Modified expression of JAK-STAT pathway genes in an in vivo rheumatoid arthritis model: A preclinical study to explore genetic insights.

Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterised by inflammatory synovial tissue, joint deterioration, and effects on systems other than the joints. The biological process underlying the progression of the disease remains unknown, however cell-mediated immunity plays an important part in the onset of RA. The current study investigated the involvement of the JAK-STAT pathway genes (JAK-1, IL-6, and SOCS-2) in the pathogenesis of RA (Rheumatoid arthritis).

The pertinence of resistin gene single nucleotide polymorphism G > A and its expression in oral cancer.

Background/aim: Oral cancer (OC) is the leading cause of fatalities in Pakistan among males due to inadequate oral hygiene and chewing habits. However, genetic susceptibility patterns also play a critical role in disease progression. Since the frequency of Resistin (RETN) SNP (Single nucleotide polymorphism) rs3219175 is unknown; there is a requirement for early diagnosis of the OC.

Inflammatory markers and COVID-19 disease progression.

Background: The COVID-19 pandemic has resulted in a global humanitarian crisis. Despite ongoing research, transmission risks and many disease characteristics remained unclear. Most patients have displayed elevated levels of certain inflammatory markers, which we sought to investigate further in relation to disease severity.

Angiotensin-converting enzyme 2 (ACE2) polymorphisms and susceptibility of severe SARS-CoV-2 in a subset of Pakistani population.

Science is digging for the varied presentation of COVID-19 patients exposed to the same risk factors, and medical conditions may be influenced by the presence of polymorphic genetic variants. This study investigated the link between ACE2 gene polymorphisms and the severity of SARS-CoV-2. This cross-sectional study recruited COVID-19 PCR-positive patients by consecutive sampling from Ziauddin Hospital from April to September 2020.

Increasing Frequency of New Delhi Metallo-beta-Lactamase and Klebsiella pneumoniae Carbapenemase Resistant Genes in a Set of Population of Karachi.

Objective: To determine the frequency of Klebsiella pneumoniae Carbapenemase (blaKPC) and New Delhi Metallo-Beta-Lactamase (blaNDM) resistant genes among clinical isolates of Enterobacterales in a set of Karachi population.

Study Design: An observational study.

Place And Duration Of Study: Department of Microbiology, Dr.

Aberrant STAT1 methylation as a non-invasive biomarker in blood of HCV induced hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is one of the most common types of cancer in the world and a reason behind different oncogenes activation and tumor suppressor genes inactivation. Hyper-methylation of tumor suppressor genes including RASSF1a, GSTP1, p16, and APC cause gene silencing as well as tumor cell invasion. STAT 1 gene is a part of signaling cascade of JAK/STAT and any dysregulation in signaling has been implicated in tumor formation.

Survivin Promoter Polymorphism (-31 C/G): A Genetic Risk Factor for Oral Cancer.

Background: The polymorphism of survivin gene at its promoter region is one of the risk factors for OSCC . This polymorphism involves substitution of G for C (9904341), and it is present at the cell cycle dependent elements and cell cycle homology region repressor binding motif of promoter. This study aimed to find the association between survivin -31C/G polymorphism and prevalence of OSCC in a subset of Pakistani population.

DNA methyltransferase 1, 3a, and 3b expression in hepatitis C associated human hepatocellular carcinoma and their clinicopathological association.

Identification of biomarker will obligate a substantial influence on various cancer management and treatment. We hypothesize that genetic/proteomic and epigenetic studies should be uncovering modifications which may be independently or jointly affect the expression of the genes that are involved in the progression of liver cancer (LC). For this purpose, we examined the effect of expressional changes of DNMTs on HCV infected LC of different genotypes.

Introducing differential expression of human heat shock protein 27 in hepatocellular carcinoma: moving toward identification of cancer biomarker.

Previously, it has to be acknowledged that overexpressed heat shock protein B27 (HSPB27) have been implicated in the etiology of wide range of human cancers. However, the molecular mechanism leading to the disease initiation to progression in liver cancer is still unknown. Present work was undertaken to investigate the differentially expressed HSPB27 in association with those damages that lead to liver cancer development.

Protein expression profiling of nuclear membrane protein reveals potential biomarker of human hepatocellular carcinoma.

Background: Complex molecular events lead to development and progression of liver cirrhosis to HCC. Differentially expressed nuclear membrane associated proteins are responsible for the functional and structural alteration during the progression from cirrhosis to carcinoma. Although alterations/ post translational modifications in protein expression have been extensively quantified, complementary analysis of nuclear membrane proteome changes have been limited.
