TATA box-based analysis reveals activation of growth programs in bladder cancer cells despite ferroptosis activation

Fernandez, M. A.Open in Google Scholar•Armisen, R.Open in Google Scholar•Fernandez, M. I.Open in Google Scholar

A poorly studied mechanism suggests that growth is characterized by the expression of TATA-less genes under favorable conditions, while stress induces TATA-containing genes involved in stress responses. The role of this mechanism in cancer remains unclear. This study analyzes the presence of TATA boxes in gene expression data from bladder cancer (BC) cells undergoing ferroptosis (siUSP52 cells), a form of programmed cell death. We hypothesize that growth-related genes (TATA-less) are underrepresented in siUSP52 cells. We found a high prevalence of TATA-less genes in siUSP52 cells (62 of 90 differentially expressed), suggesting that BC promotes growth despite ferroptosis activation.

Improving Differential Expression and Survival Analyses with Sample Specific Compartment Deconvolution.
Motivation: Studies on bulk RNA-seq of tumor biopsies can yield incorrect results because varying proportions of non-tumor tissues in the samples obscure the true signal and impact the accuracy of survival and differential expression analyses. Single-cell sequencing avoids these problems, but is still too expensive in clinical settings. Other deconvolution algorithms extract tissue-specific gene e...

Tumor-Educated-Platelets interact with Breast Cancer-Stem-Cells via P-selectin- PSGL1 and ensure stemness and metastasis through WNT-β-Catenin-VEGF-VEGFR2 intra-cellular signaling: Therapeutic modulation by aspirin
Background: Protagonistic role of platelets promote capillary infiltration of tumors for distant metastasis along with immunosurveillance. Despite existing reports highlighting role of platelets in tumorigenesis, its impact on breast cancer stem cells (BCSCs) remain underexplored. Our first ever report on murine and human system, accentuate that, tumor educated platelets (TEPs) of luminal A and TN...

Paracrine Signals from HIV-1 Infected Immune Cells Reprogram Cervical Cancer Pathways
Persistent infection with human papillomavirus (HPV) is the primary cause of cervical cancer worldwide. Notably, women co-infected with HPV and human immunodeficiency virus type 1 (HIV-1) have a six-fold higher lifetime risk of developing cervical cancer compared to those without HIV, even when adhering to antiretroviral therapy (ART) and achieving T-cell reconstitution. While chronic HIV-1 infect...

Breast Cancer Clustering Integrating Complete Gene Expression Profiles and Genetic Ancestry
Breast cancer (BC) remains the leading cause of cancer-related mortality among women globally. Precise subtyping of BC is critical for optimizing treatment strategies. This study explored the capacity of bulk RNA-seq data to improve breast cancer characterization by analysis of complete expression profiles. We analyzed RNA-seq 274 tumor samples and six healthy tissue samples from diverse geographi...

Optimising Chemotherapy for Locally Advanced High-Grade Serous Ovarian Cancer via Delay-Differential Equations
Ovarian cancer is the deadliest gynaecological cancer and the fourth leading cause of cancer deaths in women. High-grade serous ovarian cancer (HGSOC) accounts for 75% of cases, and chemotherapy resistance and relapse occur in 85% of patients, leading to a 5-year survival of 45%. Currently, the literature lacks comprehensive immunobiological models of HGSOC, and developing such models could provid...

Dietary lipids, not ketone body metabolites, influence intestinal tumorigenesis in a ketogenic diet
Diet composition shapes tissue function and disease risk by modulating nutrient availability, metabolic state, and cellular dynamics. In the gastrointestinal tract, obesogenic high-fat diets enhance intestinal stem cell activity and tumorigenesis. However, the impact of ketogenic diets (KD), which contain even higher lipid content but induce ketogenesis, remains poorly understood. This is particul...

Pancreatic cancer cachexia is mediated by PTHrP-driven disruption of adipose de novo lipogenesis
Pancreatic cancer patients have the highest rates and most severe forms of cancer cachexia, yet cachexia etiologies remain largely elusive, leading to a lack of effective intervening therapies. PTHrP has been clinically implicated as a putative regulator of cachexia, with serum PTHrP levels correlating with increased weight loss in PDAC patients. Here we show that cachectic PDAC patients have high...

A multi-step immune-competent genetic mouse model reveals phenotypic plasticity in uveal melanoma
Uveal melanoma (UM) is a highly aggressive intraocular malignancy with limited therapeutic options for metastatic disease. Existing transgenic UM mouse models inadequately recapitulate human disease progression, while transplant models lack immune competence for studying the tumor immune microenvironment and therapeutic interventions. To address these limitations, we developed a genetically engine...

Integrative analysis of mRNA stability regulation uncovers a metastasis-suppressive program in breast cancer
Heterogeneity in cancer gene expression is typically linked to genetic and epigenetic alterations, yet post-transcriptional regulation likely influences these patterns as well. However, the quantitative contribution of post-transcriptional mechanisms to cancer transcriptome dynamics remains unclear. Here, we systematically measured mRNA dynamics across diverse breast cancer models, revealing that ...
