Limiting the Development of Anti-Cancer Drug Resistance in a Spatial Model of Micrometastases [PDF]

arXiv, 2016
While chemoresistance in primary tumors is well-studied, much less is known about the influence of systemic chemotherapy on the development of drug resistance at metastatic sites. In this work, we use a hybrid spatial model of tumor response to a DNA damaging drug to study how the development of chemoresistance in micrometastases depends on the drug ...

Advances in the Relationship between MicroRNA and Cisplatin Resistance 
of Lung Cancer

Chinese Journal of Lung Cancer, 2014
MicroRNAs (miRNAs) are a class of small, about 22 nucleotides endogenous noncoding RNAs that negatively regulate their target genes’ expression through post-transcriptional suppression.

Dissecting the Spatial and Single‐Cell Transcriptomic Architecture of Cancer Stem Cell Niche Driving Tumor Progression in Gastric Cancer

Advanced Science, EarlyView.
A single‐cell and spatial transcriptional atlas reveals the architecture of human gastric cancer stem cell (CSC) niche and the developmental trajectory of CSCs. These CSCs interact with immunosuppressive immune cells thereby constructing immune‐suppressive niche, and inflammatory cancer‐associated fibroblast (iCAFs) to enhance stemness through ...

KEAP1‐NRF2 protein–protein interaction inhibitors: Design, pharmacological properties and therapeutic potential

Medicinal Research Reviews, Volume 43, Issue 1, Page 237-287, January 2023., 2023
Abstract The transcription factor nuclear factor erythroid 2‐related factor 2 (NRF2) is considered the master regulator of the phase II antioxidant response. It controls a plethora of cytoprotective genes related to oxidative stress, inflammation, and protein homeostasis, among other processes.

How can we kill cancer cells: insights from the computational models of apoptosis [PDF]

arXiv, 2010
Cancer cells are widely known to be protected from apoptosis, which is a major hurdle to successful anti-cancer therapy. Over-expression of several anti-apoptotic proteins, or mutations in pro-apoptotic factors, has been recognized to confer such resistance.

Identification and Biological Evaluation of a Novel CLK4 Inhibitor Targeting Alternative Splicing in Pancreatic Cancer Using Structure‐Based Virtual Screening

Advanced Science, EarlyView.
Pancreatic cancer is a highly aggressive malignancy with limited treatment options. CLK4 regulates alternative splicing, contributing to cancer progression. This study establishes a computational model to identify CLK4 inhibitors, leading to compound 150441 (IC50: 21.4 nm).

NEK6 dampens FOXO3 nuclear translocation to stabilize C-MYC and promotes subsequent de novo purine synthesis to support ovarian cancer chemoresistance

Cell Death and Disease
De novo purine synthesis metabolism plays a crucial role in tumor cell survival and malignant progression. However, the specific impact of this metabolic pathway on chemoresistance in ovarian cancer remains unclear.

Halofuginone Disrupted Collagen Deposition via mTOR‐eIF2α‐ATF4 Axis to Enhance Chemosensitivity in Ovarian Cancer

Advanced Science, EarlyView.
COL1A1, a major component of ECM, contributes to chemoresistance and poor prognosis in ovarian cancer. Halofuginone (HF) attenuates CAF‐secreted COL1A1 through mTOR‐eIF2α‐ATF4 axis. Notably, HF disrupts collagen deposition to form the looser ECM and facilitates CD8+ T cell infiltration, partially via M2‐M1 macrophage polarization to enhance ...

Long noncoding RNA MALAT1 regulates autophagy associated chemoresistance via miR-23b-3p sequestration in gastric cancer

Molecular Cancer, 2017
Background Chemoresistance has long been recognized as a major obstacle in cancer therapy. Clarifying the underlying mechanism of chemoresistance would result in novel strategies to improve patient’s response to chemotherapeutics.

Stochastic modeling of phenotypic switching and chemoresistance in cancer cell populations [PDF]

arXiv, 2019
Phenotypic heterogeneity in cancer cells is widely observed and is often linked to drug resistance. In several cases, such heterogeneity in drug sensitivity of tumors is driven by stochastic and reversible acquisition of a drug tolerant phenotype by individual cells even in an isogenic population.
