Abstract
Global impact of COVID-19 pandemic has heightened the urgency for efficient virus detection and identification of variants such as the Q57H mutation. Early and efficient detection of SARS-CoV-2 among densely populated developing countries is paramount objective. Although RT-PCR assays offer accuracy, however, dependence on expansive kits and availability of allied health resources pose an immense challenge for developing countries. In the current study, RT-LAMP based detection of SARS-Cov-2 with subsequent confirmation of Q57H variant through ARMS-PCR was performed. Among the 212 collected samples, 134 yielded positive results, while 78 tested negative using RT-LAMP. Oropharyngeal swabs of suspected individuals were collected and processed for viral RNA isolation. Isolated viral RNA was processed further by using either commercially available WarmStart Master Mix or our in house developed LAMP master mix separately. Subsequently, the end results of each specimen were evaluated by colorimetry. For LAMP assays, primers targeting three genes (ORF1ab, N and S) were designed using PrimerExplorer software. Interestingly, pooling of these three genes in single reaction tube increased sensitivity (95.5%) and specificity (93.5%) of LAMP assay. SARS-CoV-2 positive specimens were screened further for Q57H mutation using ARMS-PCR. Based on amplicon size variation, later confirmed by sequencing, our data showed 18.5% samples positive for Q57H mutation. Hence, these findings strongly advocate use of RT-LAMP-based assay for SARS-CoV-2 screening within suspected general population. Furthermore, ARMS-PCR also provides an efficient mean to detect prevalent mutations against SARS-Cov-2.

Abstract
Background B-cell lymphoma 2 is involved in various cancers including breast carcinoma. Its expression in breast cancer has been associated with good prognostic factors such as hormone receptor expression, low Ki-67, low grade, and earlier stage. It is also considered to be an independent prognostic factor for luminal and triple-negative tumors. Objective We aimed to determine the expression of B-cell lymphoma 2 (BCL2) in different molecular subtypes of invasive ductal carcinoma of breast and its association with prognostic indicators. Materials and Methods Fifty samples of invasive carcinoma of breast, no special type (NST), were categorized into molecular subtypes according to immunohistochemical expression of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor 2 (HER2), and Ki-67 and then evaluated for BCL2 expression. The expression of BCL2 was correlated with ER, PR, HER2, and Ki-67 and compared between luminal and nonluminal subtypes. Results The BCL2 expression was seen in 68% of the cases with a significant association with ER, PR, and luminal subtypes. No significant association of BCL2 expression was seen with grade, HER2 and Ki-67 status of the tumor, or age group of the patients. BCL2 expression is significantly associated with ER, PR, and luminal subtypes in breast cancer. Conclusion BCL2 is a marker of good prognosis in invasive carcinoma of breast, NST.

Abstract
BACKGROUND Colorectal cancers are slowly developing cancers of which more than 95% are adenocarcinomas, beginning in the mucus-producing glands lining the colon and rectum. In Pakistan, colorectal carcinoma is ranked as the seventh most common malignancy in men and the ninth most common in women with a male to female ratio of 9 to 1. This study aimed at investigating Neutrophil to Lymphocyte Ratio (NLR) as a potential marker for predicting severity of disease in terms of tumour histological grade in patients with pre-operative colorectal adenocarcinoma. METHODS Retrospective cross-sectional study design was adopted and this study was conducted at the Department of Pathology, Pakistan Institute of Medical Sciences Islamabad. Sixty patients of all age-groups and both genders, diagnosed as colorectal adenocarcinoma on histopathological examination of resected specimens, were selected by consecutive non-probability sampling. Separately, 60 healthy subjects, age and sex-matched, were selected as control. RESULTS Results revealed that the most common age group was 41-60 years showing 29 cases (48%) followed by the age group 61-80 years with 17 cases (28%). The most common site was the rectum having 24 cases (40%) followed by the right hemicolon with 13 cases (21.7%). The mean of neutrophil to lymphocyte ratio rose in direct proportion to the grade of colorectal carcinoma, showing a mean value of 4.5 in well differentiated low grade carcinoma, 5.0 in moderately differentiated and 6.0 in high grade poorly differentiated carcinoma. All patients had higher total leukocyte count, higher absolute neutrophil count, higher total neutrophil percentage and higher NLR as compared to their normal healthy counterparts. CONCLUSIONS It is concluded that the NLR is directly proportional to tumour grade so it can be used preoperatively to assess whether the tumour is advanced so that it can be dealt with accordingly. This ratio can also be used as an independent screening marker for colorectal carcinoma since it shows very low levels in normal colonic epithelium.

