Combined MEK and CDK4/6 inhibition (MEKi + CDK4i) has shown promising clinical outcomes in patients with NRAS- mutant melanoma. Here, we interrogated longitudinal biopsies from a patient who initially responded to MEKi + CDK4i therapy but subsequently developed resistance. Whole-exome sequencing and functional validation identified an acquired PIK3CA E545K mutation as conferring drug resistance. We demonstrate that PIK3CA E545K preexisted in a rare subpopulation that was missed by both clinical and research testing, but was revealed upon multiregion sampling due to PIK3CA E545K being nonuniformly distributed. This resistant population rapidly expanded after the initiation of MEKi + CDK4i therapy and …

Articles, Abstracts, and Reports

Preterm birth (PTB) can lead to lifelong complications and challenges. Identifying and monitoring molecular signals in easily accessible biological samples that can diagnose or predict the risk of preterm labour (PTL) in pregnant women will reduce or prevent PTBs. A number of studies identified putative biomarkers for PTL including protein, miRNA and hormones from various body fluids. However, biomarkers identified from these studies usually lack consistency and reproducibility. Extracellular vesicles (EVs) in circulation have gained significant interest in recent years as these vesicles may be involved in cell-cell communication. We have used an improved small RNA library construction protocol and …


Simpson Grading As Predictor Of Meningioma Recurrence, Ayesha Quddusi, Muhammad Shahzad Shamim May 2018

Simpson Grading As Predictor Of Meningioma Recurrence, Ayesha Quddusi, Muhammad Shahzad Shamim

Section of Neurosurgery

Meningimas are one of the commonest primary brain tumours and the commonest extra-axial primary brain tumour. Despite better understanding of the molecular pathogenesis of the tumours, surgical excision remains the treatment of choice, and in a large proportion of cases, complete excision is curative. Simpson grading for the extent of resection of meningiomas, was introduced more than six decades ago, and has stood the test of time. With modern technological advancements, however, the relevance of Simpson grading has been questioned. Herein we review the recent literature on the relevance of Simpson grading more than sixty years after its introduction.

Articles, Abstracts, and Reports

BACKGROUND: Immunotherapy with PD-1 or PD-L1 blockade fails to induce a response in about 80% of patients with unselected non-small cell lung cancer (NSCLC), and many of those who do initially respond then develop resistance to treatment. Agonists that target the shared interleukin-2 (IL-2) and IL-15Rβγ pathway have induced complete and durable responses in some cancers, but no studies have been done to assess the safety or efficacy of these agonists in combination with anti-PD-1 immunotherapy. We aimed to define the safety, tolerability, and activity of this drug combination in patients with NSCLC.

METHODS: In this non-randomised, open-label, phase 1b …

Articles, Abstracts, and Reports

Modifiers of Mendelian disorders can provide insights into disease mechanisms and guide therapeutic strategies. A recent genome-wide association (GWA) study discovered genetic modifiers of Huntington's disease (HD) onset in Europeans. Here, we performed whole genome sequencing and GWA analysis of a Venezuelan HD cluster whose families were crucial for the original mapping of the HD gene defect. The Venezuelan HD subjects develop motor symptoms earlier than their European counterparts, implying the potential for population-specific modifiers. The main Venezuelan HD family inherits HTT haplotype hap.03, which differs subtly at the sequence level from European HD hap.03, suggesting a different ancestral origin …

Medical College Documents

Primary thyroid lymphoma (PTL) is an uncommon malignancy of the thyroid gland, with most lymphomas of the thyroid being almost exclusively of the non-Hodgkin's B cell variety. PTL requires a prompt diagnosis because of its ability to cause progressive compression symptoms, and its unusual presentation can make the diagnosis very challenging. Herein, we present a case of PTL in a young woman with an uncommon initial presentation and discuss the complications she faced during the surgery, as well as postoperatively, due to the compression of the trachea by the thyroid mass.

Articles, Abstracts, and Reports

Data collected from omics technologies have revealed pervasive heterogeneity and stochasticity of molecular states within and between phenotypes. A prominent example of such heterogeneity occurs between genome-wide mRNA, microRNA, and methylation profiles from one individual tumor to another, even within a cancer subtype. However, current methods in bioinformatics, such as detecting differentially expressed genes or CpG sites, are population-based and therefore do not effectively model intersample diversity. Here we introduce a unified theory to quantify sample-level heterogeneity that is applicable to a single omics profile. Specifically, we simplify an omics profile to a digital representation based on the omics profiles …

Ligation of OX40 (CD134, TNFRSF4) on activated T cells by its natural ligand (OX40L, CD252, TNFSF4) enhances cellular survival, proliferation, and effector functions such as cytokine release and cellular cytotoxicity. We engineered a recombinant human OX40L IgG4P Fc fusion protein termed MEDI6383 that assembles into a hexameric structure and exerts potent agonist activity following engagement of OX40. MEDI6383 displayed solution-phase agonist activity that was enhanced when the fusion protein was clustered by Fc gamma receptors (FcγRs) on the surface of adjacent cells. The resulting costimulation of OX40 on T cells induced NFκB promoter activity in OX40-expressing T cells and induced …
