Mexico is a megadiverse country that has 3,600 to 4,000 species of medicinal plants, of which approximately 800 are used to treat conditions related to diabetes mellitus (DM). DM is a chronic degenerative disease of energy metabolism that exists as two types: type 1 (DM1) and type 2 (DM2). DM is considered a public health problem that affects 7% of the Mexican population older than 20 years. DM is clinically controlled with hypoglycaemic drugs, alpha-glucosidase inhibitors, insulin secretion stimulants or the direct application of insulin...

Glioblastoma (GBM) is the most common and aggressive tumor of the central nervous system. Unfortunately, patients affected by this disease have a very poor prognosis, due to high level of invasiveness and resistance to standard therapies. Although the molecular profile of GBM has been extensively investigated, the events responsible for its pathogenesis and progression remain largely unknown. Histone Deacetylases (HDAC) dependent epigenetic modifications and transforming growth factor (TGF)-β/Smad pathway seem to play an important role in GBM tumorigenesis, resistance to common therapies and poor clinical outcome...

In plants, microRNAs (miRNAs) regulate more than hundred target genes comprising largely transcription factors that control growth and development as well as stress responses. However, the exact functions of miRNA families could not be deciphered because each miRNA family has multiple loci in the genome, thus are functionally redundant. Therefore, an ideal approach to study the function of a miRNA family is to silence the expression of all members simultaneously, which is a daunting task. However, this can be partly overcome by Target Mimic (TM) approach that can knockdown an entire miRNA family...

The nutritional essentialities of transition element vanadium (V) as micro-nutrient in farm animals have not yet been established, though in rat model, vanadium as vanadate has been reported to exert insulin-mimetic effect and shown to be needed for proper development of bones. The objective of this study was to determine the effect of V supplementation on growth performance, plasma hormones and bone health status in calves. Twenty-four crossbred calves (body weight 72.83 ± 2.5 kg; age 3-9 months) were blocked in four groups and randomly assigned to four treatment groups (n = 6) on body weight and age basis...

BACKGROUND: Triple-negative breast cancers (TNBCs) are defined by their lack of oestrogen receptor, progesterone receptor and epidermal growth factor receptor 2. Although heterogeneous, the majority are aggressive and treatment options are limited. Caveolin acts as tumour suppressor or promoter depending on the cancer type. AIM: In this study, we aimed to determine if the expression levels of the candidate biomarker caveolin-1 on stromal or tumour cells were associated with clinicopathological parameters and disease outcomes in TNBCs from an ethnically diverse cohort of Asian women...

BACKGROUND AND OBJECTIVE: Previous studies firmly proved that an irregular aneurysmal shape was strongly associated with intracranial aneurysm (IA) rupture, but it is unclear how irregularly shaped intracranial aneurysms (IAs) form. We aimed to identify the factors related to irregular shape of IAs. METHOD: We retrospectively analyzed of consecutive patients evaluated or treated for IA at our institution from June 2015 to July 2016. According to the imaging morphology of aneurysm, the enrolled patients are divided into irregular and regular group...

BACKGROUND: Except for meeting the individual palliative need, the benefit of breast surgery in primary metastatic breast cancer (PMBC), also known as de novo metastatic breast cancer, on long-term outcomes remains controversial. Twenty-four hundred and one patients with metastatic breast cancer, enrolled between 2000 and 2011 in two prospective non-interventional studies on targeted therapy, were screened with respect to this question. METHODS: One study investigated trastuzumab therapy for human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer in addition to mainly first-line chemotherapy...

BACKGROUND: We investigated the associations of fibroblast growth factor 21 (FGF-21) with cardiovascular risk and β-cell function in patients who had no history of diabetes. METHODS: We enrolled 269 outpatients who had been referred for an oral glucose tolerance test (OGTT). Plasma glucose, insulin, and FGF-21 were measured before and at 2h after the OGTT. β-cell function was assessed using the insulinogenic index, corrected for insulin resistance. Patients' 10-year coronary heart disease (CHD) risk was assessed using the Chinese Multi-provincial Cohort Study functions...

Grafting of cell-seeded alginate capillary hydrogels into a spinal cord lesion site provides an axonal bridge while physically directing regenerating axonal growth in a linear pattern. However, without an additional growth stimulus, bridging axons fail to extend into the distal host spinal cord. Here we examined whether a combinatory strategy would support regeneration of descending axons across a cervical (C5) lateral hemisection lesion in the rat spinal cord. Following spinal cord transections, Schwann cell (SC)-seeded alginate hydrogels were grafted to the lesion site and AAV5 expressing brain-derived neurotrophic factor (BDNF) under control of a tetracycline-regulated promoter was injected caudally...

Platelet-derived growth factor receptor alpha (PDGFRα), a tyrosine kinase receptor, is up-regulated in hepatic stellate cells (HSCs) during chronic liver injury. HSCs mediate hepatic fibrosis through their activation from a quiescent state partially in response to pro-fibrotic growth factors. HSC activation entails enhanced expression of pro-fibrotic genes, increase in proliferation, and increase in motility, which facilitates migration within the hepatic lobule. We show co-localization of PDGFRα in murine carbon tetrachloride, bile duct ligation (BDL), and 0...

