Summary: The study found that GJA1 is significantly increased in HCCs and hepatic cirrhosis, and overexpressed in pulmonary metastases from HCCs. Overexpression of GJA1 promoted proliferation and migration of HSCs and HCC cells. The potential mechanism suggests that GJA1 promotes HCC progression by inducing HSC activation and EMT in HSCs and HCCLM3 cells.

Summary: Cholestatic liver diseases like PBC and PSC are associated with liver fibrogenesis, which can lead to cirrhosis. However, the relationship between liver fibrosis development and cholestatic liver disease progression remains unclear. Periductular fibroblasts differ biologically from hepatic stellate cells, and fibrotic events in these conditions are related to complex crosstalk between immune/inflammatory mechanisms, cytokine signaling, and disrupted homeostasis between cholangiocytes and mesenchymal cells.

Summary: This study demonstrates that Trimetazidine (TMZ) can inhibit liver fibrosis and hepatic stellate cell proliferation induced by CCl4 and TGF-beta. TMZ exerts its effects by blocking the activation of TGF beta/Smad signaling pathway. These findings provide new insights into the potential application of TMZ in the treatment of liver fibrosis.

Summary: This study found that BMI-1 is overexpressed in CRC liver metastasis and activates HSCs to secrete prometastatic factors, thereby creating a conducive environment for metastasis in the liver. In addition, HSCs also promote proliferation, migration, and EMT in CRC cells through the TGF-beta/SMAD pathway.

Summary: Liver fibrosis is a progressive and debilitating disease characterized by excessive deposition of extracellular matrix proteins. Our study reveals that KLF10 acts as a negative regulator of TGF-beta signaling pathway, suppressing hepatic stellate cell activation and fibrogenesis through modulation of ATF3 expression. Targeting the KLF10-ATF3 axis may have therapeutic implications for liver fibrosis treatment.

Summary: Non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and liver fibrosis are progressive liver diseases associated with metabolic syndrome. The elevated expression of TSC22D4 in patients with type 2 diabetes, NAFLD, and NASH suggests its involvement in the progression of these diseases. The study reveals that TSC22D4 contributes to the activation, proliferation, and migration of hepatic stellate cells (HSCs), implicating it as a key regulator in the development of liver fibrosis.

Summary: Hepatic deficiency of Vps33b exacerbates cholestatic liver injury, leading to abnormal serum markers and liver function, as well as altered metabolism of bile acids. Metabolomics analysis reveals that Vps33b deficiency changes the profile of bile acids, accompanied by alterations in gene expression of bile acid metabolizing enzymes and transporters.

Summary: Recurrence and metastasis are main challenges in CRC treatment, driven by a small subpopulation of cells called cancer stem-like cells (CSCs). Transcriptomic profiling showed upregulation of Wnt pathway and stemness genes in metastatic tumors, and treatment with small-molecule Wnt inhibitor ICG-001 effectively suppressed CSC behavior and metastasis.

Summary: This study highlights the important role of lipid rafts (LRs) in colorectal cancer, where an LR-disrupting alkylphospholipid drug can suppress CSC populations and their self-renewal activities. By inhibiting the LR/CHEK1 axis, the drug forces CSCs to enter inappropriate mitosis, leading to catastrophic cell death.

Summary: In this study, color conversion layers (CCLs) for full-color micro-LED display were successfully fabricated using a perovskite quantum dot (PQD)/siloxane composite. The PQD was ligand exchanged with a silane compound and then surface activated using a halide-anion containing salt, allowing non-polar organic solvents to be used without damaging the PQD. The ligand-exchanged PQD exhibited high dispersibility and excellent atmospheric stability in the siloxane matrix. The resulting full-color micro-LED display achieved a resolution of about 25.4 pixels per inch (PPI) with a 1 mm pixel pitch, and demonstrated the possibility of a flexible display that can be operated without damage even with a bending radius of 5 mm.

Summary: Autophagy has both pro-survival and pro-death functions in cancer, depending on the context. In this study, the researchers investigated the expression patterns of SNAREs, a family of proteins involved in autophagy, in colorectal cancer (CRC) tissues. They found that SEC22B, a vesicle SNARE, was highly expressed in tumor tissues, especially in metastatic tissues. Knocking down SEC22B inhibited CRC cell survival and growth, particularly under stressful conditions, and reduced the number of stress-induced autophagic vacuoles. Furthermore, SEC22B knockdown attenuated liver metastasis in a CRC cell xenograft mouse model. This study suggests that SEC22B plays a crucial role in enhancing the aggressiveness of CRC cells and may be a potential therapeutic target.

Summary: This study compared the thickness and gap width of thermoformed and 3D-printed clear aligners using micro-CT, and evaluated their translucency using spectrophotometer. The results showed that the translucency of the 3D-printed CAs varied depending on the cleaning methods, with the PC group having higher translucency than the PA group. Thermoformed CAs had a decrease in thickness after the manufacturing process, while 3D-printed CAs had an increase in thickness.

Summary: Tumors gain a competitive edge over intestinal stem cells by exploiting the self-renewal processes of the stem cells. The dynamics of stem cells in the intestines are regulated by a network of molecular signals and competition for limited space. The Wnt signaling pathway and its inhibitors play a crucial role in maintaining the balance between self-renewal and differentiation. Intestinal cancer cells bypass these regulatory mechanisms, allowing them to outcompete normal cells.

Summary: This study identifies a novel mechanism by which DCLK1 regulates the aggressiveness of colorectal cancer (CRC). The researchers found that DCLK1 binds and phosphorylates XRCC5, which leads to the activation of cyclooxygenase-2 and enhanced prostaglandin E2 production, resulting in an inflammatory tumor microenvironment and increased aggressiveness of CRC cells. The inhibition of DCLK1 kinase activity was shown to impair tumor seeding and growth in CRC mouse models. This study expands the understanding of the biological function of DCLK1 in CRC.

Summary: This study identified an increased expression of CD45 in CRC (EpCAM+) epithelial cells after CRT treatment. High CD45 expression promoted CRC cell survival upon 5-fluorouracil or radiation treatment, while CD45 depletion sensitized CRC cells to CRT. CD45 was found to be preferentially expressed in cancer stem-like cells (CSCs) and played a crucial role in CSC functions such as cancer initiation, repopulation, and metastasis.
