    Abstract Endogenous retroelements are DNA sequences which can duplicate and move to new locations in the genome. Actively moving endogenous retroelements can be disruptive to the host, and their expression is therefore often repressed. Interestingly, drugs that disrupt the repression of endogenous retroelements show promise for treating cancer. Expressed endogenous retroelements can activate innate immune receptors that activate the antiviral response, potentially leading to the death of cancer cells. We discuss disruptions to cellular processes which can lead to activation of the antiviral state from endogenous retroelements, and present the 'fire alarm hypothesis', where we argue that endogenous retroelements act as alarms for disruptions to these cellular processes. Furthermore, we discuss the properties of endogenous retroelements which make them suitable as alarms.

    Abstract Objective: The purpose of this study was to describe the management of 2 long-term users of cannabis with nutrition and psychotherapy.
    Clinical features: A 28-year-old man presented with a medical history of asthma, depression, anxiety, and smoking, and was a long-term user of cannabis for 9 years (usually 3 times a week). A 39-year-old man presented with a medical history of anxiety and fatigue, and was a long-term user of cannabis for 14 years (usually twice a week). Laboratory tests showed altered blood levels of homocysteine, vitamins, and cortisol.
    Intervention and outcome: Both patients were given supplements of vitamins (folic acid, methylcobalamin, and pyridoxine), vitamin D,
    Conclusion: This study describes vitamin deficiencies, low cortisol levels, and hyperhomocysteinemia in 2 cannabis users who were managed with a combination of nutritional supplements and psychotherapy.

    Abstract Introduction: Although pharmacological treatment for Attention-Deficit/Hyperactivity Disorder (ADHD) has demonstrated efficacy, several individuals persist in experiencing social and academic impairment. Additionally, the occurrence of significant side effects may render the use of psychotropic medications untenable. However, Transcranial Direct Current Stimulation (tDCS), a non-invasive brain stimulation technique, shows promising results in treating ADHD.
    Objectives: To investigate the efficacy and safety of tDCS on the performance of children and adolescents with ADHD in neuropsychological tests involving visual attention, visual and verbal working memory, and inhibitory control.
    Methodology: This study was a triple-blind, randomized, sham-controlled, crossover clinical trial. The intervention consisted of a daily session of tDCS (2 mA) or sham targeting the left dorsolateral prefrontal cortex (L-DLPFC), for 30 min, on five consecutive days. The primary outcome was change in the Visual Attention Test, Fourth Edition (TAVIS-4) before and after each intervention. Subjects were also evaluated pre and post-tDCS using the Digit Span subtest of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V), the Developmental Neuropsychological Assessment, Second Edition (NEPSY-II) Inhibiting Response (IR) subtest, and the Corsi Block-Tapping Task.
    Results: Fifteen individuals were included, and no statistically significant difference was observed when comparing the results of the TAVIS-4, the IR of NEPSY-II, and the intragroup Digit Span subtest of WISC-V undertaken before and after the procedure. Adverse events were mainly self-limiting and transient. The participants did not perceive any benefit from tDCS when measured on the Patient Global Impression of Improvement (PGI-I) Scale.
    Conclusion: This study did not meet its primary endpoint and found no performance enhancement in any investigated neuropsychological outcomes relating to the intervention group.

    Abstract Features of the cancer epigenome distinguish cancers from their respective cell of origin and establish therapeutic vulnerabilities that can be exploited through pharmacologic inhibition of DNA- or histone-modifying enzymes. Epigenetic therapies converge with cancer immunotherapies through "viral mimicry," a cellular state of active antiviral response triggered by endogenous nucleic acids often derived from aberrantly transcribed endogenous retrotransposons. This review describes the initial characterization and expansion of viral mimicry-inducing approaches as well as features that "prime" cancers for viral mimicry induction. Increased understanding of viral mimicry in therapeutic contexts suggests potential physiologic roles in cellular homeostasis. SIGNIFICANCE: Recent literature establishes elevated cytosolic double strand RNA (dsRNA) levels as a cancer-specific therapeutic vulnerability that can be elevated by viral mimicry-inducing therapies beyond tolerable thresholds to induce antiviral signaling and increase dependence on dsRNA stress responses mediated by ADAR1. Improved understanding of viral mimicry signaling and tolerance mechanisms reveals synergistic treatment combinations with epigenetic therapies that include inhibition of BCL2, ADAR1, and immune checkpoint blockade. Further characterization of viral mimicry tolerance may identify contexts that maximize efficacy of conventional cancer therapies.

    Abstract The appropriate coordination between epigenetic regulators is essential for spatial and temporal regulation of gene expression and maintenance of cell identity. Cancer is a disease driven by both genetic and epigenetic alterations. The widespread dysregulation and reversible nature of epigenetic alterations confer cancer cells with vulnerabilities for therapeutic interventions. Over the past decades, remarkable progress has been made in developing drugs that target epigenetic regulators, with many drugs under evaluation in clinical trials. Here, we summarize the epigenetic drugs currently in clinical investigations and highlight the potentials and challenges in their implication to treat cancer. We also discuss the preclinical and clinical results of combination therapies with epigenetic drugs and other therapies such as targeted and immune-based therapies.

    Abstract Genome-wide DNA methylation profiles of serous tubal intraepithelial carcinomas (STIC) resemble methylation profiles of high-grade serous ovarian carcinomas (HGSOC) more closely than normal fallopian tube epithelium. While STICs and HGSOCs share subsets of common hypermethylated regions, DNA methylation can distinguish STICs from HGSOCs to provide proof-of-principle that DNA methylation can identify HGSOC initiation.
