Four putative pathogenic ARHGAP29 variants in patients with non-syndromic orofacial clefts (NsOFC).

The pathophysiological basis of non-syndromic orofacial cleft (NsOFC) is still largely unclear. However, exome sequencing (ES) has led to identify several causative genes, often with reduced penetrance. Among these, the Rho GTPase activating protein 29 (ARHGAP29) has been previously implicated in 7 families with NsOFC.

Deciphering the role of FUS::DDIT3 expression and tumor microenvironment in myxoid liposarcoma development.

Background: Myxoid liposarcoma (MLS) displays a distinctive tumor microenvironment and is characterized by the FUS::DDIT3 fusion oncogene, however, the precise functional contributions of these two elements remain enigmatic in tumor development.

Methods: To study the cell-free microenvironment in MLS, we developed an experimental model system based on decellularized patient-derived xenograft tumors. We characterized the cell-free scaffold using mass spectrometry.

Methods: The data comprised files of 1,000 fresh socket implants placed during the 2014-2019 interval in three Tehran-based private dental clinics. The statistical method was survival analysis consisting of shared frailty and intra-cluster correlation.

Different HSP90 Inhibitors Exert Divergent Effect on Myxoid Liposarcoma In Vitro and In Vivo.

The therapeutic options for patients with relapsed or metastatic myxoid liposarcoma (MLS) remain scarce and there is currently no targeted therapy available. Inhibition of the HSP90 family of chaperones has been suggested as a possible therapeutic option for patients with MLS. However, the clinical effect of different HSP90 inhibitors vary considerably and no comparative study in MLS has been performed.

Castleman's Disease Intra Parotid, a Case Report and Literature Review.

Castleman's disease (CD), otherwise known as angiofollicular lymph node hyperplasia, is a rare, poorly understood disorder, which often occurs in a mediastinum. Involvement of parotid gland is a considerably infrequent event. We present a 15-year-old boy patient with a swelling in the left parotid gland that has been diagnosed with CD.

Intraosseous ancient Schwannoma: A rare case in the mandible and a literature review.

Schwannoma, otherwise known as neurilemmoma, is a benign tumor that originates from Schwann cells. Ancient Schwannoma is a long-standing Schwannoma with degenerative and xanthomatous changes. The Head and neck region is one of the most common sites for nerve sheath tumors but Involvement of the jaw is a considerably infrequent event.

Patient-derived scaffolds as a model of colorectal cancer.

Background: Colorectal cancer is the second most common cause of cancer-related death worldwide and standardized therapies often fail to treat the more aggressive and progressive types of colorectal cancer. Tumor cell heterogeneity and influence from the surrounding tumor microenvironment (TME) contribute to the complexity of the disease and large variability in clinical outcomes.

Methods: To model the heterogeneous nature of colorectal cancer, we used patient-derived scaffolds (PDS), which were obtained via decellularization of surgically resected tumor material, as a growth substrate for standardized cell lines.

Characterization of cell-free breast cancer patient-derived scaffolds using liquid chromatography-mass spectrometry/mass spectrometry data and RNA sequencing data.

Patient-derived scaffolds (PDSs) generated from primary breast cancer tumors can be used to model the tumor microenvironment . Patient-derived scaffolds are generated by repeated detergent washing, removing all cells. Here, we analyzed the protein composition of 15 decellularized PDSs using liquid chromatography-mass spectrometry/mass spectrometry.

Patient-derived scaffolds uncover breast cancer promoting properties of the microenvironment.

Tumor cells interact with the microenvironment that specifically supports and promotes tumor development. Key components in the tumor environment have been linked to various aggressive cancer features and can further influence the presence of subpopulations of cancer cells with specific functions, including cancer stem cells and migratory cells. To model and further understand the influence of specific microenvironments we have developed an experimental platform using cell-free patient-derived scaffolds (PDSs) from primary breast cancers infiltrated with standardized breast cancer cell lines.

Effects of Lactobacillus and probiotics on the serum biochemical parameters, and the vitamin D and leptin receptor genes on mice colon cancer.

Objectives: The preclinical reports have shown that specific probiotics like () and () can be applied as the biotherapeutic agents in the inhibition or therapy of colorectal cancer via the modification of gut bacteria. In the previous studies, we have assessed the impact of and probiotics on gut bacteria concentration and also their chemo-protective impact on mice colon cancer. In the following, we assessed the effects of these probiotics on the gene expression of vitamin D receptor (VDR) and the leptin receptor (LPR) and the serum biochemical parameters on mice colon cancer.

Application of E75 peptide vaccine in breast cancer patients: A systematic review and meta-analysis.

