Summary: Intracellular calcium signaling regulates entosis through the SEPTIN-Orai1-Ca2+/CaM-MLCK-actomyosin axis. Orai1 calcium channels mediate intracellular calcium oscillations in entotic cells, and SEPTIN controls the polarized distribution of Orai1 for MLCK activation, resulting in actomyosin contraction and internalization of invasive cells. Calcium chelators and inhibitors of SEPTIN, Orai1, and MLCK can suppress entosis.

Summary: Penetration of immune cells into tumor cells through cell-in-cell (CIC) formation leads to in-cell killing of the host tumor cells, showing superior efficacy compared to canonical kiss-killing from outside. CD44 on tumor cells functions as a negative regulator of in-cell killing by inhibiting CIC formation. Antibody-mediated blockade of CD44 signaling enhances the suppressive effects of NK cells on tumor growth.

Summary: The study investigates the effects of CICs formation on tumor progression and found that tumor cells can acquire genetic information and malignant phenotypes from parental cells undergoing CICs formation. The derivatives from CICs displayed increased abilities in proliferation and invasiveness, indicating epithelial-mesenchymal transition. Whole exome sequencing analysis identified potential genes involved in CIC-mediated genetic transfer. These results suggest that CICs formation may promote genetic transfer and gain of malignancy during tumor progression.

Summary: Cancer is a major cause of illness and death worldwide. Colorectal cancer is the third most common cancer in men and the second most common in women. Standard antitumor therapies, such as cisplatin, have limitations due to their lack of specificity for tumor cells, drug resistance development, and severe side effects. Therefore, new methods and strategies for treating colorectal cancer are urgently needed. Current research focuses on novel platinum and other metal-based drugs, such as gold, silver, iridium, or ruthenium. Au(III) compounds are considered promising candidates for colorectal cancer treatment due to their structural similarity to Pt(II). However, their stability under physiological conditions needs improvement by combining with various ligands. This review summarizes the progress in developing stable Au(III) complexes with potential cytotoxic activity against cancer cells. Additionally, it highlights that the anticancer effects of Au derivatives are mediated by protein structures, such as thioredoxin reductase, rather than nucleic acids. The current state of in vivo studies is also discussed.

Summary: Inflammatory bowel diseases (IBD), such as Crohn's disease and ulcerative colitis, are global health problems with increasing frequency and unclear pathogenesis. Current treatment involves drugs like corticosteroids and derivative compounds, but more specific and effective therapies are desired. In this study, novel gold complexes were tested and found to have anti-inflammatory potential both in vitro and in vivo, particularly TGS 703, which was able to alleviate inflammation in a mouse model of colitis and showed a link to antioxidant systems. These findings suggest that gold(III) complexes may have therapeutic applications in the treatment of IBD.

Summary: Homotypic entosis is the process where one cancer cell invades and entirely engulfs a neighboring cancer cell within a vacuole. This study analyzed the frequency and characteristics of entotic figures in a case of breast cancer in different locations, including the primary tumor, regional lymph node, and distant metastasis. The majority of entotic figures were found in the lymph node, followed by the primary tumor and far metastasis. Notably, entosis did not result in cell death in any location, and altered morphology was observed in the far metastases. Additionally, the study proposed additional criteria for identifying pro-survival entotic structures in diagnostic histopathology.
