Article Abstract
Blood malignancies remain a therapeutic challenge despite the development of numerous treatment strategies. The phosphatidylinositol-3 kinase (PI3K)/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway plays a central role in regulating many cellular functions, including cell cycle, proliferation, quiescence, and longevity. Therefore, dysregulation of this pathway is a characteristic feature of carcinogenesis. Increased activation of PI3K/Akt/mTOR signaling enhances proliferation, growth, and resistance to chemo- and immunotherapy in cancer cells. Overactivation of the pathway has been found in various types of cancer, including acute and chronic leukemia. Inhibitors of the PI3K/Akt/mTOR pathway have been used in leukemia treatment since 2014, and some of them have improved treatment outcomes in clinical trials. Recently, new inhibitors of PI3K/Akt/mTOR signaling have been developed and tested both in preclinical and clinical models. In this review, we outline the role of the PI3K/Akt/mTOR signaling pathway in blood malignancies' cells and gather information on the inhibitors of this pathway that might provide a novel therapeutic opportunity against leukemia.

Background: Bladder cancer is one of the most common malignancies of the urinary system. Despite significant advances in diagnosis and treatment, the compromised therapeutic effect of chemotherapeutic agents, such as Oxaliplatin (OXA), remains a major clinical challenge. Thus, a combination therapy is required to enhance the OXA's therapeutic effectiveness and improve patient outcomes.

PTEN, a tumor suppressor phosphatase, regulates cellular functions by antagonizing the growth promoting PI3K/Akt/mTOR pathway through the dephosphorylation of the second messenger PIP. Many preclinical cellular and animal studies have used PTEN inhibitors to highlight specific disease contexts where acute activation of PI3K/Akt/mTOR pathway might offer therapeutic advantages. In the present study we have re-evaluated first-generation PTEN inhibitors, including established bisperoxo-vanadium complexes (bpVs).

Peripheral nerve injury (PNI) as a common clinical issue that presents significant challenges for repair. Factors such as donor site morbidity from autologous transplantation, slow recovery of long-distance nerve damage, and deficiencies in local cytokines and extracellular matrix contribute to the complexity of effective PNI treatment. It is extremely urgent to develop functional nerve guidance conduits (NGCs) as substitutes for nerve autografts.

Ethnopharmacological Relevance: The classic TCM prescription, Shoutai Wan (STW), is extensively used in clinical settings to manage threatened miscarriage and Recurrent spontaneous abortion (RSA). The complexity of pregnancy physiology, coupled with diverse etiologies, and the specificity of energy metabolism for normal embryo attachment and development,pose challenges to clinical diagnosis and treatment. The specific molecular mechanisms of how STW regulates these biological processes and contributes to the treatment of RSA remain to be elucidated.

Prostate cancer (PC) ranks among the most prevalent cancers in males. Recent studies have highlighted intricate connections between long non-coding RNAs (lncRNAs), natural products, and cellular signaling in PC development. LncRNAs, which are RNA transcripts without protein-coding function, influence cell growth, programmed cell death, metastasis, and resistance to treatments through pathways like PI3K/AKT, WNT/β-catenin, and androgen receptor signaling.
