The macrophage galactose-type C-type lectin 1 receptor plays a major role in mediating colitis-associated colorectal cancer malignancy.

Cancer-associated aberrant glycosylation can be detected by the macrophage galactose-type C-type lectin (MGL) receptor; however, whether this interaction enhances or deadens cancer development along with the associated immune response has not been well established. To determine the role of mouse MGL1 in colitis-associated colon cancer (CAC), azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced tumor development was compared between Mgl1 knockout (Mgl1) mice and their wild-type (WT) littermates. At 75 days post-CAC induction, colon tumor tissue contained more highly glycosylated proteins, representing potential ligands for the mMGL1 receptor, than did healthy colon tissue.

Endogenous innate sensor NLRP3 is a key component in peritoneal macrophage dynamics required for cestode establishment.

The NLRP3 receptor can assemble inflammasome platforms to trigger inflammatory responses; however, accumulating evidence suggests that it can also display anti-inflammatory properties. Here, we explored the role of nucleotide-binding oligomerization domain pyrin-containing protein 3 (NLRP3) in Taenia crassiceps experimental infection, which requires immune polarization into a Th2-type profile and peritoneal influx of suppressive macrophages for successful colonization. NLRP3 deficient mice (NLRP3) were highly resistant against T.

Helminth-derived molecules improve 5-fluorouracil treatment on experimental colon tumorigenesis.

Colorectal cancer (CRC) is one of the most prevalent fatal neoplasias worldwide. Despite efforts to improve the early diagnosis of CRC, the mortality rate of patients is still nearly 50%. The primary treatment strategy for CRC is surgery, which may be accompanied by chemotherapy and radiotherapy.

Alternative conformations of a group 4 Late Embryogenesis Abundant protein associated to its in vitro protective activity.

Late Embryogenesis Abundant (LEA) proteins are a group of intrinsically disordered proteins implicated in plant responses to water deficit. In vitro studies revealed that LEA proteins protect reporter enzymes from inactivation during low water availability. Group 4 LEA proteins constitute a conserved protein family, displaying in vitro protective capabilities.

Macrophage Migration Inhibitory Factor (MIF) is a Key Player in Dry Eye Disease.

Purpose: To explore the role of the proinflammatory cytokine, macrophage migration inhibitory factor (MIF), in a murine model of dry eye disease (DED).

Methods: The role of MIF on DED was determined using genetically MIF deficient mice and pharmacological inhibition of MIF. DED was induced with 0.

Targeting macrophage migration inhibitory factor (MIF): a promising therapy for inflammatory ocular diseases.

Inflammatory ocular diseases are characterized by the presence of a persistent inflammatory response which cause tissue injury, decrease visual acuity and in severe cases, blindness. Several cytokines represent a therapeutic opportunity since they are key amplifiers of these pathologies, and thus neutralizing agents against them have been developed. Amongst others, macrophage migration inhibitory factor (MIF), an early produced inflammatory cytokine, has consistently been found elevated in patients with distinct ocular diseases (inflammatory and autoimmune).

N -Methyladenosine modification of mRNA contributes to the transition from 2D to 3D growth in the moss Physcomitrium patens.

Plants colonized the land approximately 470 million years ago, coinciding with the development of apical cells that divide in three planes. The molecular mechanisms that underly the development of the 3D growth pattern are poorly understood, mainly because 3D growth in seed plants starts during embryo development. In contrast, the transition from 2D to 3D growth in the moss Physcomitrium patens has been widely studied, and it involves a large turnover of the transcriptome to allow the establishment of stage-specific transcripts that facilitate this developmental transition.

Mexican Colorectal Cancer Research Consortium (MEX-CCRC): Etiology, Diagnosis/Prognosis, and Innovative Therapies.

In 2013, recognizing that Colorectal Cancer (CRC) is the second leading cause of death by cancer worldwide and that it was a neglected disease increasing rapidly in Mexico, the community of researchers at the Biomedicine Research Unit of the Facultad de Estudios Superiores Iztacala from the Universidad Nacional Autónoma de México (UNAM) established an intramural consortium that involves a multidisciplinary group of researchers, technicians, and postgraduate students to contribute to the understanding of this pathology in Mexico. This article is about the work developed by the Mexican Colorectal Cancer Research Consortium (MEX-CCRC): how the Consortium was created, its members, and its short- and long-term goals. Moreover, it is a narrative of the accomplishments of this project.

