Establishment of a clinical cancer genetics program for breast cancer in a resource-limited country; challenges and opportunities.

Breast cancer is the most common cancer among women worldwide, and its incidence rate is still increasing, especially among younger women. Nationally, it constitutes one-fifth of all cancer cases and almost 40% of all female cancers. With a median age of 51 years, breast cancer is diagnosed at least a decade earlier, and at more advanced stages compared to Western societies.

Circulating hsa-miR-320a and its regulatory network in type 1 diabetes mellitus.

Introduction: Increasing evidence from human and animal model studies indicates the significant role of microRNAs (miRNAs) in pancreatic beta cell function, insulin signaling, immune responses, and pathogenesis of type 1 diabetes (T1D).

Methods: We aimed, using next-generation sequencing, to screen miRNAs from peripheral blood mononuclear cells of eight independent Kuwaiti-Arab families with T1D affected siblings, consisting of 18 T1D patients and 18 unaffected members, characterized by no parent-to-child inheritance pattern.

Results: Our analysis revealed 20 miRNAs that are differentially expressed in T1D patients compared with healthy controls.

ERAMER: A novel in silico tool for prediction of ERAP1 enzyme trimming.

MHC class I pathway consists of four main steps: proteasomal cleavage in the cytosol in which precursor proteins are cleaved into smaller peptides, which are then transported into the endoplasmic reticulum by the transporter associated with antigen processing, TAP, for further processing (trimming) from the N-terminal region by an ER resident aminopeptidases 1 (ERAP1) enzyme, to generate optimal peptides (8-10 amino acids in length) to produce a stable MHCI-peptide complex, that get transited via the Golgi apparatus to the cell surface for presentation to the cellular immune system. Several studies reported specificities related to the ERAP1 trimming process, yet there is no in silico tool for the prediction of the trimming process of the ERAP1 enzyme. In this paper, we provide and implement a prediction model for the trimming process of the ERAP1 enzyme.

Impact of the SARS-CoV-2 pandemic on the overall respiratory viruses' transmission in a cancer care setting.

Introduction And Objective: The emergence of the COVID-19 pandemic raised questions about the interaction between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other respiratory viruses. The objective of this study is to validate the impact of the SARS-CoV-2 pandemic and its interventional measures on the respiratory viruses' transmission/infection rates.

Methods: A retrospective chart review was conducted for cancer patients who underwent laboratory-confirmed respiratory virus polymerase chain reaction (PCR) testing from January 2018 to June 2022.

The Proinflammatory Role of ANGPTL8 R59W Variant in Modulating Inflammation through NF-κB Signaling Pathway under TNFα Stimulation.

Background: Angiopoietin-like protein 8 (ANGPTL8) is known to regulate lipid metabolism and inflammation. It interacts with ANGPTL3 and ANGPTL4 to regulate lipoprotein lipase (LPL) activity and with IKK to modulate NF-κB activity. Further, a single nucleotide polymorphism (SNP) leading to the ANGPTL8 R59W variant associates with reduced low-density lipoprotein/high-density lipoprotein (LDL/HDL) and increased fasting blood glucose (FBG) in Hispanic and Arab individuals, respectively.
