Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

EL DISEÑO P.P.T. CON VARIABLES CATEGÓRICAS PARA LA ESTIMACIÓN DE DICO–RAZONES EL DISEÑO P.P.T. CON VARIABLES CATEGÓRICAS PARA LA ESTIMACIÓN DE DICO–RAZONES

open access: yesRevista Colombiana de Estadística, 2005
In probability proportional-to-size designs (P.P.S.) the selection probabilities that minimize the approximate variance of a totals ratio for dichotomic variables - dicho–ratio are found and their efficiency is compared with respect to S.I.

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

open access: yesMolecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Metodología para la estimación de dico-razones con el uso de información auxiliar en tablas de contingencia 3 × 3

open access: yesRevista Colombiana de Estadística, 2005
Se comparan los diseños M.A.S, P.P.T., ESTMAS y estratificado por el método de Hidiroglou para estimar una razón de totales de variables dicotómicas. En el diseño P.P.T. se muestran las probabilidades de selección que hacen mínima la varianza aproximada.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

DICO–RATIO ESTIMATION WITH AUXILIARY INFORMATION IN 3×3 CONTINGENCY TABLES METODOLOGÍA PARA LA ESTIMACIÓN DE DICO–RAZONES CON EL USO DE INFORMACIÓN AUXILIAR EN TABLAS DE CONTINGENCIA 3 × 3

open access: yesRevista Colombiana de Estadística, 2005
The S.I, P.P.S, STSI and stratified by the Hidiroglou’s method to estímate a totals ratio of dichotomic variables are compared. In the P.P.S. design the selection probabilities that make minimum the approximate variance are showed. In the STSI design, in

Effective therapeutic targeting of CTNNB1‐mutant hepatoblastoma with WNTinib

open access: yesMolecular Oncology, EarlyView.
WNTinib, a Wnt/CTNNB1 inhibitor, was tested in hepatoblastoma (HB) experimental models. It delayed tumor growth and improved survival in CTNNB1‐mutant in vivo models. In organoids, WNTinib outperformed cisplatin and showed enhanced efficacy in combination therapy, supporting its potential as a targeted treatment for CTNNB1‐mutated HB.

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

open access: yesMolecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.
