Idiopathic pulmonary fibrosis treatments are limited, often with severe side effects, highlighting the need for novel options. Taraxerone has diverse biomedical properties, but its mechanism remains unclear. This study investigates taraxerone's impact and the mechanisms involved in bleomycin-induced pulmonary fibrosis in mice.

H-type blood vessels participate in alveolar bone remodeling during murine tooth extraction healing.

Objectives: We aimed to investigate whether skeletal-specific H-type blood vessels exist in alveolar bone and how they function in alveolar bone remodeling.

Materials And Methods: H-type vessels with high expression of CD31 and Endomucin (CD31 Emcn ) were immunostained in alveolar bone. Abundance and age-related changes in CD31 Emcn endothelial cells (H-ECs) were detected by flow cytometry.

Genetic polymorphisms of new 22 autosomal STR loci in the Mongolian ethnic group.

The Microreader™ 23SP ID System is a novel STR kit, but there are no Mongolian data related to this kit. In this study, allelic frequencies and forensic parameters were obtained from 505 unrelated healthy Mongolians. These samples were amplified using the kit.

Harmine enhances type H vessel formation and prevents bone loss in ovariectomized mice.

Unlabelled: Recently, researchers identified a distinct vessel subtype called type H vessels that couple angiogenesis and osteogenesis. We previously found that type H vessels are reduced in ovariectomy (OVX)-induced osteoporotic mice, and preosteoclasts are able to secrete platelet-derived growth factor-BB (PDGF-BB) to stimulate type H vessel formation and thereby to promote osteogenesis. This study aimed to explore whether harmine, a β-carboline alkaloid, is capable of preventing bone loss in OVX mice by promoting preosteoclast PDGF-BB-induced type H vessel formation.

Omentin-1 prevents inflammation-induced osteoporosis by downregulating the pro-inflammatory cytokines.

Osteoporosis is a frequent complication of chronic inflammatory diseases and increases in the pro-inflammatory cytokines make an important contribution to bone loss by promoting bone resorption and impairing bone formation. Omentin-1 is a newly identified adipocytokine that has anti-inflammatory effects, but little is known about the role of omentin-1 in inflammatory osteoporosis. Here we generated global knockout () mice and demonstrated that depletion of omentin-1 induces inflammatory bone loss-like phenotypes in mice, as defined by abnormally elevated pro-inflammatory cytokines, increased osteoclast formation and bone tissue destruction, as well as impaired osteogenic activities.

Developing a new nonbinary SNP fluorescent multiplex detection system for forensic application in China.

Nonbinary single-nucleotide polymorphisms (SNPs) are potential forensic genetic markers because their discrimination power is greater than that of normal binary SNPs, and that they can detect highly degraded samples. We previously developed a nonbinary SNP multiplex typing assay. In this study, we selected additional 20 nonbinary SNPs from the NCBI SNP database and verified them through pyrosequencing.

Objective: To examine the expression of Twist1 in cervical cancer and to explore its biological function in the progression of cervical cancer.


Methods: The expressions of Twist1 in 32 cervical cancers and matched normal tissues were examined by immunohistochemistry (IHC). Cell invasive ability and the expression of invasion-related genes were determined in RNAi-based Twist1-silencing HeLa cells.

Runx2/miR-3960/miR-2861 Positive Feedback Loop Is Responsible for Osteogenic Transdifferentiation of Vascular Smooth Muscle Cells.

We previously reported that Runx2/miR-3960/miR-2861 regulatory feedback loop stimulates osteoblast differentiation. However, the effect of this feedback loop on the osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs) remains unclear. Our recent study showed that miR-2861 and miR-3960 expression increases significantly during β-glycerophosphate-induced osteogenic transdifferentiation of VSMCs.

The role of MALAT1 correlates with HPV in cervical cancer.

Cervical cancer, the second most common type of cancer in women worldwide, is responsible for >275,100 mortalities each year and is associated with high-risk human papilloma virus (HR-HPV). HPVs have two important oncogenes, E6 and E7, which have crucial roles in malignant transformation in cervical cancer. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA originally identified in non-small cell lung cancer.

Anti-hepatoma human single-chain Fv antibody and adriamycin conjugates with potent antitumor activity.

