Targeting SETDB1 in cancer and immune regulation: Potential therapeutic strategies in cancer.

SET domain bifurcated histone lysine methyltransferase 1 (SETDB1/ESET), a pivotal H3K9 methyltransferase, has been extensively studied since its discovery over two decades ago. SETDB1 plays critical roles in immune regulation, including B cell maturation, T-cell activity modulation, and endogenous retrovirus (ERV) silencing. While essential for normal immune cell function, SETDB1 overexpression in cancer cells disrupts immune responses by suppressing tumor immunogenicity and facilitating immune evasion.

The Association Between Body Composition, Overall Survival, Treatment Decisions, and Patient-Reported Outcomes in Metastatic Non-Small-Cell Lung Cancer.

Introduction: The purpose of this study was to evaluate the association between body composition, overall survival, odds of receiving treatment, and patient-reported outcomes (PROs) in individuals living with metastatic non-small-cell lung cancer (mNSCLC).

Methods: This retrospective analysis was conducted in newly diagnosed patients with mNSCLC who had computed-tomography (CT) scans and completed PRO questionnaires close to metastatic diagnosis date. Cox proportional hazard models and logistic regression evaluated overall survival and odds of receiving treatment, respectively.

Cumulative Social Disadvantage and Medicinal Cannabis Use Among Younger Adults in Rural Communities: A Mixed Methods Approach.

This mixed-methods study investigated the role of medicinal cannabis use among younger adults who live in rural communities and experience high levels of cumulative social disadvantage (CSD). Results are based on cross-sectional surveys and online interviews with 153 younger adults (18-35-years old) in rural California. We assessed participants' levels of CSD (high, medium, and low) and examined associations with perceived general physical and mental health and with medicinal use of cannabis (MUC).

Sorafenib Alters Interstitial Proton and Sodium Levels in the Tumor Microenvironment: A H/Na Spectroscopic Imaging Study.

Cellular metabolism is inextricably linked to transmembrane levels of proton (H), sodium (Na), and potassium (K) ions. Although reduced sodium-potassium pump (Na-K ATPase) activity in tumors directly disturbs transmembrane Na and K levels, this dysfunction is a result of upregulated aerobic glycolysis generating excessive cytosolic H (and lactate) which are extruded to acidify the interstitial space. These oncogene-directed metabolic changes, affecting intracellular Na and H, can be further exacerbated by upregulation of ion exchangers/transporters.

Birth weight and prepubertal growth trajectory had a combined effect on pubertal initiation in girls.

Aim: Most studies of prepubertal weight and puberty have not used continuous or long follow-up periods. We explored the effect that birth weight and growth trajectories from 0-9 years of age had on starting puberty.

Methods: Data were obtained from 1510 children in Tianjin, China, who were born in 2013 and selected by cluster random sampling.

FMT reduces systemic inflammatory response in severe acute pancreatitis by increasing the abundance of intestinal and fecal bacteria.

Severe acute pancreatitis (SAP) is one of the leading causes of hospital admissions for gastrointestinal diseases, with a rising incidence worldwide. Intestinal microbiota dysbiosis caused by SAP exacerbates systemic inflammatory response syndrome and organ dysfunction. Fecal microbiota transplantation (FMT) has emerged as a promising therapeutic option for gastrointestinal diseases.

Vps4a Mediates a Unified Membrane Repair Machinery to Attenuate Ischemia/Reperfusion Injury.

Background: Cardiac ischemia/reperfusion disrupts plasma membrane integrity and induces various types of programmed cell death. The ESCRT (endosomal sorting complex required for transport) proteins, particularly AAA-ATPase Vps4a (vacuolar protein sorting 4a), play an essential role in the surveillance of membrane integrity. However, the role of ESCRT proteins in the context of cardiac injury remains unclear.

Filamin A C-terminal fragment modulates Orai1 expression by inhibition of protein degradation.

Filamin A (FLNA) is an actin-binding protein that has been reported to interact with STIM1 modulating the activation of Orai1 channels. Cleaving of FLNA by calpain leads to a C-terminal fragment that is involved in a variety of functional and pathological events, including pro-oncogenic activity in different types of cancer. Here we show that full-length FLNA is downregulated in samples from colon cancer patients as well as in the adenocarcinoma cell line HT-29.

Anchorage Accurately Assembles Anchor-Flanked Synthetic Long Reads.