Abstract
The reprogramming of energy metabolism is one of the hallmarks of cancer and is crucial for tumor progression. Altered aerobic glycolysis is a well-known characteristic of cancer cell metabolism. In the present study, the expression profiles of key metabolic genes (HK2, PFKM, and PKM2) were assessed in the breast cancer cohort of Pakistan using quantitative polymerase chain reaction (qPCR) and IHC. Expression patterns were correlated with molecular subtypes and clinical parameters in the patients. A significant upregulation of key glycolytic genes was observed in tumor samples in comparison to their adjacent controls (p < 0.0001). The expression of the studied glycolytic genes was significantly increased in late clinical stages, positive nodal involvement, and distant metastasis (p < 0.05). HK2 and PKM2 were found to be upregulated in luminal B, whereas PFKM was overexpressed in the luminal A subtype of breast cancer. The genes were positively correlated with the proliferation marker Ki67 (p < 0.001). Moreover, moderate positive linear correlations between HK2 and PKM2 (r = 0.476), HK2 and PFKM (r = 0.473), and PKM2 and PFKM (r = 0.501) were also observed (p < 0.01). These findings validate that the key regulatory genes in glycolysis can serve as potential biomarkers and/or molecular targets for breast cancer management. However, the clinical significance of these molecules needs to be further validated through in vitro and in vivo experiments.

Abstract
BACKGROUND Colorectal cancer is the 4th leading cause of cancer related deaths affecting both men and women worldwide. In the present study, any probable role of MTDH mRNA expression in CRC tumorigenesis was explored using both discovery and validation cohorts. METHODS AND RESULTS After prior ethical and biosafety approvals, tumor tissue samples along with their adjacent controls were collected for this study from Pakistani patients diagnosed with colorectal cancer. RNA was isolated using Trizol reagent, followed by cDNA synthesis. Transcript analysis of MTDH was performed by using qPCR. Moreover, genome-wide expression of MTDH was also determined through micro-array data analysis using BRB-array tools software. MTDH expression was significantly high in tumor tissue samples (p < 0.05) compared to their respective controls. Likewise, results of microarray analysis also revealed overamplification of MTDH in tumor samples as compared to controls. Expression of MTDH was also found to be positively correlated with KI-67 index (p < 0.05) and were observed to be significantly upregulated in advance tumor grade (p < 0.05) and stage (p < 0.05). However, no association of MTDH overexpression with age and gender could be established. CONCLUSION Hence, it can be concluded that MTDH is a core element that plays a pivotal role in colorectal tumorigenesis irrespective of patient's age and gender. Molecular insight into the tumor microenvironment revealed MTDH as a niche, representing distinctive framework for cancer progression, thus, making it an innovative target strategy for colorectal cancer treatment.

Abstract
The underlying mechanism of fibroblast growth factor receptor 1 (FGFR1) mediated carcinogenesis is still not fully understood. For instance, FGFR1 upregulation leads to endocrine therapy resistance in breast cancer patients. The current study aimed to identify FGFR1-linked genes to devise improved therapeutic strategies. RNA-seq and microarray expression data of 1,425 breast cancer patients from two independent cohorts were downloaded for the analysis. Gene Set Enrichment Analysis (GSEA) was performed to identify differentially expressed pathways associated with FGFR1 expression. Validation was done using 150 fresh tumor biopsy samples of breast cancer patients. The clinical relevance of mRNA and protein expression of FGFR1 and its associated genes were also evaluated in mouse embryonic fibroblasts (MEFs) and breast cancer cell line (MDA-MB-231). Furthermore, MDA-MB-231 cell line was treated with AZD4547 and GANT61 to identify the probable role of FGFR1 and its associated genes on cells motility and invasion. According to GSEA results, SHH pathway genes were significantly upregulated in FGFR1 patients in both discovery cohorts of breast cancer. Statistical analyses using both discovery cohorts and 150 fresh biopsy samples revealed strong association of FGFR1 and GLI1, a member of SHH pathway. The increase in the expression of these molecules was associated with poor prognosis, lymph node involvement, late stage, and metastasis. Combined exposures to AZD4547 (FGFR1 inhibitor) and GANT61 (GLI1 inhibitor) significantly reduced cell proliferation, cell motility, and invasion, suggesting molecular crosstalk in breast cancer progression and metastasis. A strong positive feedback mechanism between FGFR1-GLI1 axis was observed, which significantly increased cell proliferation and metastasis. Targeting FGFR1-GLI1 simultaneously will significantly improve the prognosis of breast cancer in patients.

