In #PI3K inhibitor-resistant #BreastCancer, aberrant #mTORC1 suppresses #autophagy, creating #MetabolicStress that sensitizes #tumors to #metabolicdrugs, while p-4E-BP1 and p62 accumulation serve as poor-survival #biomarkers.

Persister cells reactivated multiple signaling survival pathways, including #MAPK, #PI3K/ #AKT and #mTOR. #CDK1 activity increased markedly, and inhibiting CDK1 significantly reduced persister cell survival and regrowth.
This review explores the #PI3K signaling pathway and its role in reshaping #CellSignaling, #MetabolicProcesses, and the #TumorMicroenvironment, highlighting emerging #therapeutic strategies for #PIK3CA-mutant #Tumors. #medsky

Congrats to the newly minted Dr. Ge @xiangyuge.bsky.social for defending her thesis today! A tour de force talk on her work unraveling signaling interactions between #PI3K and #KRAS. @yalecancer.bsky.social. Check out her preprint: www.biorxiv.org/content/10.1...
#GeparPiPPa #GBG105 investigates #neoadjuvant #endocrine therapy in combination with #trastuzumab and #pertuzumab, with or without the #PI3K inhibitor #inavolisib, in patients with HER2-positive, HR-positive, PIK3CA-mutated primary breast cancer.

🔥 Hot Off the Press | Low-dose #Aspirin & #PI3K -altered #Colorectal #Cancer
📊 3-year recurrence:
Group A: 7.7% (aspirin) vs 14.1% (placebo)
Group B: 7.7% vs 16.8%
✅ Low-dose aspirin reduces recurrence & improves disease-free survival in PI3K-altered tumors.

Tamoxifen Linked to Uterine Cancer via Direct PI3K Activation
A study in Nature Genetics finds tamoxifen can directly activate the PI3K pathway, bypassing PIK3CA mutations, which may explain its association with uterine cancer. Read more: getnews.me/tamoxifen-linked-to-uter... #tamoxifen #pi3k #uterine
Way to go, @xiangyuge.bsky.social, for a fantastic talk on how #PI3K governs resistance to #KRAS inhibition in #PancreaticCancer cells @faseborg.bsky.social Protein Phosphorylation! @yalepathology.bsky.social @yalecancer.bsky.social. Check out her preprint: www.biorxiv.org/content/10.1...
7/ 🧠 Big picture:
Our findings reveal that #PI3K can act upstream of wild-type RAS to mediate resistance to #KRAS inhibition.
This refines our understanding of #RAS pathway plasticity and provides new insights into #DrugResistance mechanisms.

We're delighted to share the journey of #PI3K inhibitors: a 20-year effort from teams at the ICR, The Royal Marsden, industry partners, funders and an ICR spinout company.
The results of a major trial confirmed the potential of Roche‘s PI3K inhibitor inavolisib in patients with #BreastCancer.
This study demonstrated that #AtrialNatriureticPeptide (ANP) mitigates #myocardial #IschemiaReperfusion (I/R) injury by downregulating Zn2⁺ transporter 8 (ZnT8) through the #PI3K signalling pathway and modulating Zn2⁺ homeostasis.

"The FDA has approved Genentech’s inavolisib (Itovebi) in combination with the CDK4/6 inhibitor palbociclib and the oestrogen-receptor antagonist fulvestrant for endocrine-resistant, PIK3CA-mutated, hormone receptor-positive, HER2-negative breast cancer." #PI3K

Our latest paper reveals an intriguing and essential role for the class III #PI3K VPS34 in Treg homeostasis and function. Selective deletion of VPS34 in Treg led to a scurfy-like phenotype, suggesting an essential role for VPS34 in Treg-suppression.
