(Pubmed Central) - May 21, 2021 In addition, they are about to become a part of adjuvant treatment for patients with high-risk luminal disease based on positive results from the first randomized phase 3 trial on abemaciclib...Here we review current evidence from pro- and retrospective studies and give an outlook on future developments with respect to novel therapeutic agents, including oral SERD and AKT inhibitors, which have the potential to change the therapeutic landscape in the future. Furthermore, clinical treatment algorithms and current research will also be discussed.

[VIRTUAL] Approaches to Therapy of Richter Syndrome (LEVEL 4, GRAND BALLROOM G-L) - May 20, 2021 - Abstract #SOHO2021SOHO_170; P2 Conclusions Relapsed/refractory patients with CLL on novel agents are a new high-risk prognostic group with an extremely adverse outcome upon transformation. An international and common effort in developing preclinical models, prognosticators, biobanks, and databases should be pursued to improve outcomes in patients with RS.

Targeting the p53-HDM2 Axis KRT-232 is a first-in-class, potent, bioavailable inhibitor of HDM2 (key negative regulator of p53) that was assessed in a phase 2 study (KRT-232-101) and showed promising clinical efficacy and tolerability in TP53-wild type patients with MF who failed ruxolitinib treatment.17 A randomized phase 3 trial comparing KRT-232 (240 mg on days 1–7/28-day cycle) to BAT in MF patients refractory /resistant to JAK inhibitors has been launched...In the phase 2 study IMbark, the higher dose of imetelstat (9.4 mg/ kg) yielded a median overall survival of 29.9 months in patients with intermediate-2 or high-risk MF relapsed/refractory to JAK inhibitors.18 In light of the aforementioned promising result, a pivotal international phase 3 trial (IMpactMF) was launched to evaluate the survival advantage – an unprecedented trial endpoint for investigational MF medications – that imetelstat may confer to JAK-inhibitor-refractory MF patients.19 Conclusions The era of JAK1/2 inhibitor monotherapies in MF has ushered the way to the clinical development of a suite of promising novel medications spanning various biological mechanisms (for example, inhibitors of BET, HDM2, BCL-2/ BCL-XL, and telomerase, among others). Several highly promising candidates are currently evaluated in regulatory phase 3 clinical trials in the frontline and second line settings; these studies may lead to approval of novel medications that will significantly improve the current MF treatment paradigm.

Clinical, Journal: Aberrant cell migration contributes to defective airway epithelial repair in childhood wheeze. (Pubmed Central) - May 20, 2021 Importantly, the FDA-approved drug celecoxib - and its non-COX2-inhibiting analogue, dimethyl-celecoxib - stimulated the PI3K/Akt-integrin α5β1 axis and restored airway epithelial repair in cells from children with wheeze...Collectively, these results identify airway epithelial restitution via targeting the PI3K/Akt-integrin axis as a novel therapeutic avenue for childhood wheeze and asthma. We propose that the next step in the therapeutic development process should be a proof-of-concept clinical trial since relevant animal models to test the crucial underlying premise are unavailable.
- |||||||||| Journal: GREB1 regulates PI3K/Akt signaling to control hormone-sensitive breast cancer proliferation. (Pubmed Central) - May 20, 2021
Critically, growth suppression of estrogen-dependent breast cancer cells by GREB1 knockdown is rescued by expression of constitutively activated Akt. Together, these data identify a novel molecular function by which GREB1 regulates breast cancer proliferation through Akt activation and provides a mechanistic link between estrogen signaling and the PI3K pathway.

Taken together, MNNG&HPV regulates autophagy and further accelerates cell appreciation by activating the p62/KEAP1/NRF2 and PI3K/AKT/mTOR pathway. MNNG&HPV may improve Het-1A cell autophagy to contribute to excessive cell proliferation, reduced apoptosis, and protection from oxidative damage, thus accelerating the process of cell malignant transformation and leading to cancerous cells.

Finally, we show that the regulatory subunit p85β counteracts the conjugation of SUMO to p110β. In summary, our data reveal that SUMO is a novel p110β interacting partner with a positive effect on the activation of the PI3K pathway.

Review, Journal, PARP Biomarker, IO biomarker: AKT Inhibitors: New Weapons in the Fight Against Breast Cancer? (Pubmed Central) - May 20, 2021 As such, trials combining capivasertib and ipatasertib with CDK4/6 inhibitors, immune checkpoint inhibitors, and PARP inhibitors are currently ongoing. This review summarizes the available evidence on AKT inhibition in breast cancer, reporting both efficacy and toxicity data from clinical trials along with the available translational correlates and then focusing on the potential use of these drugs in new combination strategies.

Moreover, the EC9706 xenograft model further confirmed that CAR can significantly inhibit tumour growth in vivo. In summary, CAR exhibited a strong anticancer effect on human oesophageal cancer cells and promoted apoptosis by inhibiting the PI3K/AKT signalling pathway, suggesting that CAR can be used as new strategy for oesophageal cancer treatment.

On the contrary, PI3K/AKT/mTOR role in AD is less characterized, even though recent evidence demonstrates the relevant function for mTOR pathway in the regulation of epidermal barrier formation and stratification. In this review, we provide the most recent updates on the role and function of PI3K/AKT/mTOR molecular axis in the pathogenesis of different hyperproliferative skin disorders, and highlights on the current status of preclinical and clinical studies on PI3K-targeted therapies.

Inhibition of PI3K-III activity or suppression of SARA-dependent TGFβ signaling markedly ameliorated the defective adult neurogenesis in WDR81-deficient mice. Taken together, these findings not only uncover the requirement for the WDR81-SARA-TGFβ axis in adult hippocampal neurogenesis, but also suggest that defective adult hippocampal neurogenesis contributes to the etiology of WDR81-related neurological diseases.

(Pubmed Central) - May 15, 2021 In vitro experiments further demonstrated that DHZCP markedly suppressed HSCs proliferation by downregulating PI3K/Akt, which exerted a synergistic effect with the PI3K inhibitor LY294002. To sum up, our results confirmed that DHZCP exerted an antifibrotic effect in the animal model through inactivating the PI3K/Akt pathway, thus protecting rats from liver injury.

(Pubmed Central) - May 15, 2021 To sum up, our results confirmed that DHZCP exerted an antifibrotic effect in the animal model through inactivating the PI3K/Akt pathway, thus protecting rats from liver injury. These findings provide insights into the role of autophagy in the cardioprotective effects of IBAN and the molecular mechanisms underlying autophagy induction by IBAN.

Preclinical, Journal: Tolerance induced by DHPG postconditioning is mediated by the PI3K/Akt/GSK3β signalling pathway in an in vitro model of cerebral ischemia. (Pubmed Central) - May 15, 2021 DHPG PostC also induces a transient increased in GSK3β phosphorylation and inactivation that is followed by nuclear accumulation of β-catenin, that probably lead to the up-regulation of neuroprotective genes. Our results propose GSK3β as new target for neuroprotection, therefore, we verified that the two GSK3β inhibitors N-(3-Chloro-4-methylphenyl)-5-(4-nitrophenyl)-1,3,4-oxadiazol-2-amine (TC-G 24) and LiCl are neuroprotective agents in OGD and also can be used as PostC agents.