Abstract
Dysregulated immune response significantly affects hepatocellular carcinoma's (HCC) prognosis. Human Leukocyte Antigens are key in devising immune responses against HCC. Here, we investigated how HLAs modulate HCC development at the transcriptomic level. RNA-seq data of 576 patients from two independent cohorts was retrieved. The clinicopathological relevance of all HLA genes was investigated using Fisher-Exact, correlation, and Kaplan-Meier and cox regression survival tests. Clustering of ~800 immune-related genes against HLAs was completed using a ward-agglomerative method. Networks were generated using 40 HLA associated unique genes and hub genes were investigated. HLAs including HLA-DMA, HLA-DMB, HLA-DOA and HLA-DRB6 were associated with delayed recurrence in both discovery (204 HCC cases) and validation (372 HCC cases) cohorts. Clustering analyses revealed 40 genes associated with these four HLAs in both cohorts. A set of seven genes (NCF4, TYROBP, LCP2, ZAP70, PTPRC, FYN and WAS) was found co-expressed at gene-gene interaction level in both cohorts. Furthermore, survival analysis revealed seven HLA-linked genes as predictors of delayed recurrence. Multivariate analysis also predicted that mean expression of 7-gene is an independent predictor of delayed recurrence in both cohorts. We conclude that the expression of 7-gene signature may lead to improved patient prognosis. Further studies are required for consideration in clinical practice.

Abstract
BACKGROUND Ki-67 is a proliferation marker that is used not only to categorize patients in luminal A and B subtypes of breast cancers, but also to determine the aggressiveness of the disease in triple negative and human epidermal growth factor 2 (HER2) over expressed molecular subtypes. The present study was designed to evaluate the role of Ki-67 with cut off value of 14% in molecular subgroups and its association with patient prognosis. METHODS Immunostaining was performed on histopathologically confirmed sections (n = 278) to assess expression of Ki-67, estrogen receptor (ER), progesterone receptor (PR) and HER2. Immunoreactivity of molecules was recorded as percentage scoring. RESULTS Adopting a cut off value of 14%, Ki-67 was high in 88%of the cases included in the study. High Ki-67 was significantly associated with pathological parameters including histological grade, advanced stage and nodal/distant metastasis. Immunoexpression of ER, PR and HER2 also showed strong correlation with high expression of Ki-67. Based on the St. Gallen classification, the cases were categorized into luminal A (10%) and luminal B (51%), triple negative (20%) and HER2 enriched (18%). Ki-67 index was also significantly high in 98% of HER2 enriched and 95% of TNBC patients. Interestingly, Ki-67 score with cut off value of 14% proved to be significant in deciphering prognosis in luminal patients. Moreover, high expression of Ki-67 also proved to be a marker of poor prognosis, especially in triple negative patients. CONCLUSION We suggest that utilization of IHC4 status i.e. ER, PR, HER2 and Ki-67 along with pathological findings and molecular subtyping can considerably affect clinical as well as therapeutic decisions.