Transcriptional Regulation of zma- by Action of Nitrate and Auxin in Maize.

In recent years, miR528, a monocot-specific miRNA, has been assigned multifaceted roles during development and stress response in several plant species. However, the transcription regulation and the molecular mechanisms controlling expression in maize are still poorly explored. Here we analyzed the zma- promoter region and found conserved transcription factor binding sites related to diverse signaling pathways, including the nitrate (TGA1/4) and auxin (AuxRE) response networks.

Argonaute5 and its associated small RNAs modulate the transcriptional response during the rhizobia- symbiosis.

Both plant- and rhizobia-derived small RNAs play an essential role in regulating the root nodule symbiosis in legumes. Small RNAs, in association with Argonaute proteins, tune the expression of genes participating in nodule development and rhizobial infection. However, the role of Argonaute proteins in this symbiosis has been overlooked.

Expression of growth arrest specific 1 (Gas1) in the distal tubules and collecting ducts in normal kidney and in the early stages of diabetic nephropathy.

The Growth Arrest-Specific protein 1 (Gas1) has been recently described in kidney as an endogenous inhibitor of cell proliferation in mesangial cells and with an important role in the maintenance of nephron progenitor cells. Furthermore, the expression of Gas1 was demonstrated in NCAM + progenitor parietal cells of Bowman's capsule. Thus, the aim of this study was to analyze the expression of Gas1 in the collecting ducts (CD) of healthy rats and to examine whether high glucose levels modify its expression during the early stages of diabetes in STZ-treated rats.

Methylation of Subtelomeric Chromatin Modifies the Expression of the lncRNA TERRA, Disturbing Telomere Homeostasis.

The long noncoding RNA (lncRNA) telomeric repeat-containing RNA (TERRA) has been associated with telomeric homeostasis, telomerase recruitment, and the process of chromosome healing; nevertheless, the impact of this association has not been investigated during the carcinogenic process. Determining whether changes in TERRA expression are a cause or a consequence of cell transformation is a complex task because studies are usually carried out using either cancerous cells or tumor samples. To determine the role of this lncRNA in cellular aging and chromosome healing, we evaluated telomeric integrity and TERRA expression during the establishment of a clone of untransformed myeloid cells.

Mast Cells in Immune-Mediated Cholangitis and Cholangiocarcinoma.

Cholestasis, which is impaired bile flow from the liver into the intestine, can be caused by cholangitis and/or bile duct obstruction. Cholangitis can arise from bacterial infections and cholelithiasis, however, immune-mediated cholangitis in primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) is characterized by a strong immune response targeting the biliary epithelial cells (BECs). Persistent biliary inflammation further represents a risk for biliary neoplasia, cholangiocarcinoma (CCA) by driving chronic cellular stress in the BECs.

Proteasome inhibition alters mitotic progression through the upregulation of centromeric α-Satellite RNAs.

Cell cycle progression requires control of the abundance of several proteins and RNAs over space and time to properly transit from one phase to the next and to ensure faithful genomic inheritance in daughter cells. The proteasome, the main protein degradation system of the cell, facilitates the establishment of a proteome specific to each phase of the cell cycle. Its activity also strongly influences transcription.

MicroRNA Zma-miR528 Versatile Regulation on Target mRNAs during Maize Somatic Embryogenesis.

MicroRNAs (miRNAs) are small non-coding RNAs that regulate the accumulation and translation of their target mRNAs through sequence complementarity. miRNAs have emerged as crucial regulators during maize somatic embryogenesis (SE) and plant regeneration. A monocot-specific miRNA, mainly accumulated during maize SE, is zma-miR528.

The canonical RdDM pathway mediates the control of seed germination timing under salinity.

Plants respond to adverse environmental cues by adjusting a wide variety of processes through highly regulated mechanisms to maintain plant homeostasis for survival. As a result of the sessile nature of plants, their response, adjustment and adaptation to the changing environment is intimately coordinated with their developmental programs through the crosstalk of regulatory networks. Germination is a critical process in the plant life cycle, and thus plants have evolved various strategies to control the timing of germination according to their local environment.