Our ability to now study disease at the most fundamental molecular level has led to a reclassification of human cancers into numerous subtypes that vary in disease progression and response to therapy. Like most solid tumors, breast cancer is a heterogeneous disease with considerable variation in histological and biological features. Triple negative breast cancer (TNBC) is a subtype of breast cancer in which estrogen receptor and progesterone receptor are not expressed, and human epidermal growth factor receptor 2 is not amplified or overexpressed...

BACKGROUND: Epithelial to mesenchymal transition (EMT) is considered to be important for cancer invasion and metastasis. Tumour hypoxia, in addition to Transforming Growth Factor-β (TGF-β) and Notch, amongst others, have been suggested to be involved in EMT. We therefore investigated if hypoxia, TGF-β1 and the Notch ligand Jagged-1 alone induced morphological changes with corresponding EMT signatures in different epithelial breast cancer cell lines in vitro. Furthermore, we also studied whether or not TGF-β1, or Jagged-1 in combination with hypoxia added any effect on EMT...

BACKGROUND & AIMS: Transforming growth factor beta (TGFB) suppresses early stages of tumorigenesis, but also contributes to migration and metastasis of cancer cells. A large number of human tumors contain mutations that inactivate its receptors, or downstream proteins such as Smad transcription factors, indicating that the TGFB signaling pathway prevents tumor growth. We investigated the effects of TGFB inhibition on liver tumorigenesis in mice. METHODS: C57BL/6 mice received hydrodynamic tail injections of transposons encoding HRAS(G12V) and a short hairpin RNA (shRNA) to downregulate p53, or those encoding HRAS(G12V) and MYC, or those encoding HRAS(G12V) and TAZ(S89), to induce liver tumor formation; mice were also given injections of transposons encoding SMAD7 or shRNA against SMAD2, SMAD3, SMAD4, or SNAI1 (Snail), with or without ectopic expression of Snail...

BACKGROUND: For patients with non-small-cell lung cancer (NSCLC) and multiple brain metastases, whole-brain irradiation (WBI) is a standard-of-care treatment, but its effects on neurocognition are complex and concerning. We compared the efficacy of an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), icotinib, versus WBI with or without chemotherapy in a phase 3 trial of patients with EGFR-mutant NSCLC and multiple brain metastases. METHODS: We did a multicentre, open-label, parallel randomised controlled trial (BRAIN) at 17 hospitals in China...

Male premature neonates are more susceptible than females to the development of bronchopulmonary dysplasia (BPD). The reasons underlying sexually dimorphic outcomes in premature neonates are not known. GDF15 (Growth and differentiation factor 15) is a secreted cytokine and plays a role in cell proliferation, apoptosis, and angiogenesis. In this study, we sought to elucidate the sex-specific expression of Gdf15 in the lung in vivo in neonatal hyperoxic lung injury and its regulation by Hif-1α, and to delineate the differences in GDF15 expression in male and female human umbilical venous endothelial cells in an in vitro model of oxygen toxicity...

Resistance to antiangiogenic therapy glioblastoma (GBM) patients may involve hypoxia-induced expression of stromal cell-derived factor (SDF)-1α receptor C-X-C chemokine receptor 4 (CXCR4) on invading tumor, macrophage/microglial cells (MGCs), and glioma stem cells (GSCs). We determined whether antagonizing CXCR4 with peptide epitope mimetic POL5551 disrupts anti-vascular endothelial growth factor therapy-induced glioma growth and dissemination. Mice bearing orthotopic CT-2A or GL261 gliomas received POL5551 and/or anti-vascular endothelial growth factor antibody B20-4...

BACKGROUND: Cell-based therapies with autologous adipose tissue-derived cells have shown great potential in several clinical studies in the last decades. The majority of these studies have been using the stromal vascular fraction (SVF), a heterogeneous mixture of fibroblasts, lymphocytes, monocytes/macrophages, endothelial cells, endothelial progenitor cells, pericytes and adipose-derived stromal/stem cells (ASC) among others. Although possible clinical applications of autologous adipose tissue-derived cells are manifold, they are limited by insufficient uniformity in cell identity and regenerative potency...

Anne M Williams, Parminder S Suchdev
Improving maternal and child nutrition is central to global development goals and reducing the noncommunicable disease burden. Although the process of becoming malnourished starts in utero, the consequences of poor nutrition extend across the life cycle and into future generations. The global nutrition targets for 2025 include reducing infant and young child growth faltering, halting the increase of overweight children, improving breastfeeding practices, and reducing maternal anemia. In this review, we address nutritional assessment, discuss nonnutritive factors that affect growth, and endorse the evidence-based interventions that should be scaled up to improve maternal and child nutrition...