Abstract
Background Initiation, promotion, progression, and metastasis of mammary tumors are mediated by dysregulation of multiple genes involved in various signaling pathways. Expressional variation of these molecules significantly influences cancer cell proliferation in breast cancer. Aims and Objectives In the current study, tumor necrosis factor-alpha (TNF-α) and its downstream effector nuclear factor kappa-B1 (NF-κB1) mean transcript levels were explored and associated with molecular subtypes in breast cancer cohort of Pakistan. Freshly excised tumors (n = 150) along with background tissues were collected for RNA isolation and cDNA synthesis. Materials and Methods Quantitative polymerase chain reaction was carried out for quantification of TNF-α, NF-κB1, and β-actin gene transcripts along with estrogen receptor, progesterone receptor, HER2, and Ki-67, followed by statistical analysis. Results For TNF-α and NF-κB1, 95% and 77% of the cohort was found to be positive, respectively. Both of these molecules were found to be significantly upregulated in tumors when compared against their respective controls (P < 0.0001). Association of TNF-α and NF-κB1 with late clinical stages, poorly differentiated tumors, increased tumor size, nodal involvement, and metastasis was observed to be statistically significant (P < 0.05). Strong positive correlation was established between TNF-α and NF-κB1(r = 0.465, P< 0.05). Moreover, mean transcript levels of TNF-α and NF-κB1 were significantly elevated in Luminal A and Luminal B subtypes of breast cancer patients, respectively. Conclusion Strong positive correlation between TNF-α and NF-κB1 proposed the putative role of these molecules as prognostic biomarkers in breast cancer.

Abstract
YAP1 plays a key role as a transcriptional coactivator in the Hippo pathway. Based on conflicting reports regarding YAP1 function in cancer, this study discerned its role in breast carcinogenesis. First, a systematic review of salient breast cancer studies targeting YAP1 dysregulation was performed. Additionally, freshly excised tumor specimens of approximately 200 breast cancer patients were processed for quantification of YAP1 expression at mRNA and protein levels using quantitative PCR and immunohistochemistry, respectively. YAP1 expression was nine folds higher in tumors versus controls and significantly associated with metastasis (p < 0.05) and poor survival in Pakistani breast cancer patients. These findings establish the role of YAP1 overexpression in tumorigenesis and metastasis. Hence, YAP1 inhibition may be considered a possible therapeutic strategy.

Abstract
BACKGROUND The Coronavirus disease (COVID-19) pandemic has shaken the world. So far, CT has emerged as main stay of imaging whereas the local data on radiographic features of COVID-19 is sparse. METHODS Prospective study includes 402 chest X rays (CXRs) of 105 patients presenting with symptoms of COVID-19. The nature of abnormality, distribution and lung zone involvement was documented. Following British Society of Thoracic Imaging (BSTI) guidelines, CXRs were grouped into classic/ probable COVID-19, indeterminate, non-COVID-19 and normal categories. The lung involvement was scored according to modified Radiographic Assessment of Lung Edema (RALE) scoring. The follow up radiographs were assessed for disease progression and improvement. RESULTS Seventy-six males and 29 females with mean age of 50 years were included in our study. 47 out of 105 baseline radiographs were categorized as classic/ probable COVID-19, 26 as indeterminate, 7 as Non-COVID-19 and 25 as normal. 75 patients were positive and 30 were negative on RT-PCR testing. The sensitivity of CXR in diagnosing COVID-19 is 84%. The worsening radiographic features and higher RALE score correlates with longer hospital stay, ICU admissions and mortality. The ground glass opacities and consolidations in peripheral distribution involving bilateral mid and lower zones are the predominant findings of COVID-19 in Pakistani population. CONCLUSIONS Combination of bilateral peripheral ground glass opacities and consolidations are the cardinal feature of COVID-19 on CXRs. The diagnostic categories described by BSTI correlates with PCR results in Pakistani population. The worsening radiographic findings correspond to poor prognosis; hence serial radiographs can be used for assessing disease course.

Abstract
Background Dysregulation of hedgehog pathway is observed in numerous cancers. Relevance of hedgehog pathway genes in cancer cohort and inhibition of its downstream effector (GLI1) towards metastasis in cell lines are explored in the study. Method One hundred fifty fresh tumours of breast cancer patients were collected for the study. Based on differential expression, panel of 6 key regulators of the pathway (SHH, DHH, IHH, PTCH1, SMO and GLI1) in microarray datasets were identified. Expressional profiles of aforementioned genes were later correlated with clinico-pathological parameters in Pakistani breast cancer cohort at transcript and protein levels. In addition, GLI1 over expressing breast cancer cell lines (MDA-MB-231 and MCF-7) were treated with GANT61 to explore its probable effects on metastasis. Result SHH, DHH, PTCH1 and GLI1 were significantly over-expressed in tumours as compared with respective normal mammary tissues. A significant correlation of SHH, DHH and GLI1 expression with advanced tumour size, stages, grades, nodal involvement and distant metastasis was observed (p < 0.05). Over-expression of SHH, DHH and GLI1 was significantly related with patients having early onset and pre-menopausal status. Of note, hedgehog pathway was frequently up regulated in luminal B and triple negative breast cancer affected women. In addition, positive correlations were observed among aforementioned members of pathway and Ki67 (r-value: 0.63–0.78) emphasizing their role towards disease progression. Exposure of GANT61 (inhibitor for GLI1) significantly restricted cell proliferation, reduced cell motility and invasion. Conclusion Role of activated hedgehog pathway in breast cancer metastasis provides a novel target for cancer therapy against aggressive cancer subtypes.

