Irisin Attenuates Pulmonary Vascular Remodeling in Pulmonary Arterial Hypertension via Ubiquitin‐Mediated Regulation of ENO1

open access: yesAdvanced Science, EarlyView.
Irisin is a crucial plasma biomarker and promising therapeutic target that reflects disease severity, pulmonary vascular remodeling status and clinical outcome in patients with pulmonary arterial hypertension (PAH). As a novel protective factor, irisin is downregulated in PAH. By ubiquitination, irisin promotes Enolase 1 degradation and suppresses cell

RELA Ablation Contributes to Progression of Hepatocellular Carcinoma with TP53R249S Mutation and is a Potential Therapeutic Target

open access: yesAdvanced Science, EarlyView.
Genome‐wide CRISPR/Cas9 based screening identified RELA as a key tumor suppressor in TP53R249S‐mutant HCC. Its loss promotes tumorigenesis and metastasis via DVL1‐mediated Wnt/β‐catenin activation, while its agonist betulinic acid suppresses tumor progression.

The Evolutionary Trajectory and Prognostic Value of GITR+ Tregs Reprogramed by Tumor‐Intrinsic PD‐1/c‐MET Signaling in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
In pancreatic ductal adenocarcinoma (PDAC), tumor‐intrinsic PD‐1 signaling activates the MET pathway, leading to the establishment of an immunosuppressive tumor microenvironment (TME). This MET‐driven signaling cascade promotes the selective accumulation of GITR+ regulatory T cells (Tregs), a highly immunosuppressive subset.

The CXCL10‐CXCR3 Axis Induces Tumor‐Associated Neutrophils to Interfere with CTLs‐Mediated Antitumor Activity in EBV‐Associated Epithelial Cancers

open access: yesAdvanced Science, EarlyView.
Compared with EBV‐negative epithelial cancer cells, EBV‐associated epithelial cancer cells exhibit enhanced secretion of chemokines, including CXCL10 and CCL5, to attract neutrophils. Via the CXCL10‐CXCR3 axis‐mediated positive feedback loop, neutrophils within EBV‐associated epithelial cancer cells are induced to form abundant NETs, which facilitate ...

MALMPS: A Machine Learning‐Based Metabolic Gene Prognostic Signature for Stratifying Clinical Outcomes and Molecular Heterogeneity in Stage II/III Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
Chen et al. identified a metabolic gene prognostic signature with machine‐learning framework and assessed the prognostic value in independent CRC cohorts. The metabolic signature subtypes are characterized by specific metabolic and proteomic characteristics, and associated with distinct molecular pathway and therapeutic potential.

RPL6 Interacts with HMGCS1 to Stabilize HIF‐1α by Promoting Cholesterol Production in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
The study found that RPL6 is frequently upregulated in HCC tissues with extrahepatic metastasis. Elevated RPL6 bound to and increased the stability of HMGCS1 mRNA, thereby enhancing intracellular cholesterol levels. Subsequently, increased cholesterol promotes cancer metastasis in HCC by stabilizing HIF‐1α protein.

Estimability in Cox models

Statistical Papers, 2016
Our procedure of estimating is the maximum partial likelihood estimate (MPLE) which is the appropriate estimate in the Cox model with a general censoring distribution, covariates $$\mathbf {X}$$ and an ...

The Cox Model

2000
The Cox proportional hazards model [36] has become by a wide margin the most used procedure for modeling the relationship of covariates to a survival or other censored outcome.

An Extension of Cox's Regression Model

International Statistical Review / Revue Internationale de Statistique, 1983
Summary It is shown how one can construct a model for a jump process depending on an arbitrary intensity measure with the property that if the measure is absolutely continuous it reduces to Cox's regression model for survival data. The model has the property that the maximum likelihood estimator of the parameters are Cox's estimate for the regression ...

Subgroup analysis in the heterogeneous Cox model

Statistics in Medicine, 2020
In the analysis of censored survival data, to avoid a biased inference of treatment effects on the hazard function of the survival time, it is important to consider the treatment heterogeneity. Without requiring any prior knowledge about the subgroup structure, we propose a data driven subgroup analysis procedure for the heterogeneous Cox model by ...
