GOLPH3, which is overexpressed in PRAD, may enhance glucose metabolic activity in PRAD cells in association with activation of the PI3K/AKT/mTOR pathway, thereby supporting PRAD cell proliferation. These findings provide basic mechanistic evidence for the role of GOLPH3 in PRAD cell metabolism, but further clinical studies are required to determine its prognostic or therapeutic relevance.

Furthermore, the PI3K/AKT inhibitor LY294002 enhanced the effects of sh-MUC1 on the proliferation, apoptosis, migration, invasion and EMT progress, while the activator SC79 partially restored these effects...To conclude, these findings suggested that MUC1 played an important role in lung cancer progression, potentially through the PI3K/AKT pathway. This positioned MUC1 as a molecule worthy of further investigation for its therapeutic potential.

EIF3B activated PI3K/AKT signaling and EMT, both of which were abolished by miR-124-3p or LY294002. These findings define the miR-124-3p/EIF3B/PI3K-AKT axis as a key regulator of OSCC progression and suggest EIF3B as a potential prognostic biomarker and therapeutic target.

Active macropinocytic uptake is essential for methuosis, as demonstrated by suppression with EIPA and Bafilomycin A1, whereas the AKT inhibitor MK2206 has no effect, establishing that direct PI3K inhibition, rather than AKT signaling, is required. In xenograft models, dietary restriction synergizes with Pictilisib to suppress tumor growth, correlating with pronounced intratumoral vacuolization. These findings reveal that combining PI3K inhibition with nutrient restriction converts cytostatic responses into methuosis-driven cytotoxicity via PI(4,5)P2-dependent macropinocytic dysregulation, providing a rational pharmacologic-dietary strategy to enhance PI3K-targeted cancer efficacy.

PI3K/AKT/mTOR pathway activity was examined by Western blot, and its function validated using SC79 (AKT activator) and LY294002 (PI3K inhibitor)...By modulating the PI3K/AKT/mTOR signaling axis and the pro-angiogenic microenvironment, ADGRD1 facilitates tumor growth and neovascularization. ADGRD1 may serve as a promising prognostic biomarker and therapeutic target for advanced BLCA.

Functional assays in vitro, along with in vivo experiments utilizing the PI3K inhibitor LY294002, confirm that LY6H promotes HCC cell proliferation through a mechanism involving the PI3K/AKT pathway and autophagy...Immunohistochemical analyses reveal positive correlations among LY6H, ATG3, Beclin1, PI3K, and AKT expression in HCC tissues, and their co-overexpression predicts an adverse prognosis. Collectively, this work uncovers a critical regulatory role of the LY6H-p-PI3K-autophagy axis in HCC progression, elucidates the molecular mechanisms underlying LY6H-mediated oncogenic effects, and identifies NSC243928 as a promising therapeutic candidate for targeting LY6H in HCC.

New TANs-related biomarkers have been found that effectively forecast the prognosis of patients suffering from PAAD.

Combining SDUY104 with an ERK inhibitor Ulixertinib produced synergistic antiproliferative activity via enhanced MAPK suppression. In a PANC-1 xenograft model, combination of SDUY104 with BKM-120 exhibited superior antitumor activity compared to either monotherapy. Collectively, this study identifies a potent SHP2 allosteric inhibitor and delineates a critical compensatory signaling mechanism underlying resistance to SHP2-targeted therapy, providing proof-of-concept support for pancreatic cancer treatment.

In addition, mTOR pathway activity and responsiveness to mTOR inhibitors (rapamycin and ipatasertib) and chemotherapeutic agents (cisplatin) were assessed. Compared with 2D monolayer cultures, 3D TMSs exhibited reduced mTOR signaling activity, which led to significantly decreased sensitivity to mTOR inhibition. These findings indicate that 3D bioprinted breast cancer models recapitulate key structural and signaling features of in situ tumors more accurately than 2D systems, highlighting their potential value for preclinical drug testing and mechanistic studies.

IL-22 promotes LUAD progression by activating the PI3K/AKT signaling pathway and inducing EMT, while its upregulation is modulated by promoter hypomethylation and miR- 21-5p suppression. The IL-22/PI3K/AKT axis represents a potential therapeutic target for LUAD management.

This nine-BRM prognostic model serves as a potential prognostic stratification tool that may complement existing clinical parameters in evaluating the outcomes of KIRC patients.