To construct an improved biological missile, an immunoconjugate ADM-Dex-ScFv-SA3 was synthesized, which was composed of a hepatocellular carcinoma-specific, single-chain Fv antibody (ScFv-SA3) and a highly potent cytotoxic drug, adriamycin (ADM), as the warhead. Oxidized Dextran T10 (Dex-T10) was used as a linker to connect these two moieties. The 40 KD soluble anti-hepatoma human Trx-ScFv-SA3 protein was expressed in E.

Monoclonal antibody preparation of Golgi phosphoprotein 2 and preliminary application in the early diagnosis of hepatocellular carcinoma.

Golgi phosphoprotein 2 (Golph2) is a type II Golgi‑specific membrane protein, which has been found to be overexpressed in hepatocellular carcinoma (HCC) patients. The sensitivity of diagnosis of HCC using Golph2 (76%) was markedly elevated compared with alpha‑fetoprotein (AFP) (70%), and Golph2 is expected to be a novel and effective serum biomarker for the diagnosis of HCC. The aim of this study was to prepare monoclonal antibodies against Golph2 and to establish double-antibody sandwich enzyme-linked immunosorbent assay (s-ELISA), which will be used in diagnostics, therapeutics and as a tool in understanding the role of Golph2 in the pathogenesis of liver diseases and cancer.

Molecular clone and functional study of a novel hepatoma associated gene.

HTA is a novel hepatoma associated gene screened by bioinformatic strategies in our previous study. In the present investigation, the full-length sequence of the HTA gene was cloned by 3'-rapid amplification of cDNA ends (RACE) and 5'-RACE, which was 1414 bp and the open reading frame (ORF) was constituted with 3 exons and 2 introns. There are two types of splicing of the mRNA of HTA.

Construction and development of a mammalian cell-based full-length antibody display library for targeting hepatocellular carcinoma.

We present a detailed method for constructing a mammalian cell-based full-length antibody display library for targeting hepatocellular carcinoma. Two novel mammalian library vectors pcDNA3-CHm and pcDNA3-CLm were constructed that contained restriction enzyme sites NheI, ClaI and antibody constant domain. Mammalian expression vector pcDNA3-CHm contains IgG heavy-chain (HC) constant region and glycosylphosphatidylinositol anchor (GPI) that could be anchored full-length antibodies on the surface of mammalian cells.

Spaceflight alters the gene expression profile of cervical cancer cells.

Our previous study revealed that spaceflight induced biological changes in human cervical carcinoma Caski cells. Here, we report that 48A9 cells, which were subcloned from Caski cells, experienced significant growth suppression and exhibited low tumorigenic ability after spaceflight. To further understand the potential mechanism at the transcriptional level, we compared gene expression between 48A9 cells and ground control Caski cells with suppression subtractive hybridization (SSH) and reverse Northern blotting methods, and analyzed the relative gene network and molecular functions with the Ingenuity Pathways Analysis (IPA) program.

Omentin-1 attenuates arterial calcification and bone loss in osteoprotegerin-deficient mice by inhibition of RANKL expression.

Aims: Omentin-1 (also known as intelectin-1) is a recently identified visceral adipose tissue-derived cytokine that is inversely related to obesity. Our previous study showed that omentin-1 inhibits osteoblastic differentiation of calcifying vascular smooth muscle cells (CVSMCs) in vitro. This study was undertaken to investigate the effects of omentin-1 on arterial calcification and bone metabolism in vivo.

Toll-like receptor 3 (TLR3) induces apoptosis via death receptors and mitochondria by up-regulating the transactivating p63 isoform alpha (TAP63alpha).

Toll-like receptor 3 (TLR3), a member of the pathogen recognition receptors, is widely expressed in various cells and has been shown to activate immune signaling pathways by recognizing viral double-stranded RNA. Recently, it was reported that the activation of TLR3 induced apoptosis in some cells, but the detailed molecular mechanism is not fully understood. In this study, we found that in endothelial cells polyinosinic-polycytidylic acid (poly(I-C)) induced dose- and time-dependent cell apoptosis, which was elicited by TLR3 activation, as TLR3 neutralization and down-regulation repressed the apoptosis.

Omentin inhibits osteoblastic differentiation of calcifying vascular smooth muscle cells through the PI3K/Akt pathway.

Arterial calcification is positively associated with visceral adiposity, but the mechanisms remain unclear. Omentin is a novel adipokine that is selectively expressed in visceral adipose tissue. The levels of circulating omentin are decreased in obesity, and they correlate negatively with waist circumference.
