Prolonged Corrected QT Interval as an Early Electrocardiographic Marker of Cyclophosphamide‐Induced Cardiotoxicity in Pediatric Hematology and Oncology Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cyclophosphamide (CY) is associated with potentially fatal cardiotoxicity, yet no electrocardiographic indices have been established for early detection of CY‐induced cardiomyopathy. This study aimed to determine whether corrected QT interval (QTc) prolongation can predict early onset of CY‐related cardiac dysfunction in pediatric ...

Acute hypoxia induced dysregulation of clock-controlled ovary functions

Frontiers in Physiology, 2022
High altitudes or exposure to hypoxia leads to female reproductive disorders. Circadian clocks are intrinsic time-tracking systems that enable organisms to adapt to the Earth’s 24-h light/dark cycle, which can be entrained by other environmental stimuli ...

The transcriptional repressor complex FRS7-FRS12 regulates flowering time and growth in Arabidopsis [PDF]

, 2017
Most living organisms developed systems to efficiently time environmental changes. The plant-clock acts in coordination with external signals to generate output responses determining seasonal growth and flowering time.

Prognostic Impact of Treatment Modalities, Including Targeted Compartmental Radio‐Immunotherapy, in a Cohort of Neuroblastoma Patients With CNS Metastases at Relapse

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neuroblastoma (NB) with central nervous system (CNS) metastases is rare at diagnosis, but occurs more often during relapse/progression. Patients with CNS metastases face a dismal prognosis, with no standardized curative treatment available.

A simple method to measure CLOCK-BMAL1 DNA binding activity in tissue and cell extracts [version 2; referees: 2 approved, 1 approved with reservations]

F1000Research, 2017
The proteins CLOCK and BMAL1 form a heterodimeric transcription factor essential to circadian rhythms in mammals.  Daily rhythms of CLOCK-BMAL1 DNA binding activity are known to oscillate with target gene expression in vivo.

PSMD11 modulates circadian clock function through PER and CRY nuclear translocation.

PLoS ONE, 2023
The molecular circadian clock is regulated by a transcriptional translational feedback loop. However, the post-translational control mechanisms are less understood. The NRON complex is a large ribonucleoprotein complex, consisting of a lncRNA and several

Orchestrated transcription of biological processes in the marine picoeukaryote Ostreococcus exposed to light/dark cycles [PDF]

, 2010
Background: Picoeukaryotes represent an important, yet poorly characterized component of marine phytoplankton. The recent genome availability for two species of Ostreococcus and Micromonas has led to the emergence of picophytoplankton comparative ...

Pathogenic Germline PALB2 and RAD50 Variants in Patients With Relapsed Ewing Sarcoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Approximately 10% of patients with Ewing sarcoma (EwS) have pathogenic germline variants. Here, we report two cases: first, a novel germline pathogenic variant in partner and localizer of BRCA2 (PALB2) in a patient with a late EwS relapse. Its impact on homologous recombination is demonstrated, and breast cancer risk is discussed.

Correlation between circadian and photoperiodic latitudinal clines in Drosophila littoralis

Open Biology
Insects can survive harsh conditions, including Arctic winters, by entering a hormonally induced state of dormancy, known as diapause. Diapause is triggered by environmental cues such as shortening of the photoperiod (lengthening of the night).
