Colorectal cancer (CRC) is one of the most prevalent malignancies worldwide and the third leading cause of cancer-related fatalities. Long non-coding RNAs (lncRNAs) are key regulators of diverse physiological processes and are dysregulated in a wide range of pathophysiological circumstances such as CRC. Studies revealed that aberrant expressions of lncRNAs clearly modulate the expression level of p53 gene in CRC, thereby transactivating multiple downstream pathways.

is one of the leading causes of nosocomial infections, characterized by increasing antibiotic resistance, severity and mortality. Therefore, numerous efforts have been made nowadays to identify new therapeutic targets. This study aimed to find potential drug targets and vaccine candidates in drug-resistant strains of .

Colorectal cancer (CRC) is a common type of cancer and the second leading cause of cancer-related deaths worldwide. Competing endogenous RNAs (ceRNAs) that contain microRNA response elements (MREs) are involved in CRC progression. They can compete with microRNAs (miRNAs) via their MREs, which can combine non-coding and coding RNAs via complex ceRNA networks.

Unlabelled: Acute myeloid leukemia (AML) is a heterogeneous clonal disease that is considered to originate from hematopoietic stem cells, which are characterized by impaired myelopoiesis and blast proliferation. TET oncogene family member 2 (TET2) mutations are frequent in myeloid malignancies and several studies have assessed the clinical importance of TET2 mutations. However, its frequency ratio has not yet been fully clarified.

Background/aim: The KCNQ1 gene has a significant role in long QT syndrome, Jervell and Lange-Nielsen syndrome, familial atrial fibrillation, and short QT syndrome. Analyzing such heterogeneous disorders, six novel short tandem repeat (STR) markers around the KCNQ1 gene were found and evaluated in a healthy population, and other statistical traits of the markers were detected.

Materials And Methods: Using Tandem Repeats Finder (TRF) and Sequence-Based Estimation of Repeat Variability (SERV) software, STR markers were detected with valid tetra- and pentanucleotide repeats.

Article Synopsis
  • Long QT syndrome (LQTS) is a heart condition that can cause fainting and sudden death, primarily due to a prolonged QT interval, with the KCNQ1 gene being the most commonly associated.
  • A study conducted on Iranian families identified a new homozygous KCNQ1 mutation (c.1426_1429delATGC) through DNA sequencing and examined existing cases of LQTS.
  • This novel mutation is reported for the first time in the Iranian population, highlighting the significance of genetic research in identifying LQTS carriers.

Article Synopsis
  • Jervell-Lange Nielsen syndrome (JLNS) is a genetic disorder marked by hearing loss and a prolonged QT interval in heart rhythms, inherited in an autosomal recessive manner.
  • Researchers conducted genetic analysis on two unrelated Iranian families with syncope histories and identified a new mutation (c.733-734delGG) likely representing a common ancestor mutation in this population.
  • This discovery is significant as it is the first report of this mutation in Iranians and may aid in targeted genetic screenings for Long QT syndrome in the region.

Objectives: Jervell and Lange-Nielsen syndrome is an autosomal recessive disorder caused by mutations in KCNQ1 or KCNE1 genes. The disease is characterized by sensorineural hearing loss and long QT syndrome.

Materials And Methods: Here we present a 3.

Background: One of the foremost causes of sudden cardiac death in the young is an inherent cardiac arrhythmia known as Long-QT syndrome (LQTS). Whereas heterozygous mutations typically lead to the Romano-Ward type of LQTS, We have provided a further evidence for the recessive transmission of a novel KCNQ1 gene mutation in two consanguineous families for the first time in Iran.

Methods: Next generation sequencing, DNA Sanger sequencing and haplotype analysis were performed for genotype determination.

Background: Molecular human identification is one of the most important tests performed in forensic laboratories. Some of these tests are applied for identification of human remains from natural disasters, wars, etc., but problems may occur as a result of DNA degradation and external DNA contamination.