Abstract
BACKGROUND/AIM Constitutive activation of Sonic hedgehog (SHH) has been observed in different types of cancers. In the present study, expressional profiling of SHH in a breast cancer cohort (n=150) of a Pakistani population and its association with different molecular subtypes have been explored. MATERIALS AND METHODS qRT-PCR and IHC were performed for expression analysis of SHH and its association with ER, PR, HER2 and Ki-67 were also statistically analyzed. RESULTS A significant over-expression of SHH was observed in tumor tissues in comparison to their respective controls (p<0.0001). A strong positive correlation was seen between SHH and proliferation marker (r=0.635, p=0). SHH expression was significantly high among patients with advanced tumor grade, stage, nodal involvement and metastasis. Furthermore, both luminal-B and triple-negative subtypes of cohort showed increased expression of SHH. CONCLUSION Based on these findings, SHH may be used as a potential biomarker for breast carcinogenesis.

Abstract
BACKGROUND/AIM In the current study, the role of plexin B1 in breast cancer metastasis was explored. MATERIALS AND METHODS Freshly-excised tumours along with background tissues of affected patients (n=121) were collected from Pakistani hospitals and processed for RNA isolation and cDNA synthesis. Using quantitative polymerase chain reaction, expression of plexin B1 was evaluated and correlated with clinicopathological parameters. Furthermore, involvement of plexin B1 in metastasis was explored by generating gene knockdown in MDA-MB-231 and MCF-7 breast cancer cells. RESULTS Poorly-differentiated tumours showed low plexin B1 expression in comparison to well-differentiated ones. Similarly, reduced plexin B1 expression correlated positively with advanced tumour stage and metastasis. Loss of plexin B1 significantly reduced cell adhesion in comparison with respective control cell lines (p<0.05). Knockdown of plexin B1 in MDA-MB-231 cells led to a remarkable increase in cell motility in contrast to the respective control. CONCLUSION Loss of plexin B1 expression might play a pivotal role in enhancing the metastatic potential of breast cancer cells.

Abstract
BACKGROUND Genetic and expression anomaly of HER-2 have been frequently observed in different cancers. However, an overall association of HER-2 polymorphism (Ile655Val) with available cancer studies has not yet been explored. In the present study, a probable correlation of HER-2 Ile655Val polymorphism with 6 major types of cancers including breast, lung, gastric, ovarian, thyroid and uterine has been collectively assessed. METHODOLOGY Extensive data mining was performed using online available medical research databanks including Pubmed, Ovid, Medline and Embase. Research articles were retrieved based on common keywords "HER-2, polymorphism, (SNP) and cancer (including breast, gastric, lung, ovarian, thyroid and uterine). A database was maintained and updated for case control studies of HER-2 genotype Ile655Val (rs1136201) information until February 2015. Based on selection criteria, a total of 41 studies containing 37,111 subjects (17845 patients, 19266 controls) were selected for thorough insight about HER-2. RESULTS A significant risk association of HER-2 Ile655Val polymorphism was observed in different types of cancer using various genetic models (co-dominant heterogeneous Ile/Val vs Ile/Ile; OR=1.1, 95% CI = 1.01-1.16, P = 0.01 and dominant; OR = 1.12, 95% CI = 1.03-1.20, P = 0.0003). Interestingly, a strong correlation of Ile655Val heterogeneity was seen in the stratified subgroup of different population including African-American (co-dominant homogenous Val/Val vs Ile/Ile; OR = 8.7, 95% CI = 2.5-30.4, P = 0.0001, dominant; OR = 1.3, 95% CI = 1.03-1.7, P = 0.003; recessive; OR = 8.3, 95% CI = 2.4-28, P = 0.0002), Caucasians (co-dominant heterogeneous Ile/Val vs Ile/Ile; OR = 1.1, 95% CI = 1.0 - 1.2, P = 0.03, dominant; OR = 1.12, 95% CI = 1.0-1.2, P = 0.01). However, in Asian ethnic group, Ile655Val polymorphism lacked a significant association with cancer. This may be attributed to limited studies explored so far. CONCLUSION In summary, the current study reveals a significant association between cancer susceptibility and the HER-2 Ile655Val polymorphism in all genetic models.

