Phytoparasitic nematodes are plant pests causing serious problems to a broad range of hosts, and Meloidogyne species are widely recognized as the most damaging among the root knot nematode groups. During the incompatible interaction between avirulent pathogens and resistant tomato cultivars, juvenile nematode invasions provoke a defense cascade, culminating in hypersensitive responses. Methods to detect the key molecules involved in oxidative metabolism of the infected tomato roots are described here.

Plants have evolved a sophisticated innate immune system to contend with potential infection by various pathogens. Understanding and manipulation of key molecular mechanisms that plants use to defend against various pathogens are critical for developing novel strategies in plant disease control. In plants, resistance to attempted pathogen infection is often associated with hypersensitive response (HR), a form of rapid programmed cell death (PCD) at the site of attempted pathogen invasion. In this chapter, we describe a method for rapid identification of genes that are essential for plant innate immunity...

Corneal neovascularization is a sight-threatening condition caused by angiogenesis in the normally avascular cornea. Neovascularization of the cornea is often associated with an inflammatory response, thus targeting VEGF-A alone yields only a limited efficacy. The NF-κB signaling pathway plays important roles in inflammation and angiogenesis. Here, we study consequences of the inhibition of NF-κB activation through selective blockade of the IKK complex IκB kinase β (IKK2) using the compound IMD0354, focusing on the effects of inflammation and pathological angiogenesis in the cornea...

BACKGROUND: Multipotent mesenchymal stem cells (MSCs) are used clinically in regenerative medicine. Our previous report showed systemically injected MSCs improved peri-implant sealing and accelerated tissue healing. However, the risks of systemic MSC administration, including lung embolism, must be considered; therefore, their local application must be assessed for clinical safety and efficacy. We investigated differences in treatment effect between local and systemic MSC application using a rat oral implantation model...

Accumulating evidence has suggested that calpain small subunit 1 (Capn4) plays an important role in the development and progression of malignant tumors. However, little is known about the role of Capn4 in colorectal cancer (CRC). In this study, we aimed to investigate the potential role of Capn4 in CRC and the regulation of Capn4 by microRNAs (miRNAs). Here, we found that Capn4 expression was highly up-regulated in CRC cell lines. Knockdown of Capn4 by siRNA significantly inhibited the proliferation and invasion of CRC cell lines...

Cathepsin L (CTSL) is a lysosomal cysteine protease overexpressed and secreted by tumor cells. Our previous study found that CTSL was involved in ionizing radiation (IR)-induced epithelial-mesenchymal transition (EMT) and the increase of glioma invasion and migration. However, the mechanisms by which CTSL promoted this IR-induced glioma migration and invasion remained unclear. In this study, we demonstrated that IR reduced glycogen synthase kinase-3β (GSK-3β) activity, via the CTSL-mediated phosphorylation of its serine-9 residue, in U251 cells...

FePt-Cys nanoparticles (FePt-Cys NPs) have been well used in many fields, despite their poor solubility and stability. We synthetized a cysteine surface modified FePt NPs, which exhibited good solubility, stability and biocompatibility. We explored the insight mechanisms of the antitumor effects of this new nanoparticle system in lung cancer cells. In the in vitro study, FePt-Cys NPs induced a reactive oxygen species (ROS) burst, which suppressed the antioxidant protein expression and induced cell apoptosis...

The epithelial-mesenchymal transition (EMT) transcription factor SNAIL is associated with distant metastasis and poor prognosis of esophageal squamous cell carcinoma (ESCC) patients. The proteolysis of SNAIL is mediated by the ubiquitin-proteasome system. Several E3 ligases have been characterized to promote SNAIL ubiquitination and degradation. However, the reverse process - deubiquitination of SNAIL remains largely unknown. In this study, we performed a mass spectrometry to examine the interaction between SNAIL and deubiquitinating enzyme(s)...

Since disturbed metabolic conditions such as obesity and diabetes can be critical determinants of breast cancer progression and therapeutic failure, we aimed to determine the mechanism responsible for their pro-oncogenic effects. Using non-invasive, epithelial-like ERα-positive MCF-7 and T47D human breast cancer cells we found that hyperglycaemia induced epithelial to mesenchymal transition (EMT), a key programme responsible for the development of metastatic disease. This was demonstrated by loss of the epithelial marker E-cadherin together with increases in mesenchymal markers such as vimentin, fibronectin and the transcription factor SLUG, together with an enhancement of cell growth and invasion...

The poor outcome of hepatocellular carcinoma (HCC) is mainly due to the development of fast growth, invasion and metastasis. The role of TET2 has been implicated in some cancer types, but its role and mechanisms in HCC remains elusive. In this study, our findings indicated that TET2 expression frequently increased in HCC and that TET2 expressional upregulation correlated with HCC progression. TET2 knockdown inhibited HCC cells proliferation in vitro and growth in vivo, and inhibited the invasion potential of HCC cells...

The Xanthomonas genus includes Gram-negative plant-pathogenic bacteria, which infect a broad range of crops and wild plant species, cause symptoms with leaf blights, streaks, spots, stripes, necrosis, wilt, cankers and gummosis on leaves, stems and fruits in a wide variety of plants via injecting their effector proteins into the host cell during infection. Among these virulent effectors, transcription activator-like effectors (TALEs) interact with the γ subunit of host transcription factor IIA (TFIIAγ) to activate the transcription of host disease susceptibility genes...

Bone strength is affected not only by bone mineral density (BMD) and bone microarchitecture but also its microenvironment. Recent studies have focused on the role of marrow adipose tissue (MAT) in the pathogenesis of bone loss. Osteoblasts and adipocytes arise from a common mesenchymal stem cell within bone marrow and many osteoporotic states, including aging, medication use, immobility, over - and undernutrition are associated with increased marrow adiposity. Advancements in imaging technology allow the non-invasive quantification of MAT...
