Summary: Sulforaphane (SFN), a natural compound derived from broccoli, has been found to significantly inhibit migration and invasion of breast cancer cells by affecting cytoskeleton formation. SFN can also directly bind to RAF family proteins and inhibit phosphorylation of the signaling pathway. These findings suggest that SFN has the potential to be used as a therapeutic drug to inhibit breast cancer cell metastasis.

Summary: RAF inhibitors unexpectedly activate ERK signaling in both normal and tumor cells with elevated RAS activity. This study demonstrates that RAF inhibitors can cause paradoxical ERK activation in KRAS(G12C)-dependent lung cancer cell lines. It also reveals that classical RAS proteins are not essential for this process, and the MRAS/SHOC2 complex plays a vital role.

Summary: Molecular target inhibitors have been approved for tumor treatment and mainly target cell proliferation and metabolism. The RAS-RAF-MEK-ERK pathway plays essential roles in cell functions and abnormal activation of this pathway leads to tumor development. In this review, the development and potential combinations of inhibitors targeting this pathway are discussed.

Summary: Autophagy is an intracellular recycling process that can be induced by leptin, a pro-tumorigenic protein, in cancer cell lines. Inhibition of autophagy reduces leptin-induced cell proliferation, migration, and ERK activation. This suggests a potential use for autophagy inhibition in breast cancer associated with obesity.

Summary: Resistance to breast cancer chemotherapy can be reversed by microRNA34a (miR34a). The combination of miR34a and Doxorubicin (Dox) significantly inhibits the proliferation, migration, invasion, and induces apoptosis of drug-resistant breast cancer cells. The mechanism involves the down-regulation of TOP2A and BCRP, as well as the inhibition of Snail through the Notch/NF-kappa B and RAS/RAF/MEK/ERK pathway.

Summary: The RAF-MEK-ERK signaling cascade is a well-characterized MAPK pathway that plays a critical role in cell proliferation and survival. Genetic alterations in this pathway are highly prevalent in human cancers and can lead to uncontrolled cell growth and tumor formation. The crosstalk between the RAF-MEK-ERK axis and other signaling pathways further enhances its proliferative potential in human cancers.

Summary: Despite advances in targeted therapy and immunotherapy, treating RAS mutant cancers remains challenging. These cancers have been found to activate adaptive resistance mechanisms like autophagy during MAPK inhibition. Recent focus has been on developing MAPK pathway and autophagy inhibitors for potential synthetic lethal approaches in cancer therapy, with ongoing clinical trials to evaluate their efficacy.

Summary: Despite efforts to improve treatment for cholangiocarcinoma, the long-term survival rate remains poor. HCQ, an antimalarial drug, inhibits autophagy and shows therapeutic effects on various cancers. In this study, HCQ effectively suppressed cholangiocarcinoma by inhibiting autophagy, inducing apoptosis and cell cycle arrest through ROS accumulation.

Summary: Pancreatic ductal adenocarcinoma (PDAC) is aggressive and requires improved therapies. Recent research has shown that autophagy, a macrometabolic process, is upregulated in PDAC and essential for its growth. However, the clinical efficacy of autophagy inhibition as a monotherapy is limited. Targeting both insulin-like growth factor 1 receptor (IGF1R) and pathways that oppose autophagy, such as the ERK-MAPK axis, can enhance the effectiveness of autophagy inhibitors in PDAC.

Summary: This article investigates the toxic effects of hydroxychloroquine (HCQ) on the inner retina and its impact on visual functions. Through a clinical study and a mouse model, the researchers found that chronic HCQ toxicity results in the loss of inner retinal neurons and retinal ganglion cells, leading to compromised visual functions. They also provided insights into the underlying molecular mechanisms involving autophagy-lysosomal defects and alterations in sphingolipid metabolism.

Summary: Pancreatic polypeptide cell hyperplasia (PPY-H) is a multiplication of neuroendocrine cells producing pancreatic polypeptide (PPY). The development and role of PPY-H still need to be further elucidated. This study analyzed 12 cases of PPY-H accompanying pancreatic neuroendocrine neoplasias (NEN) and found that gastrointestinal symptoms may be more related to PPY-H rather than NEN hormonal production. Strong SSTR2 expression in PPY-H suggests the potential utility of radiotracers in clinical diagnostics, but further studies are needed.

Summary: Understanding the molecular pathways behind cardiovascular illnesses is crucial. Recent studies have revealed the role of Xist RNA in cardiovascular diseases, including epigenetic changes, gene expression, cellular identity, and sex chromosomal inactivation. Dysregulation of Xist RNA expression is associated with conditions such as atherosclerosis, hypertrophy, and cardiac fibrosis.

Summary: Tescalcin (TESC) is upregulated in esophageal squamous carcinoma (ESCC) and is associated with poor prognosis, tumor infiltration, staging, and lymph node metastasis. TESC promotes proliferation, invasion, migration, and epithelial-mesenchymal transition (EMT) progression in ESCC, as well as activates the AKT pathway. TESC may serve as a prognostic factor and provide a new therapeutic strategy for ESCC.
