rates and upper leaf nicotine content(More)
