Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy, yet most patients fail to achieve durable responses. To better understand the tumor microenvironment (TME), we analyze single-cell RNA-seq (~189 K cells) from 36 metastatic melanoma samples, defining 14 cell types, 55 subtypes, and 15 transcriptional hallmarks of malignant cells. Correlations between cell subtype proportions reveal six distinct clusters, with a mature dendritic cell subtype enriched in immunoregulatory molecules (mregDC) linked to naive T and B cells. Importantly, mregDC abundance predicts progression-free survival (PFS) with ICIs and other therapies, especially when combined with the TCF7 + /- CD8 T cell ratio. Analysis …

Mechanisms Underlying Treatment-Resistant Depression: Exploring Sex-Based Biological Differences, Francisco E R Da Silva, Atakan Yucel, Antonio P M Menezes, Ana C Ruiz, Marcela C Carbajal Tamez, Tatiana Barichello, Giselli Scaini, Joao Quevedo

Faculty, Staff and Student Publications

Treatment-resistant depression (TRD) represents a severe and complex subtype of major depressive disorder (MDD), affecting approximately 30% of patients who fail to respond adequately to multiple standard antidepressant therapies. While the pathophysiology of TRD remains incompletely understood, emerging evidence suggests that sex-based biological differences might influence its onset, progression, and treatment response. Women are disproportionately affected by depression and are more likely to experience residual symptoms and treatment resistance, potentially due to hormonal fluctuations, immune system differences, and variations in brain circuitry and neuroplasticity. This narrative explores the current literature on the mechanisms underlying TRD, with a particular emphasis on …

Heightened Risk: Childhood Trauma And Anticipatory Grief Exacerbate The Impact Of Loneliness On Depressive Symptoms And Lps-Stimulated Cytokines In Dementia Caregivers, Kelly N Brice, Jensine Paoletti-Hatcher, E Lydia Wu-Chung, Vincent D Lai, Daniel L Argueta, Michelle A Chen, Itee Mahant, Bryan T Denny, Charles Green, Luis D Medina, Paul Schulz, Jennifer Stinson, Samantha K Henry, Cobi Heijnen, Christopher P Fagundes

Dementia spousal caregivers are at a disproportionate risk for adverse mental and physical health outcomes. Loneliness is associated with depressive symptoms and proinflammatory cytokine production among caregivers. Additionally, childhood trauma, anticipatory grief, and poor sleep quality are all associated with enhanced stress reactivity. This study used a cross-sectional design to investigate whether loneliness is associated with proinflammatory cytokine production and depressive symptoms in caregivers, and whether these relationships are strongest among caregivers who report high levels of childhood trauma, high amounts of anticipatory grief, or poor sleep quality. A sample of 111 dementia spousal caregivers provided blood samples and completed …

Alzheimer's disease (AD), pathologically characterized by misfolding and accumulation of amyloid beta (Aβ) and hyperphosphorylated tau, is the leading cause of neurodegenerative dementia, accounting for 60-80 % of cases. The familial form of AD is caused by mutations in amyloid precursor protein (APP), presenilin-1 (PSEN1), and presenilin-2 (PSEN2) genes. Here, we report the generation of an iPSC line from a 39-year-old AD patient carrying a missense mutation in PSEN1 (F177S), leading to very early onset of AD. The patient also carries a rare variant Q49E in the microtubule-associated protein tau gene (MAPT) with an as yet unknown clinical significance.

Immunosuppressive myeloid cells are important in a variety of physiological and pathological contexts, including tumor development, but how hormones might regulate their activity is unclear. Secretogranins, a family of secretory proteins in endocrine and neuronal cells, are proposed to function as prohormones or hormones, but their specific receptors are unknown. Here we show that secretogranin 2 (SCG2), a granin family member, functionally interacts with leukocyte immunoglobulin-like receptor B4 (LILRB4) on monocytic cells. Tumor-derived SCG2 promotes tumor growth in myeloid-specific LILRB4 transgenic mice in a T cell-dependent manner, whereas SCG2 deficiency in host mice impairs tumor progression and reduces infiltration of …

Faculty, Staff and Student Publications

Peripartum depression (PPD) represents a significant public health concern, affecting 10-17% of women globally. Traditional monoaminergic treatments demonstrate limited efficacy and delayed onset of action. The glutamate-GABA imbalance hypothesis provides a novel theoretical framework for understanding depression pathophysiology and developing targeted therapeutic interventions. This review examines emerging pharmacotherapeutic approaches targeting glutamatergic and GABAergic neurotransmitter systems for PPD treatment. Search criteria targeted randomized clinical trials investigating GABA-A-positive allosteric modulators (brexanolone, zuranolone, and ganaxolone) and NMDA receptor antagonists (ketamine and esketamine) in PPD patients. Brexanolone was the first neurosteroid to receive FDA approval for PPD, while zuranolone also shows promise. Ketamine and …

Lymph node metastasis (LNM) is a critical prognostic factor for patients with oral squamous cell carcinoma (OSCC). Previous research has implicated the partial epithelial-to-mesenchymal transition of tumor cells and myofibroblastic cancer-associated fibroblasts (myCAFs) in the LNM process. However, the underlying molecular mechanisms remain poorly understood. Here, we conducted a comprehensive molecular analysis integrating original and publicly available OSCC data from bulk genome and transcriptome, single-cell transcriptome, and spatial transcriptome analyses. We found that myCAFs were quantitatively and functionally activated in LNM-positive samples and spatially colocalized with OSCC cells within the invasive tumor front (ITF), providing a niche that may facilitate …

Aberrant DNA methylation has been described in nearly all human cancers, yet its interplay with genomic alterations during tumor evolution is poorly understood. To explore this, we performed reduced representation bisulfite sequencing on 217 tumor and matched normal regions from 59 patients with non-small cell lung cancer from the TRACERx study to deconvolve tumor methylation. We developed two metrics for integrative evolutionary analysis with DNA and RNA sequencing data. Intratumoral methylation distance quantifies intratumor DNA methylation heterogeneity. MR/MN classifies genes based on the rate of hypermethylation at regulatory (MR) versus nonregulatory (MN) CpGs to identify driver genes exhibiting recurrent functional …

Transcription Factor Ybx1 Orchestrates Drug Resistance And Tumor Progression In Hcc, Dennis Kwabiah, Veerababu Nagati, Manish K. Tripathi

School of Medicine Publications

Drug resistance continues to be a significant challenge in cancer treatment, responsible for over 90% of worldwide cancer-related deaths. Transcription factors (TFs), which control vital cellular processes, also play a crucial role in cancer development and resistance. In hepatocellular carcinoma (HCC), resistance to sorafenib, a primary targeted therapy, significantly impairs treatment effectiveness and worsens patient outcomes. Among TFs, Y-box binding protein 1 (YBX1) has been recognized as a regulator of aggressive cancer traits in colorectal and breast cancers. However, its role in HCC and sorafenib resistance remains unclear. This review examines YBX1’s role in HCC progression and drug resistance, its …