The E75 peptide vaccine, derived from tumor-associated antigen HER2, is the most frequently studied anti-HER2 vaccination strategy for the treatment of breast cancer patients. It has been investigated in the several phases Ι/Π of the clinical trials and is currently being evaluated in a randomized multicenter phase III clinical trial. We conducted a systematic review and meta-analysis to clarify the outcomes of the E75 peptide vaccine including the therapeutic efficacy, the disease recurrence, the survival rate, and the side effects.

More Protection of Lactobacillus acidophilus Than Bifidobacterium bifidum Probiotics on Azoxymethane-Induced Mouse Colon Cancer.

Based on the ability of the probiotics in the gut microflora modification, they can have the beneficial effects on diseases in the short and/or the long term. In previous study, we revealed that unlike Bifidobacterium bifidum, the amount of Lactobacillus acidophilus remained almost unchanged in mice gut microflora in the long term, indicating more stability of L. acidophilus than B.

Modifications of mice gut microflora following oral consumption ofLactobacillus acidophilus and Bifidobacterium bifidum probiotics.

Background/aim: Thirty male BALB/c mice were equally divided into three groups: control, L. acidophilus, and B. bifidum for the assessment of the probiotics' stability in the gut microflora.

Targeting cancer stem cell-specific markers and/or associated signaling pathways for overcoming cancer drug resistance.

Cancer stem cells (CSCs) are a small subpopulation of tumor cells with capabilities of self-renewal, dedifferentiation, tumorigenicity, and inherent chemo-and-radio therapy resistance. Tumor resistance is believed to be caused by CSCs that are intrinsically challenging to common treatments. A number of CSC markers including CD44, CD133, receptor tyrosine kinase, aldehyde dehydrogenases, epithelial cell adhesion molecule/epithelial specific antigen, and ATP-binding cassette subfamily G member 2 have been proved as the useful targets for defining CSC population in solid tumors.

Caenorhabditis elegans PAQR-2 and IGLR-2 Protect against Glucose Toxicity by Modulating Membrane Lipid Composition.

In spite of the worldwide impact of diabetes on human health, the mechanisms behind glucose toxicity remain elusive. Here we show that C. elegans mutants lacking paqr-2, the worm homolog of the adiponectin receptors AdipoR1/2, or its newly identified functional partner iglr-2, are glucose intolerant and die in the presence of as little as 20 mM glucose.

Nanobiotechnological Approaches to Overcome Drug Resistance in Breast Cancer.

Drug resistance primarily appears where there is altered drug metabolism or target modification. It is a major challenge in cancer therapy which affects treatment process, and limits chemotherapeutics. Recently, nanotechnological approaches were shown to be capable of lowering drug side effects and protecting from enzymatic degradation.

A Mutation in Caenorhabditis elegans NDUF-7 Activates the Mitochondrial Stress Response and Prolongs Lifespan via ROS and CED-4.

The mevalonate pathway is responsible for the synthesis of cholesterol, coenzyme Q, and prenyl groups essential for small GTPase modification and function, and for the production of dolichols important for protein glycosylation. Statins, i.e.

Associations of Probiotics with Vitamin D and Leptin Receptors and their Effects on Colon Cancer.

Colorectal cancer (CRC) is one of most common causes of cancer-related death worldwide. Recent studies have suggested that microbial and environmental factors including diet and lifestyle can impact on colon cancer development. Vitamin D deficiency and dysfunction of vitamin D receptor (VDR) also correlate with colon cancer.

Loss of HMG-CoA reductase in C. elegans causes defects in protein prenylation and muscle mitochondria.

HMG-CoA reductase is the rate-limiting enzyme in the mevalonate pathway and the target of cholesterol-lowering statins. We characterized the C. elegans hmgr-1(tm4368) mutant, which lacks HMG-CoA reductase, and show that its phenotypes recapitulate that of statin treatment, though in a more severe form.

Citriquinones A and B, new benzoquinones from Penicillium citrinum.

Two new benzoquinones, citriquinone A (1) and B (2), were isolated from the methanol extract of a soil fungus, Penicillium citrinum. The structures of the new compounds were determined on the basis of detailed spectroscopic analysis. Citriquinone A (1) exhibited antibacterial activity against Bacillus sp.

The mitochondrial unfolded protein response activator ATFS-1 protects cells from inhibition of the mevalonate pathway.

Statins are cholesterol-lowering drugs that inhibit 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase, the rate-limiting enzyme in the synthesis of cholesterol via the mevalonate pathway. This pathway also produces coenzyme Q (a component of the respiratory chain), dolichols (important for protein glycosylation), and isoprenoids (lipid moieties responsible for the membrane association of small GTPases). We previously showed that the nematode Caenorhabditis elegans is useful to study the noncholesterol effects of statins because its mevalonate pathway lacks the sterol synthesis branch but retains all other branches.
