The aberrant proliferation of nucleus pulposus (NP) cells has been reported to be implicated in the pathogenesis of intervertebral disc degeneration (IDD). Previous studies have demonstrated that microRNAs (miRNAs), which are a group of small noncoding RNAs, are critical regulators of cell proliferation in various pathologies. However, the role of miRNA‑96 (miR‑96) in the proliferation of NP cells remains to be determined. In the present study, reverse transcription‑quantitative polymerase chain reaction was used to investigate the expression of miR‑96 in NP tissues from patients with IDD and healthy tissues from patients with traumatic lumbar fracture as the control...

A key step to transform terahertz imaging to a practical medical imaging modality lies in the understanding the interactions between terahertz (THz) waves and biological tissues. Most of the models in the literature use the permittivity of liquid water to simulate the THz-tissue interactions but they often neglect the contributions from biological background such as proteins and lipids as dehydrated biological samples are experimentally difficult to prepare. In this work, we present a method to prepare thin and flat dehydrated samples which can be easily handled and measured in a transmission setup...

Ionising radiation is a well-recognised risk factor for the development of breast cancer, however, it is unknown whether radiation-specific molecular oncogenic mechanisms exist. We investigated post-Chernobyl breast cancers from radiation-exposed female clean-up workers and non-exposed controls for molecular changes. Radiation-associated alterations identified in the discovery cohort (n=38) were subsequently validated in a second cohort (n=39). Increased expression of hsa-miR-26b-5p was associated with radiation exposure in both of the cohorts...

The mitochondrial arginase type II (Arg-II) has been shown to interact with ribosomal protein S6 kinase 1 (S6K1) and mitochondrial p66(Shc) and to promote cell senescence, apoptosis and inflammation under pathological conditions. However, the impact of Arg-II on organismal lifespan is not known. In this study, we demonstrate a significant lifespan extension in mice with Arg-II gene deficiency (Arg-II(-/-)) as compared to wild type (WT) control animals. This effect is more pronounced in the females than in the males...

Feline mammary carcinoma (FMC) is a common cancer with high metastatic potential and high mortality rate. Loss of cell-cell interactions and degradation of the extracellular matrix by proteinases enhances tumour invasion and metastasis. Peripheral neoplastic foci (PNF) are defined as the presence of discrete tumour cell clusters, splitting off from central neoplastic foci (CNF) and lodging around these CNF. PNF therefore locate at the tumour-host interface at the site of invasion. The aim of this study was to evaluate immunohistochemically the expression of cell adhesion molecules (e-cadherin [CDH-1], syndecan 1 [SDC-1] and nectin-2), matrix metalloproteinases (matrix metalloproteinase [MMP]-2, MMP-7 and MMP-9) and their tissue inhibitors (tissue inhibitor of matrix metalloproteinase [TIMP]-1 and TIMP-2) together with the cellular proliferation marker, Ki67, in CNF and PNF of FMCs of different clinical stages and histological grades...

Human lung tissue, directly exposed to the environmental oxidants and toxicants, is apt to be harmed to bring about acute or chronic oxidative insults. The nuclear factor erythroid 2-related factor 2 (Nrf2) represents a central cellular defense mechanism, and is a target for developing agents against oxidative insult-induced human lung diseases. Our previous study found that the EtOH extract of Cinnamomum chartophyllum protected human bronchial epithelial cells against oxidative insults via Nrf2 activation...

Foot-and-mouth disease virus (FMDV) is a picornavirus that causes an economically significant disease in cattle and swine. Replication of FMDV is dependent on both viral proteins and cellular factors. Nonstructural protein 2B of FMDV plays multiple roles during viral infection and replication. We investigated the roles of 2B in virus-host interactions by constructing a cDNA library obtained from FMDV-infected swine tissues, and used a split-ubiquitin-based yeast two-hybrid system to identify host proteins that interacted with 2B...

The interactions that could be built between the biomaterials and tissue- microenvironments are very complex, especially in case of degradable metals that generate a broad variety of degradation products. The interfacial problems are particularly relevant for Fe-based materials that have been proposed for the development of biodegradable implants. The cell metabolism could be affected by the accumulation of insoluble Fe-containing degradation products that has been observed in vitro and in vivo as a coarse granular brownish material around the implant...

Piwi-interacting RNAs (piRNAs) are a class of small non-coding RNAs that associate with PIWI subfamily proteins, which play an important role in transposon silencing in animal germ cell. The piRNAs biogenesis is divided into two major pathways: primary and secondary, and both pathways are independent of double-stranded RNA-processing enzyme Dicer, which processes the single-stranded RNA transcripts in microRNA (miRNA) and siRNA (small interfering RNA) pathway. Primary piRNAs are processed from long non-coding RNA precursors transcribed from piRNA clusters...

Spinophilin is a multifunctional scaffold protein that regulates the formation and function of dendritic spines and plays a role in neuronal migration. The distinct roles of spinophilin depend on its localization and the direct interaction with other proteins, which may target spinophilin to specific locations within the cell. Several studies suggest a role of spinophilin in the pathophysiology of neurological or psychiatric diseases. However, the majority have been performed in animals or cultured cells. Thus, the aim of the present study was to characterise the regional and subcellular expression of spinophilin immunoreactivity by western blot in postmortem human brain...

The generation of new oligodendrocytes is essential for adult brain repair in diseases such as multiple sclerosis. We previously identified the multifunctional p57kip2 protein as a negative regulator of myelinating glial cell differentiation and as an intrinsic switch of glial fate decision in adult neural stem cells (aNSCs). In oligodendroglial precursor cells (OPCs), p57kip2 protein nuclear exclusion was recently found to be rate limiting for differentiation to proceed. Furthermore, stimulation with mesenchymal stem cell (MSC)-derived factors enhanced oligodendrogenesis by yet unknown mechanisms...

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is an important enzyme that functions in producing energy and supplying intermediates for cellular metabolism. Recent researches indicate that GAPDHs have multiple functions beside glycolysis. However, little information is available for functions of GAPDHs in potato. Here we identified four putative cytosolic GAPDH genes in potato genome. The expression analysis demonstrated that the StGAPC1, StGAPC2, and StGAPC3 are constitutively expressed in potato tissues and cold inducible in tubers...

It has long been known that patients suffering from inflammatory bowel disease (IBD) have an increased risk of developing colorectal cancer (CRC). The innate immune system of host cells provides a first-line defence against pathogenic infection, whereas uncontrolled inflammatory response under homeostatic conditions usually leads to pathological consequences, as exemplified by the chronic inflammation of IBD. The key molecules and pathways keeping innate immunity in check are still poorly defined. Here, we report that chromatin remodeler polybromo-1 (PBRM1) is a repressor of innate immune signaling mediated by RIG-I-like receptors (RLRs)...

Pleiotrophin (PTN) is a multifunctional, cationic, glycosaminoglycan-binding cytokine and growth factor involved in numerous physiological and pathological processes, including tissue repair and inflammation-related diseases. PTN has been shown to promote leukocyte responses by inducing their migration and expression of inflammatory cytokines. However, the mechanisms through which PTN mediates these responses remain unclear. Here, we identified the integrin Mac-1 (αMβ2, CD11b/CD18) as the receptor mediating macrophage adhesion and migration to PTN...
