Background: Berberine is an active compound found in different herbs used in Chinese medicine and is well-known for its potential anticancer properties. The study aimed to figure out the role of berberine in regulating the malignant behavior of laryngeal squamous cell carcinoma (LSCC) cells.
Methods: LSCC cell lines (SNU-899 and AMC-HN-8) were treated with different concentrations of berberine (0-200 μM) to determine its cytotoxicity. The migration, invasion, and apoptosis of LSCC cells were measured by wound healing assays, Transwell assays, and flow cytometry. Western blot was performed for the quantification of proteins involved in PI3K/AKT/mTOR signaling.
Results: The viability of LSCC cells was dose-dependently reduced by berberine. Berberine dampened LSCC cell migration and invasion while augmenting cell apoptosis, as evidenced by a reduced wound closure rate, a decrease in invaded cell number, and a surge in cell apoptosis in the context of berberine stimulation. Importantly, the effects of berberine on the cancer cell process were enhanced by LY294002 (an inhibitor for PI3K) treatment. Moreover, the protein levels of phosphorylated PI3K, AKT, and mTOR were markedly reduced in response to berberine treatment.
Conclusion: Berberine inhibits cell viability, migration, and invasion but augments cell apoptosis by inactivating PI3K/AKT/mTOR signaling in LSCC.

Collective migration of cancer cells is often interpreted using concepts derived from the physics of active matter, but the experimental evidence is mostly restricted to observations made in vitro. Here, we study collective invasion of metastatic cancer cells injected into the mouse deep dermis using intravital multiphoton microscopy combined with a skin window technique and three-dimensional quantitative image analysis. We observe a multicellular but low-cohesive migration mode characterized by rotational patterns which self-organize into antiparallel persistent tracks with orientational nematic order.

Preeclampsia is characterized by insufficient invasion of extravillous trophoblasts and is a consequence of failed adaption of extravillous trophoblasts to changes in the intrauterine environment developing embryo. Specific miRNAs are implicated in the development of preeclampsia (PE). miR-455-5p is present at low levels in PE but its role is not known.

MTDH-SND1 protein-protein interaction (PPI) plays an important role in the initiation and development of tumors, and it is a target for the treatment of breast cancer. In this study, we identified and synthesized a series of novel small-molecule inhibitors of MTDH-SND1 PPI. The representative compound showed potent activity against MTDH-SND1 PPI with an IC of 487 ± 99 nM and tight binding to the SND1-purified protein with a value of 279 ± 17 nM.

Transfer RNA-derived small RNAs (tsRNAs), a recently identified non-coding RNA subset, are mainly classified into tRNA-derived small RNA fragments (tRFs) and tRNA-derived stress-induced RNAs (tiRNAs). tsRNAs dysregulation is frequently observed in numerous cancer types, suggesting involvement in tumorigenesis. However, their functions in breast cancer (BC) remain to be fully understood.
