TJ Cancer Research Results

TJ, Tight junctions: Click to Expand ⟱
Source: HalifaxProj(promote)
Type:
Tight junctions (TJ) are specialized structures that form a barrier between epithelial cells, regulating the passage of substances between the cells and maintaining the integrity of tissue. They play a crucial role in maintaining cell polarity, tissue homeostasis, and the selective permeability of epithelial layers.

1.Overexpression of some claudins (e.g., claudin-1, -3, -4) in certain cancers is often associated with increased tumor aggressiveness and poor prognosis (protumor effects).
2.Downregulation or mislocalization of occludin and ZO proteins is generally linked to loss of cell–cell adhesion, EMT, and worse outcomes.
3.In contrast, loss of claudin-7 can remove its tumor suppressor functions, thereby facilitating invasion.

The expression and impact of tight junction components in cancer is an area of active research—each protein can have dual roles (protumor or tumor suppressive) based on the tumor type, the molecular context, and the stage of disease progression.

6000- Chit,    Chitosan in Modern Pharmacotherapy: From Drug Encapsulation to Targeted Delivery Systems
- Review, Var, NA
DDS↑, ecent scientific research demonstrates that chitosan represents a valuable candidate for designing non-invasive drug delivery strategies.
toxicity↓, Chitosan nanoparticles are capable of optimizing drug pharmacokinetics, increasing local drug concentrations, and reducing overall systemic toxicity.
TJ↓, Its positively charged amino groups give it unique properties, including mucoadhesion, the ability to open epithelial tight junctions, and strong interactions with negativelycharged biological membranes, which helps increase the bioavailability of d

other↝, Chitosan nanoparticles are most commonly produced via ionotropic gelation, where positively charged amino groups interact with multivalent anions, such as tripolyphosphate (TPP).
eff↑, Chitosan-based hydrogels can be adapted to respond to physiological stimuli, especially changes in pH.
eff↑, acidic tumor microenvironments, pH-sensitive chitosan releases drugs, while under redox conditions with elevated GSH levels, carriers disintegrate, ensuring intracellular drug delivery

6108- Chol,    Trimethylamine-N-Oxide (TMAO) as a Rising-Star Metabolite: Implications for Human Health
- Review, Nor, NA - Review, AD, NA
*TMAO↑, The gut microbiota’s role in metabolizing phytoestrogens suggests that these compounds can modulate the microbial community structure, potentially affecting the production of TMAO from dietary choline and carnitine [5].
*ROS↑, TMAO has the ability to induce oxidative stress in cells by promoting the production of reactive oxygen species (ROS).
*NADPH↑, TMAO has been shown to increase the activity of NADPH oxidase [30], an enzyme that generates ROS as part of its normal function.
*Ca+2↑, TMAO enters platelets and facilitates the release of calcium ions (Ca2+) from intracellular stores.
*AntiAg↓, Calcium serves as a critical secondary messenger in platelet activation, and its elevated levels promote platelet aggregation and thrombus formation
*cognitive↓, TMAO has been linked to cognitive decline and neurodegenerative disorders, including Alzheimer’s disease (AD). Through an integrated analysis of genetic, epigenetic, pathological, and biochemical data, Xu et al. identified a correlation between gut m
*TJ↓, However, excessive TMAO concentrations disrupt BBB integrity by inhibiting tight junction proteins, including claudin-5 and zonula occludens-1
*CLDN1↓,
*ZO-1↓,
*Inflam↑, TMAO also triggers neuroinflammation by activating the NLRP3 inflammasome,
*NLRP3↑,
*ER Stress↑, TMAO enhances the ER stress response by activating the PERK-eIF2α pathway, which is known to impair synaptic plasticity and neuronal function, processes strongly implicated in AD progression
*cognitive↓, TMAO has been identified as the most predictive biomarker for memory impairment and cognitive decline among 56 microbiota-derived metabolic markers
*Dose↝, use of cooking methods such as boiling or stewing instead of grilling, which can produce higher amounts of TMAO
*eff↑, Studies suggest that Lactobacillus plantarum ZDY04 could help reduce TMAO concentrations and prevent TMAO-induced atherosclerosis in animal models
*other↝, Currently, no medications specifically designed to reduce blood TMAO levels exist
*other↝, a review published in 2025 has highlighted the potential role of statins in lowering TMAO levels independently of their cholesterol-lowering effects
*other↝, scientific evidence suggests that statins selectively inhibit the growth of pathogenic bacteria, such as Clostridium and Ruminococcus, while promoting beneficial species, such as Bifidobacterium and Lactobacillus
