Journal: Targeting scleral remodeling and myopia development in form deprivation myopia through inhibition of EFEMP1 expression. (Pubmed Central) - Feb 20, 2024 Validation was performed using lentivirus-induced overexpression and shRNA targeting EFEMP1 in combination with LY294002, a PI3K inhibitor...In contrast, the AAV-mediated overexpression of EFEMP1 exacerbated the development of myopia and resulted in further thinning of collagen fibers in the posterior sclera. In summary, adjusting EFEMP1 concentrations could potentially serve as a viable approach to prevent and treat myopia by influencing the remodeling process of the posterior sclera.

Preclinical, Journal: Suppression of overactive IGF-1 attenuates trauma-induced heterotopic ossification in mice. (Pubmed Central) - Feb 19, 2024 Inhibitors of PI3K (LY294002) and mTOR (Rapamycin) both suppressed the IGF-1-stimulated mTOR signal and mitigated the formation of ectopic bones significantly. In conclusion, our results indicated that IGF-1 mediated the progression of traumatic HO through PI3K/Akt/mTOR signaling, and suppressing IGF-1 signaling cascades attenuated HO formation, providing a promising therapeutic strategy targeting HO.

Indeed, metabolomic analyses revealed defects of mitochondrial activity accompanied by anaerobic metabolism and inhibition of AMP-activated protein kinase (AMPK), which acts on metabolism and autophagy, rescues lysosomal defects. These results provide insights into the molecular mechanisms of MPS IIIB physiopathology, supporting the development of new promising approaches based on autophagy inhibition and metabolic rewiring to correct lysosomal pathology in MPSs.

Preclinical, Journal, IO biomarker: Design, synthesis, molecular docking, and in vitro studies of 2-mercaptoquinazolin-4(3H)-ones as potential anti-breast cancer agents. (Pubmed Central) - Feb 15, 2024 The relative gene expression of pro-apoptotic and anti-apoptotic genes revealed an overexpression of the P53 and BAX genes and a downregulation of the BCL-2 gene by real-time PCR. So, this work proved that compounds 3a, 3b, and 3e could be developed as anticancer candidates, via their P53-dependent apoptotic activity.

Preclinical, Journal: Ibrutinib-induced pulmonary angiotensin-converting enzyme activation promotes atrial fibrillation in rats. (Pubmed Central) - Feb 15, 2024 Importantly, we observed that perindopril significantly mitigated ibrutinib-induced left atrial remodeling and AF promotion by inhibiting the activation of the ACE and its downstream CSK-Src signaling pathway. These findings indicate that the Ibrutinib-induced activation of the ACE contributes to AF development and could serve as a novel target for potential prevention strategies.
- |||||||||| Journal: The Potential of PIP3 in Enhancing Wound Healing. (Pubmed Central) - Feb 14, 2024
Free PIP3 and the Q-starch/PIP3 complexes inherently activated the AKT signaling pathway, which is responsible for crucial wound healing processes such as migration; this was also observed in wound assays in mice. PIP3 was identified as a promising molecule for enhancing wound healing, and its ability to circumvent PI3K inhibition suggests possible implications for chronic wound healing.

QDTT also suppressed platelet secretion and "inside-out" GP IIb/IIIa activation by convulxin, along with inhibiting PI3K/Akt pathways. QDTT curtailed FeCl3-induced mesenteric thrombosis without significantly prolonging bleeding time, implying the potential of CEACAM1 A1 domain against platelet activation without raising bleeding risk, thus paving the way for novel antiplatelet drugs.

Together, these findings provide insights to guide strategies to overcome resistance in PIK3CA-mutated cancers.
- |||||||||| Review, Journal, Tumor mutational burden, PD(L)-1 Biomarker, IO biomarker, Synthetic lethality: Therapeutic Role of Synthetic Lethality in ARID1A-Deficient Malignancies. (Pubmed Central) - Feb 8, 2024
As ARID1A deficiency correlates with enhanced tumor mutability, microsatellite instability, high tumor mutation burden, increased programmed death-ligand 1 expression, and T-lymphocyte infiltration, ARID1A-deficient cells can be a potential therapeutic target for immune checkpoint inhibitors that warrants further exploration. In this review, we discuss the role of ARID1A in carcinogenesis, its crosstalk with other signaling pathways, and strategies to make ARID1A-deficient cells a potential therapeutic target for patients with cancer.

Finally, we demonstrate that targeting of the cell adhesion molecule ?1 integrin on top of Alpelisib sensitizes non-responders to radiochemotherapy. Taken together, our study demonstrates the sensitizing potential of Alpelisib and other PI3K inhibitors in HNSCC models and uncovers a novel ?1 integrin-dependent mechanism that may prove useful in overcoming resistance to PI3K inhibitors.

Other cellular events such as Caspase-7 overexpression and PI3K, AKT, PARP, and mTOR inhibition led to the apoptosis in hepatic cancer cells. The mRNA expression profile of PTEN, PI3K, AKT3, caspase-7, PARP and mTOR proteins, primarily controlling the cancer cell proliferation and apoptosis, suggest that exogenous supply of PTEN could regulate the expression of oncogenic proteins and thus cancer progression.