Modern sequencing technologies allow for the addition of short-sequence tags, known as anchors, to both ends of a captured molecule. Anchors are useful in assembling the full-length sequence of a captured molecule as they can be used to accurately determine the endpoints. One representative of such anchor-enabled technology is LoopSeq Solo, a synthetic long read (SLR) sequencing protocol.

Detection of neurologic changes in critically ill infants using deep learning on video data: a retrospective single center cohort study.

Background: Infant alertness and neurologic changes can reflect life-threatening pathology but are assessed by physical exam, which can be intermittent and subjective. Reliable, continuous methods are needed. We hypothesized that our computer vision method to track movement, pose artificial intelligence (AI), could predict neurologic changes in the neonatal intensive care unit (NICU).

Using visual storytelling to share aggregate findings with families participating in clinical genomics research.

Purpose: Sharing aggregate results with research participants is a widely agreed-upon ethical obligation; yet, there is little research on communicating study results to diverse populations enrolled in genomics research. This article describes the cocreation of a visual narrative to explain research findings to families enrolled in a clinical genomics research study.

Methods: The design process involved researchers, clinicians, study participants, a physician illustrator, and a health communications expert.

Post-transcriptional regulation of the transcriptional apparatus in neuronal development.

Post-transcriptional mechanisms, such as alternative splicing and polyadenylation, are recognized as critical regulatory processes that increase transcriptomic and proteomic diversity. The advent of next-generation sequencing and whole-genome analyses has revealed that numerous transcription and epigenetic regulators, including transcription factors and histone-modifying enzymes, undergo alternative splicing, most notably in the nervous system. Given the complexity of regulatory processes in the brain, it is conceivable that many of these splice variants control different aspects of neuronal development.

Calorimetric measurement of energy and nutrient stimulation of microorganisms from the continental deep subsurface.

Microbial activity in the deep continental subsurface is difficult to measure due to low cell densities, low energy fluxes, cryptic elemental cycles and enigmatic metabolisms. Nonetheless, direct access to rare sample sites and sensitive laboratory measurements can be used to better understand the variables that govern microbial life underground. In this study, we sampled fluids from six boreholes at depths ranging from 244 m to 1,478 m below ground at the Sanford Underground Research Facility (SURF), a former goldmine in South Dakota, United States.

Evolution of community-associated MRSA: a 20-year genomic and epidemiological study in Region Örebro County, Sweden.

Background: Methicillin-resistant (MRSA) has been an issue in healthcare since the 1960s. It was initially found only in healthcare facilities, but in the late 1990s it began to be seen with no healthcare connexion. The mechanisms of intercontinental and national spread are not fully understood, as sometimes novel outbreaks occur without any identifiable source or connexion to locally dominant clonal clusters.

Inhibitory Effect of Human Anti-CA I Autoantibodies and Development of Monoclonal Antibody mAb 2B8 Targeting Carbonic Anhydrase I.

Spontaneous tumor regression is a recognized phenomenon across various cancer types. Recent research emphasizes the alterations in autoantibodies against carbonic anhydrase I (CA I) (anti-CA I) levels as potential prognostic markers for various malignancies. Particularly, autoantibodies targeting CA I and II appear to induce cellular damage by inhibiting their respective protein's catalytic functions.

Human iPSC-derived neural stem cells engraft and improve pathophysiology of MPS I mice.

Mucopolysaccharidosis type I (MPS I) is a metabolic disorder characterized by a deficiency in α-l-iduronidase (IDUA), leading to impaired glycosaminoglycan degradation. Current approved treatments seek to restore IDUA levels via enzyme replacement therapy (ERT) and/or hematopoietic stem cell transplantation (HSCT). The effectiveness of these treatment strategies in preventing neurodegeneration is limited due to the inability of ERT to penetrate the blood-brain barrier (BBB) and HSCT's limited CNS reconstitution of IDUA levels.

Mean Platelet Volume as an Emerging Biomarker for Diagnosing Acute Appendicitis: A Retrospective Study.

Introduction Acute appendicitis is a common surgical emergency that requires a timely and accurate diagnosis to prevent complications. Several laboratory markers have been assessed to improve the diagnostic accuracy of acute appendicitis, including C-reactive protein (CRP), white blood cell (WBC) count, and cytokines like interleukins and tumor necrosis factor-alpha. One less commonly used but potentially valuable marker is the mean platelet volume (MPV), which indicates the size of circulating platelets and has the potential to serve as a biomarker for inflammatory conditions.