Abstract
Abstract
Introduction
Hedgehog pathway dysregulation is observed in different types of cancers including breast. In the present study, expression profiles of hedgehog pathway molecules in breast cancer cohort of Pakistan and their probable association with molecular sub-types were explored.
Methods
The study was preceded with ethical approval and informed consent from respective institutions and participants. During 2013-2015, a total of 150 cancer biopsies along with adjacent normal tissues were prospectively collected immediately after surgery and processed for RNA isolation. Transcriptional profiles of salient members including SHH, DHH, IHH, PTCH-1, SMO and GLI-1 were quantified using qRT-PCR. Cohort was categorized into molecular sub-types following St. Gallen International Expert Consensus System. Association of expression levels of these aforementioned molecules with various clinico-pathological parameters was explored.
Result
Both SHH (p=0.01) and DHH (p<0.001) showed elevated expression among tumors in comparison to their controls. Similarly, PTCH-1 (p<0.001) and GLI-1 (p=0.002) were also significantly up regulated in the cohort. Interestingly, strong positive correlations were observed among the pathway molecules (r-value ranging from 0.45 to 0.81) which highlight their interdependence towards tumor progression. A significant correlation of SHH, DHH, PTCH-1 and GLI-1 was observed with advanced tumor sizes, stages, grades and nodal involvement (p<0.05). Association of IHH, SMO and GLI-1 over expression with cancer metastasis was also established in the cohort. SHH, PTCH-1 and GLI-1 were significantly linked with laterality, age and menopausal status. Expression of SHH (p=0.002) was more related to younger age group (mean age < 45 yrs) patients in comparison to elderly women.
Moreover all hedgehog molecules were strongly related to hormonal receptors (ER and PR) (r-value ranging from 0.51 to 0.86) while over-expression of HER-2 was not associated with any pathway component. Briefly, 53% (79) of the cohort was categorized as Luminal-B, 18% (27) triple negative, 15% (23) Luminal-A and 14% (21) HER-2 for sub-typing of breast cancer patients in the cohort. Expression of SHH was significantly associated with the molecular sub-types (p=0.02) and age (p=0.005) using Pearson Chi-Square test. Elevated expression of SHH was observed in 60% of the patients in Luminal B sub-type.
Conclusion
Hedgehog pathway plays a crucial role in breast cancer progression and is found to be activated in Luminal B sub-type in this cohort. As Luminal B is a more aggressive type of breast cancer having poor prognosis and early-onset, association of SHH with Luminal-B and younger age patients signify it importance as a biomarker for early diagnosis of young patient's. Hence therapeutic interventions for hedgehog pathway can improve the prognosis of patients categorized as Luminal B subtype of breast carcinogenesis.

Abstract
Cancer progression is attained by uncontrolled cell division and metastasis. Increase in tumor size triggers different vascular channel formation to address cell nutritional demands. These channels are responsible for transferring of nutrients and gaseous to the cancer cells. Cancer vascularization is regulated by numerous factors including vascular endothelial growth factors (VEGFs). These factors play an important role during embryonic development. Members included in this group are VEGFA, VEGFB, VEGFC, PIGF and VEGFD which markedly influence cellular growth and apoptosis. Being freely diffusible these proteins act in both autocrine and paracrine fashions. In this review, genetic characterization these molecules and their putative role in cancer staging has been elaborated. Prognostic significance of these molecules along with different stages of cancer has also been summarized. Brief outline of ongoing efforts to target hot spot target sites against these VEGFs and their cognate limitations for therapeutic implications are also highlighted.
