Our results suggest that a higher frequency of p53 genetic mutations and increased AgNOR values exist in SCC compared with BCC and SCP. 'Consequently, SCC patients may have poorer prognosis'.
Proper wound healing is dynamic in order to maintain the corneal integrity and transparency. Impaired or delayed corneal epithelial wound healing is one of the most frequently observed ocular defect and difficult to treat. Cyclin dependen kinase (cdk), a known cell cycle regulator, required for proper proliferating and migration of cell. We therefore investigated the role of cell cycle regulator cdk10, member of cdk family and its functional association with transcriptional factor (ETS2) at active phase of corneal epithelial cell migration. Our data showed that cdk10 was associated with ETS2, while its expression was upregulated at the active phase (18 hours) of cell migration and gradually decrease as the wound was completely closed. Topical treatment with anti-cdk10 and ETS2 antibodies delayed the wound closure time at higest concentration (10 µg/ml) compared to control. Further, our results also showed increased mRNA expression of cdk10 and ETS2 at active phase of migration at approximately 2 fold. Collectively, our data reveals that cdk10 and ETS2 efficiently involved during corneal wound healing. Further studies are warranted to better understand the mechanism and safety of topical cdk10 and ETS2 proteins in corneal epithelial wound-healing and its potential role for human disease treatment.
Background: Lungs are the second most common reported site of distant metastasis in Breast cancer after bone. Mostly the studies were conducted in cell lines and animal model. To date, there is no blood biomarker reported that could determine the breast cancer progression in terms of lung metastasis. Objective: The aim of this study is to determine Nidogen-1 (NID1)’s mRNA and protein expressions in non-invasive blood samples of breast cancer, in early (II) and lung metastasis advanced stages (III & IV) of naive and treated groups. To determine the functional association of NID1, we employed an in silico analysis, STRING database version 11. Methods: A total of n = 175 cases of breast cancer were recruited in our study. Real time quantitative PCR and ELISA were performed to analyze the mRNA and protein expressions of NID1 respectively. An in silico method is also used to assess NID1’s interactome. Some significant patents related to this topic were also studied and discussed in this research paper. Results: The results show high levels of NID1’s mRNA in the naive group (Group A) as compared to treated group (Group B). Similar trend of increased NID1’s protein expressions was also observed among naive and treated groups, respectively. Our results also show the significant impact of treatment on NID1’s gene and protein expressions. In silico analysis has revealed the functional association of NID1 with its different interactome protein partners. Conclusions: The increased expression of NID1 in early to advanced naive as compared to the treated groups with lung metastasis makes it a promising marker which has pro-metastatic role in breast cancer.
This molecular genetics study was conducted in Karachi, Pakistan from 2004 to 2006 to provide guidelines for prenatal diagnosis programmes in the country. Blood samples of patients with beta-thalassaemia minor (n = 200) and beta-thalassaemia major (n = 150) were collected from hospitals, transfusion centres and diagnostic laboratories from different districts of Karachi, representing 5 major ethnic groups. Molecular analysis revealed 11 genetic mutations of the beta-thalassaemia gene, among which 5 mutations accounted for 88% of the total beta-thalassaemia genes identified
Background and Objective: This study was conducted to determine the common mutation of low density lipoprotein receptor in patients with familial hypercholesterolemia (FH) in our population and identify the different point mutation in the LDL-receptor gene. The main aim of this study was to reduce the cost of PCR without extracting DNA and do the diagnosis at single step. Methods: This study was carried out in the period of one year, from 2009- 2011. All the patients selected for this study were from Dr. Ziauddin Hospital, National Institute of Cardiovascular Diseases, and Dr. Rubina Ghani’s Pathological & Molecular Laboratories. While collecting the blood sample, the patients were in overnight fasting condition. The clinical and biochemical analysis was performed on hyperlipidemic patients (n=120) to determine the frequency of familial hypercholesterolemia in our population. After lipid profile the patients were selected and direct multiplex PCR (Polymerase chain reaction) was performed from whole blood collected in a single tube using forward and reverse primers of exons 3, 4, 9 and 14 of without extracting DNA. Results: Genomic DNA was extracted from blood samples as well as direct whole ETDA blood of healthy control group and hypercholesterolemia patients to detect mutations in exons 3, 4, 9, and 14 of the LDLR gene, with modification in the technique by using type-specific primers. These results for exon 4 mutation were confirmed by DNA sequencing. Conclusion: Screening method based on PCR by using Kappa direct PCR could be a faster and cheaper method with least contamination for screening a large number of FH patients for mutation of LDLR gene.
