Features of liver injury in 138 Chinese patients with NICCD.

Objectives: To find biochemical and molecular markers can assist in identifying serious liver damage of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) patients.

Methods: 138 patients under 13 days to 1.1 year old diagnosed of NICCD in our center from 2004 to 2020.

Epidermal growth factor and tumor necrosis factor α cooperatively promote the motility of hepatocellular carcinoma cell lines via synergistic induction of fibronectin by NF-κB/p65.

Background: The interaction between hepatocellular carcinoma (HCC) cells and their microenvironment plays a fundamental role in tumor metastasis. The HCC microenvironment is rich in epidermal growth factor (EGF) and tumor necrosis factor α (TNFα), which may cooperatively, rather than individually, interact with tumor cells to influence their biological behavior.

Methods: Immunohistochemistry was performed to study the expression of EGF and TNFα in HCCs.

The TGF-β-induced up-regulation of NKG2DLs requires AKT/GSK-3β-mediated stabilization of SP1.

Natural killer (NK) cells play an important role in preventing cancer development. NK group 2 member D (NKG2D) is an activating receptor expressed in the membrane of NK cells. Tumour cells expressing NKG2DL become susceptible to an immune-dependent rejection mainly mediated by NK cells.

Histone deacetylase inhibitors deplete myeloid-derived suppressor cells induced by 4T1 mammary tumors in vivo and in vitro.

Myeloid-derived suppressor cells (MDSC) have been identified as a population of immature myeloid cells that suppress anti-tumor immunity. MDSC are increased in tumor-bearing hosts; thus, depletion of MDSC may enhance anti-tumor immunity. Histone deacetylase inhibitors (HDACi) are chemical agents that are primarily used against hematologic malignancies.

CCL21 Facilitates Chemoresistance and Cancer Stem Cell-Like Properties of Colorectal Cancer Cells through AKT/GSK-3β/Snail Signals.

Some evidence indicated that chemoresistance associates with the acquisition of cancer stem-like properties. Recent studies suggested that chemokines can promote the chemoresistance and stem cell properties in various cancer cells, while the underling mechanism is still not completely illustrated. In our study, we found that CCL21 can upregulate the expression of P-glycoprotein (P-gp) and stem cell property markers such as Bmi-1, Nanog, and OCT-4 in colorectal cancer (CRC) HCT116 cells and then improve the cell survival rate and mammosphere formation.

RNAi-mediated plant protection against aphids.

Aphids (Aphididae) are major agricultural pests that cause significant yield losses of crop plants each year by inflicting damage both through the direct effects of feeding and by vectoring harmful plant viruses. Expression of double-stranded RNA (dsRNA) directed against suitable insect target genes in transgenic plants has been shown to give protection against pests through plant-mediated RNA interference (RNAi). Thus, as a potential alternative and effective strategy for insect pest management in agricultural practice, plant-mediated RNAi for aphid control has received close attention in recent years.

Expression and significance of Nodal in human cancers: a meta-analysis.

Cancer is a global and growing problem. Nodal, which has been showed to be involved in occurrence and development of cancers, is an important embryonic morphogen. The aim of this study was to evaluate the significance of Nodal expression in human cancers based on the published related articles.

TGF-β and EGF induced HLA-I downregulation is associated with epithelial-mesenchymal transition (EMT) through upregulation of snail in prostate cancer cells.

Human leukocyte antigen class I antigens (HLA-I) is essential in immune response by presenting antigenic peptides to cytotoxic T lymphocytes. Downregulation of HLA-I is observed in primary and metastatic prostate cancers, which facilitates them escape from immune surveillance, thereby promotes prostate cancer progression. In addition, elevated level of growth factors like TGF-β or EGF in microenvironment is related to the prostate cancer deterioration.

Snail regulated by PKC/GSK-3β pathway is crucial for EGF-induced epithelial-mesenchymal transition (EMT) of cancer cells.

Cancer metastasis is considered a major challenge in cancer therapy. Recently, epidermal growth factor (EGF)/epidermal growth factor receptor (EGFR) signaling has been shown to induce epithelial-mesenchymal transition (EMT) and thereby to promote cancer metastasis. However, the underlying mechanism has not been fully elucidated.

AKT/GSK-3β regulates stability and transcription of snail which is crucial for bFGF-induced epithelial-mesenchymal transition of prostate cancer cells.

Background: Epithelial-mesenchymal transition (EMT) plays a pivotal role in the development of metastatic cancers. Basic fibroblast growth factor (bFGF) is significantly elevated in metastatic prostate cancers, which has been mentioned mainly to induce EMT in normal cells. However, there is no description about bFGF induced EMT and its underlying mechanism in prostate cancer cells.

The expression analysis of silk gland-enriched intermediate-size non-coding RNAs in silkworm Bombyx mori.

Small non-protein coding RNAs (ncRNAs) play important roles in development, stress response and other cellular processes. Silkworm is an important model for studies on insect genetics and control of Lepidopterous pests. We have previously identified 189 novel intermediate-size ncRNAs in silkworm Bombyx mori, including 40 ncRNAs that showed altered expression in different developmental stages.

Expression analysis and binding experiments of chemosensory proteins indicate multiple roles in Bombyx mori.

Chemosensory proteins (CSPs) are a family of small soluble proteins that, in addition to the odorant-binding proteins (OBPs), are involved in chemical communication. To understand the physiological function of the 16 known CSPs in the silkworm Bombyx mori, we investigated the expression patterns in different tissues and developmental stages using quantitative real-time RT-PCR (Q-PCR) and Western blot analysis. The results indicated that most CSPs were widely expressed in embryos, larvae, pupae and adults but were developmentally regulated.

Histone deacetylase inhibitor induction of epithelial-mesenchymal transitions via up-regulation of Snail facilitates cancer progression.

Histone deacetylase inhibitors (HDACIs) are now emerging as a new class of anticancer drugs. Some of them have been used in clinical treatment for tumors, most impressively in the hematological tumors. But their single-agent activities in epithelial-derived tumors are limited.
