New developments in Mid-infrared microscopic imaging instrumentation and data analysis have turned this method into a conventional technique. This imaging method offers a global analysis of samples, with a resolution close to the cellular level enabling the acquisition of local molecular expression profiles. It is possible to get chemo-morphological information about the tissue status, which represents an essential benefit for future analytical interpretation of pathological changes of tissue. In this review, we give an overview of Mid-infrared microscopic imaging and its applications in clinical research...

Intraductal carcinoma of the prostate(IDCP) is defined as a solid or cribriform neoplastic growth confined to ducts and acini, with preservation of the basal cell layer. Since IDCP can often present tumor necrosis (TN), it should be distinguished from Gleason 5 (GP5) invasive adenocarcinoma for staging and clinical purposes. In the present study we reviewed 344 radical prostatectomies performed at our institution and selected all cases with either >5% GP5 or IDCP for assessment of TN on histology slides (n = 59)...

Liver fibrosis is the underlying cause of cirrhosis and liver failure in any type of chronic liver injury. However, the function of lncRNAs in liver fibrosis is largely unknown. In this study, we performed transcriptome sequencing of CCl4 induced mouse fibrotic liver tissues and normal liver tissues, and found 118 lncRNAs and 1921 mRNAs were significantly up-regulated, whereas 59 lncRNAs and 1504 mRNAs were down-regulated in fibrotic livers. Gene ontology analysis revealed that the differentially expressed lncRNAs are implicated in cell junction, cell differentiation and cell proliferation, pathways closely associated with EMT...

Ameloblastoma(AB) is an aggressive and slow-growing tumor with high recurrence rate, which arises from odontogenic epithelium. AB mostly shows osteolytic growth, but the specific pathogenesis is not yet clear. Periostin is a considered a prominent oncogene, which was mainly produced by osteoblasts and their precursors cells, it have been proved that Periostin play an important role in bone lysis. However, the precise role of Periostin in AB progression remains unknown. In this article, the surgical specimens from cases of AB were collected, and the Periostin expression was tested and the results were analyzed for possible correlations with clinical characteristics...

Glutamine (Gln) is important not only for cell proliferation but also for differentiation. Although Gln is essential for plasmacytic differentiation of lymphocytes, no study has been done on the effect of Gln on differentiation of tumor cells, such as lymphoma. Here we examined the effect of Gln on plasmacytic differentiation of lymphoplasmacytic lymphoma (LPL) with its cell lines, MWCL-1 and RPCI-WM1. Gln promoted plasmacytic differentiation of LPL, and p38 MAPK signaling pathway mediated such differentiation...

Fibrosis is known to be the hallmarks of chronic inflammation of the bowel. Epithelial damage due to inflammation compromises the barrier function of the gastrointestinal tract. This barrier dysfunction leads to further spread of inflammation resulting in a chronic state of inflammation. This chronic inflammation leads to development of fibrosis, which has very limited therapeutic options and usually requires surgical removal of the affected tissue. Our previous work has shown that Caffeic acid phenethyl ester (CAPE) is a naturally occurring anti-inflammatory agent, found in propolis, has been found to be protective in experimental colitis via enhancement of epithelial barrier function...

OBJECTIVES: Long non-coding RNAs (lncRNAs) are a type Table of endogenous RNA longer than 200 nucleotides in length, and this kind of RNAs lack or possess limited ability of coding proteins. A large number of studies have demonstrated that lncRNAs could take part in massive biological processes, such as transcriptional activation and interference, cellular differentiation, proliferation, migration, invasion and apoptosis. The abnormal expression of lncRNAs has been clarified to play extremely important roles in various diseases, especially in human cancers...

Hepatic steatosis is common in patients infected with hepatitis C virus (HCV). Particularly in patients infected with non-genotype 3 HCV, hepatic steatosis is closely related to factors of the metabolic syndrome such as hyperlipidemia. However, the molecular mechanisms involved in this "metabolic" steatosis in non-3 genotype HCV infections are not well understood. Here, we aimed to develop an in vitro model to study the effect of genotype 1 HCV infection on hepatic lipotoxicity and lipid metabolism...
