Corticothalamic projections to sensorimotor thalamic nuclei show modest firing rates and serve to modulate the activity of thalamic relay neurons. By contrast, here we find that high-order corticothalamic projections from the prelimbic (PL) cortex to the anterior paraventricular thalamic nucleus (aPVT) maintain high-frequency activity and evoke strong synaptic excitation of aPVT neurons in rats. In a significant fraction of aPVT cells, such high-frequency excitation of PL-aPVT projections leads to a rapid decay of action potential amplitudes, followed by a depolarization block (DB) that strongly limits aPVT maximum firing rates, thereby regulating both defensive and appetitive behaviors in a frequency-dependent manner. …

Historically, CLL prognostication relied on disease burden, reflected in clinical stage. Later, chromosome abnormalities and genomics suggested several CLL subtypes which were aligned with response to therapy. Gene expression profiling data identified pathways associated with CLL progression. We hypothesized that transcriptome and proteome may identify functional omics associated with CLL nosology. As a test cohort, we utilized publicly available treatment-naïve CLL transcriptomics data (n = 130) and did consensus clustering that identified BTK-expression-based clusters. The BTK-High and BTK-Low clusters were validated in public and our in-house databases (n = >550 CLL patients). To associate with functional relevance, we took samples …

BACKGROUND: MECP2 Duplication Syndrome, also known as X-linked intellectual developmental disorder Lubs type (MRXSL; MIM: 300260), is a neurodevelopmental disorder caused by copy number gains spanning MECP2. Despite varying genomic rearrangement structures, including duplications and triplications, and a wide range of duplication sizes, no clear correlation exists between DNA rearrangement and clinical features. We had previously demonstrated that up to 38% of MRXSL families are characterized by complex genomic rearrangements (CGRs) of intermediate complexity (2 ≤ copy number variant breakpoints < 5), yet the impact of these genomic structures on regulation of gene expression and phenotypic manifestations have not been investigated.

METHODS: To study the role of the genomic rearrangement structures on an individual's clinical phenotypic variability, we employed a comprehensive …

Fetal and neonatal cardiac tumors are rare and often benign. Clinical presentation is primarily related to mass effect, pericardial effusion or arrhythmia. Prenatal detection can assist with risk assessment and inform optimal delivery plan and postnatal management. We report a fetus with a right atrial mass discovered in the third trimester. After successful surgical resection, pathology confirmed the mass to be a capillary-venous malformation, which are rare and challenging to diagnose. The true incidence of these vascular malformations within cardiac spaces is difficult to discern given the historic classification of numerous different vascular malformations under the umbrella term hemangioma.

Background/Objectives: Elephant endotheliotropic herpesvirus (EEHV) causes lethal hemorrhagic disease (HD) in Asian and African elephants in human care and the wild. It is the leading cause of death for young Asian elephants in North American and European zoos despite sensitive diagnostic tests and improved treatments. Thus, there is a critical need to develop an effective vaccine to prevent severe illness and reduce mortality from EEHV-HD. We generated a multi-antigenic EEHV mRNA vaccine to address this need that encodes the EEHV1A-subtype glycoproteins gB, gH, gL, and gO. These conserved proteins are the entry machinery for several herpesviruses in the betaherpesvirus subfamily …

Makara Journal of Science

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype characterized by the lack of estro-gen, progesterone, and human epidermal growth factor receptor 2 (HER2) receptors. TNBC cells are becoming more aggressive due to the high expression of manganese superoxide dismutase (MnSOD) antioxidants to suppress reactive oxygen species-induced apoptosis and promote oncogenic signaling. This study was aimed to evaluate the effects of MnSOD knockout (KO) on TNBC cell apoptosis by assessing the survivin, caspase-9, and caspase-3 expressions. BT-549 TNBC cells containing the clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9-edited MnSOD gene were used to evaluate the messenger RNA (mRNA) …

Therapeutic strategies targeting the DNA damage response, such as poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi), have revolutionized cancer treatment in tumors deficient in homologous recombination (HR). However, overcoming innate and acquired resistance to PARPi remains a significant challenge. Here, we employ a genome-wide CRISPR knockout screen and discover that the depletion of ubiquitin-activating enzyme E1 (UBA1) enhances sensitivity to PARPi in HR-proficient ovarian cancer cells. We show that silencing or pharmacological inhibition of UBA1 sensitizes multiple cell lines and organoid models to PARPi. Mechanistic studies uncover that UBA1 inhibition not only impedes HR repair to sensitize cells to PARP inhibition …

In this study, we evaluated KMT2A PTD in 1277 patients with hematological malignancies using optical genome mapping (OGM). KMT2A PTD was detected in 35 patients with acute myeloid leukemia (AML) (7%), 5 patients with myelodysplastic syndrome (MDS) (2.2%), and 5 patients with chronic myelomonocytic leukemia (CMML) (7.1%). The PTDs varied in size, region, and copy number. An Archer RNA fusion assay confirmed KMT2A PTD in all 25 patients tested: 15 spanning exons 2 to 8 and 10 spanning exons 2 to 10. Most patients …