Origin and Evolutionary Dynamics of the miR2119 and ADH1 Regulatory Module in Legumes.

MicroRNAs are important regulators of gene expression in eukaryotes. Previously, we reported that in Phaseolus vulgaris, the precursor for miR2119 is located in the same gene as miR398a, conceiving a dicistronic MIR gene. Both miRNA precursors are transcribed and processed from a single transcript resulting in two mature microRNAs that regulate the mRNAs encoding ALCOHOL DEHYDROGENASE 1 (ADH1) and COPPER-ZINC SUPEROXIDE DISMUTASE 1 (CSD1).

Food-grade titanium dioxide (E171) induces anxiety, adenomas in colon and goblet cells hyperplasia in a regular diet model and microvesicular steatosis in a high fat diet model.

Food-grade titanium dioxide (E171) is a white additive widely used in solid and liquid food products. There is still debate about E171 toxic effects after oral consumption since this additive is deposited in colon, liver, spleen, testis and brain. The consumption of E171 commonly occurs with Western diets that are characterized by a high fat content.

Intranasal Immunization of Mice with Multiepitope Chimeric Vaccine Candidate Based on Conserved Autotransporters SigA, Pic and Sap, Confers Protection against .

Shigellosis is a diarrheal disease and the World Health Organization prompts the development of a vaccine against . The autotransporters SigA, Pic and Sap are conserved among a spp. We previously designed an in silico vaccine with immunodominat epitopes from those autotransporters, and the GroEL protein of typhi as an adjuvant.

NLRP3 receptor contributes to protection against experimental antigen-mediated cholangitis.

Inflammatory diseases of the bile ducts like primary sclerosing colangitis (PSC) are characterized by a robust cellular response targeting the biliary epithelium leading to chronic inflammation and fibrosis. Driving fibro-inflammatory diseases, NOD-like receptors such as NLRP3 have been identified as a central component to immune-mediated pathology. However, to date the role of NLRP3 in biliary diseases has been poorly explored.

Determining the Protective Activity of IDPs Under Partial Dehydration and Freeze-Thaw Conditions.

Unlike for structured proteins, the study of intrinsically disordered proteins (IDPs) requires selection of ad hoc assays and strategies to characterize their dynamic structure and function. Late embryogenesis abundant (LEA) proteins are important plant IDPs closely related to water-deficit stress response. Diverse hypothetical functions have been proposed for LEA proteins, such as membrane stabilizers during cold stress, oxidative regulators acting as ion metal binding molecules, and protein protectants during dehydration and cold/freezing conditions.

A birds'-eye view of the activity and specificity of the mRNA m A methyltransferase complex.

Appropriate control of the transcriptome is essential to regulate different aspects of gene expression during development and in response to environmental stimuli. Fast accumulating reports are recognizing and functionally characterizing several types of modifications across transcripts, which have created a new field of RNA study named epitranscriptomics. The most abundant modification found in messenger RNA (mRNA) is N6-methyladenosine (m A).

MGL1 Receptor Plays a Key Role in the Control of Infection by Increasing Macrophage Activation through Modulation of ERK1/2, c-Jun, NF-κB and NLRP3 Pathways.

Macrophage galactose-C type lectin (MGL)1 receptor is involved in the recognition of () parasites and is important for the modulation of the innate and adaptive immune responses. However, the mechanism by which MGL1 promotes resistance to remains unclear. Here, we show that MGL1 knockout macrophages (MGL1 Mφ) infected in vitro with were heavily parasitized and showed decreased levels of reactive oxygen species (ROS), nitric oxide (NO), IL-12 and TNF-α compared to wild-type macrophages (WT Mφ).

All-Trans Retinoic Acid Attenuates Fibrotic Processes by Downregulating TGF-β1/Smad3 in Early Diabetic Nephropathy.

Diabetic nephropathy (DN) involves damage associated to hyperglycemia and oxidative stress. Renal fibrosis is a major pathologic feature of DN. The aim of this study was to evaluate anti-fibrogenic and renoprotective effects of all-trans retinoic acid (ATRA) in isolated glomeruli and proximal tubules of diabetic rats.
