Characterization Of Different Molecular Markers For Identification Of Salmonella Enterica Serovar Typhi In Pakistani Population, Faizan Muttiullah, Fida Muhammad Khan, Fakhar-I- Abbas, Sabiha Shamim
Journal of Bioresource Management
Typhoid is caused by Salmonella enterica serovar Typhi that is usually diagnosed by using serologic and immuno-chromatographic techniques in developing counties including Pakistan, which is thought to be an unreliable diagnostic method. For accurate diagnosis we used molecular techniques to amplify 204 bp StyR-36 and 498 bp flagellin gene for the identification of Salmonella enterica serovar Typhi. This study was done on 58 individuals diagnosed positive of typhoid via serologic tests and 50 healthy individuals as a control group. Success rate of amplification for flagellin gene was 77.58% while that for StyR-36 gene was 68.97% showing that flagellin gene primer …

The epithelial-mesenchymal transition (EMT) is a cellular reprogramming mechanism that is an underlying cause of cancer metastasis. Recent investigations have uncovered an intricate network of regulation involving the TGFβ Wnt, and Notch signaling pathways and small regulatory RNA species called microRNAs (miRNAs). The activity of a transcription factor vital to the maintenance of epithelial stemness, ?Np63a, has been shown to modulate the activity of these EMT pathways to either repress or promote EMT. Furthermore, ?Np63a is a known regulator of miRNA, including those directly involved in EMT. This review discusses the evidence of ?Np63a as a master regulator of EMT …

Lipin1 (phosphatidic acid phosphatase) is a key molecule in the cells with two functions: first, it converts phosphatidic acid into diacylglycerol in the cytosol which in turn makes triglycerides. Second, in nucleus lipin1 acts as a transcriptional factor which regulates the expression of genes involved in the fatty acid oxidation and lipid metabolism. Clinically, Lpin1 gene mutations have been detected in patients with severe rhabdomyolysis accompanied with aggregated and dysfunctional mitochondria in their type II muscle fiber. Previously, we have observed that mice with lipin1 deficiency had aggregated mitochondria and abnormal autophagosomes formations by electron microscopy. The mechanism underlying the …

Serine-arginine-rich (SR) or SR-like splicing factors interact with exon junction complex proteins during pre-mRNA processing to promote mRNA packaging into mature messenger ribonucleoproteins (mRNPs) and to dictate mRNA stability, nuclear export, and translation. The SR protein family is complex, and while many classical SR proteins have well-defined mRNA processing functions, those of other SR-like proteins is unclear. Here, we show that depletion of the homologous non-classical serine-arginine-rich (SR) splicing factors Bcl2-associated transcription factor (Btf or BCLAF) and thyroid hormone receptor-associated protein of 150 kDa (TRAP150) causes mitotic defects. We hypothesized that the depletion of these SR-like factors affects mitosis indirectly …

Urinary Metabolomics To Detect Polycystic Kidney Disease At Early Stage, Amnah Mahmoud Obidan

Urinary metabolomics abilities in detection of biological effects (i.e., toxicity, disease) is compounded by high background variability. Previously, we showed mild kidney dysfunction was detectable under the stress imposed by furosemide (diuretic). Here we tested whether furosemide (FUR) can enhance the sensitivity to detect autosomal dominant polycystic kidney disease (ADPKD) at an early stage. ADPKD is one of the most common inherited renal disorders and is characterized by the growth of numerous cysts in the kidneys. Urinary metabolomics analyses, using nuclear magnetic resonance (NMR) spectroscopy, were conducted in control (WT) and diseased mice (RC) at 7 and 24 weeks of …

Extracellular signal-regulated kinase 3 (ERK3) is an atypical protein kinase of the mitogen-activated protein kinase (MAPK) family. In comparison to well-investigated ERK1/2 (classical) MAPKs, much less has been discovered about ERK3 signaling and its cellular functions. Recent studies have shown that ERK3 is overexpressed in various types of cancers such as lung cancer and breast cancer and that ERK3 promotes cancer cell migration and invasion. How ERK3 regulates cancer cell motility and invasiveness, however, is still largely unknown. RhoGTPases, including Rho, Cdc42 and Rac1, play critical roles in regulating cell motility and invasiveness through activating downstream effectors such as p21-activated …

DNp63a, a member of the p53 family of transcription factors, is overexpressed in a number of cancers and known to play a role in proliferation, differentiation, migration and invasion. DNp63a has been shown to regulate several microRNAs that play a role in both development and cancer, but to date there has not been a global analysis of p63- regulated miRNA. Using next-generation sequencing of small RNA from wild type and sip63 transfected HaCaT cells, our laboratory recently identified a number of DNp63a- regulated miRNAs by RNA-Seq studies which may serve as biomarkers of cancer progression. We identified a novel miRNA, …

Melanoma is the highest mortality rate skin cancer and the sixth most common cancer in the U.S..[1, 2] Arising from melanocytes, melanoma is known for frequent mutation of BRAF to its constitutive activation state BRAFV600E, thus over-activating its downstream MAPK targets ERK1/2 and contributing to melanoma progression.[3, 4, 5] ERK3, a less studied MAPK family protein which contributes to promoting lung, breast, cervical, head and neck (HNC) cancer metastasis, has also shown a correlation with upregulation of BRAF.[6, 7, 8, 9] However, the BRAF-ERK3 regulatory mechanism and the function of ERK3 in melanoma are still unclear. Here, we first elucidate …
