Optimal Therapy of Hepatitis C Dynamics and Sampling Based Analysis [PDF]

arXiv, 2011
We examine two models for hepatitis C viral (HCV) dynamics, one for monotherapy with interferon (IFN) and the other for combination therapy with IFN and ribavirin. Optimal therapy for both the models is determined using the steepest gradient method, by defining an objective functional which minimizes the infected hepatocyte levels, virion population ...

The transactivation potential of variant hepatocyte nuclear factor 1 is modified by alternative splicing.

Journal of Biological Chemistry, 1993
Two forms of the transcription factor vHNF1 (HNF1 beta or LFB3) have been previously described, derived by alternative splicing from a common premessenger RNA, and have been called vHNF1-A and vHNF1-B. vHNF1 proteins share a homologous homeo-related DNA-binding domain with the HNF1 protein, initially characterized as a liver-restricted transcription ...

TAK1-dependent autophagy: A suppressor of fatty liver disease and hepatic oncogenesis. [PDF]

, 2014
In addition to regulating the activation of nuclear factor (NF)-κB and c-Jun N-terminal kinase (JNK), TGF-β activated kinase 1 (TAK1) also upregulates the activation of AMP-activated protein kinase (AMPK) and autophagy.

Murine Models and Human Cell Line Models to Study Altered Dynamics of Ovarian Follicles in Polycystic Ovary Syndrome

Advanced Biology, EarlyView.
The manuscript examines preclinical murine and human models to study polycystic ovary syndrome (PCOS), delving into the cellular and molecular mechanisms underlying altered ovarian follicular dynamics. It explores the cellular interactions involved in normal and PCOS ovaries and outlines the current and novel strategies in the search for preclinical ...

Improved Progression-Free Survival in Irinotecan-Treated Metastatic Colorectal Cancer Patients Carrying the HNF1A Coding Variant p.I27L

Frontiers in Pharmacology, 2017
Hepatocyte nuclear factor 1-alpha (HNF1A) is a liver-enriched transcription factor that plays a key role in many aspects of hepatic functions including detoxification processes.

TRIB1 regulates liver regeneration by antagonizing the NRF2-mediated antioxidant response

Cell Death and Disease, 2023
Robust regenerative response post liver injuries facilitates the architectural and functional recovery of the liver. Intrahepatic redox homeostasis plays a key role in liver regeneration.

Three-dimensional cell culture model for hepatocytes opens a new avenue of real world research on liver [PDF]

arXiv, 2019
3-demensional (3D) culture model is a valuable in vitro tool to study liver biology, metabolism, organogenesis, tissue morphology, drug discovery and cell-based assays. Compelling evidence suggests that cells cultured in 3D model exhibit superior liver-specific functions over the conventional 2-dimentional (2D) culture in evaluating hepatobiliary drug ...

Tauroursodeoxycholic acid dampens oncogenic apoptosis induced by endoplasmic reticulum stress during hepatocarcinogen exposure [PDF]

, 2015
Hepatocellular carcinoma (HCC) is characterized by the accumulation of unfolded proteins in the endoplasmic reticulum (ER), which activates the unfolded protein response (UPR).

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Increased hepatic PDGF-AA signaling mediates liver insulin resistance in obesity associated type 2 diabetes [PDF]

arXiv, 2017
Type 2 diabetes (T2D) is closely linked with non-alcoholic fatty liver disease (NAFLD) and hepatic insulin resistance, but the involved mechanisms are still elusive. Using DNA methylome and transcriptome analyses of livers from obese individuals, we found that both hypomethylation at a CpG site in PDGFA (encoding platelet derived growth factor alpha ...
