The phosphatidyl inositol-3 kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamycin (mTOR) signaling have been associated with many cellular physiological events such as proliferation, maturation, survival, and metabolism. Besides their roles in normal cells, the pathway is often upregulated in various cancers. Due to their prominent roles in the cancer progression events, it is now being considered a target for cancer therapy and cancer chemoprevention.

The present review provides a concise outline of the role of the PI3K/Akt/mTOR pathway in carcinogenesis and progression events, including metastasis, drug resistance, and stemness. Further, emphasis is given to the PI3K/Akt/mTOR pathway inhibitory potentials of various food-derived bioactive components in cancer prevention.

Data on the PI3K/Akt/mTOR inhibiting natural products and their bioactive compounds have been obtained from PubMed/Medline, Scopus, Eurekaselect, etc. Findings from the above citation databases from 2000-2021 are includtary intervention may prove highly effective.Alzheimer's disease (AD) is the most prevalent dementia in the elderly, causing disability, physical, psychological, social, and economic damage to the individual, their families, and care- givers. Studies have shown some spices, such as saffron, rosemary, cinnamon, turmeric, and ginger, have antioxidant and anti-inflammatory properties that act in inhibiting the aggregation of acetylcholinesterase and amyloid in AD. For this reason, spices have been studied as beneficial sources against neurodegenerative diseases, including AD. In this sense, this study aims to present a review of some spices (Saffron, Rosemary, Cinnamon, Turmeric and Ginger) and their bioactive compounds, most consumed and investigated in the world regarding AD. In this article, scientific evidence is compiled in clinical trials in adults, the elderly, animals, and in vitro, on properties considered neuroprotective, having no or negative effects on neuroprotection of these spices and their bioactive compounds. The importance of this issue is based on the pharmacological treatment for AD that is still not very effective. In addition, the recommendations and prescriptions of these spices are still permeated by questioning and lack of robust evidence of their effects on neurodegeneration. The literature search suggests all spices included in this article have bioactive compounds with anti-inflammatory and antioxidant actions associated with neuroprotection. To date, the amounts of spice ingestion in humans are not uniform, and there is no consensus on its indication and chronic consumption guarantees safety and efficacy in neuroprotection. Therefore, clinical evidence on this topic is necessary to become a formal adjuvant treatment for AD.
Transdermal patches are convenient to use, especially in patients with Alzheimer's disease (AD)-associated dementia. However, various identified risks of errors in ad- ministering the patches cannot be disregarded. Patient Reminder Cards (PRCs, included a Medica- tion record sheet [MRS]) have been recently introduced as a risk minimisation tool to prevent incor- rect patch use (IU).

This study aimed to assess the effectiveness of PRCs to prevent IU and to investigate the dose titration pattern of rivastigmine patches in a real-world setting.

This multinational, observational, 11-month study included patients with AD currently using rivastigmine patches (4.6 mg/day, 9.5 mg/day, 13.3 mg/day) accompanied by a caregiver. Study outcomes were IU, including multiple patch use (MPU), incorrect patch placement, other IUs, perceived usefulness of the PRCs, and titration patterns of the patches.

Of the total 614 patients included, most were aged ≥65 years and had mild-to-moderate AD. Before and during the study, 27.7% and 18.0% of patients reported IU, respectively. Most pa- tients used MRS, and 73.5% rated it 'helpful' and reported lower rates of IU than those who report- ed it 'not helpful' (13.9%-16.5% vs. 20.2%). Overall, 141 patients had dose titrations, with 75.8% being up-titrated from 4.6 mg/day to 9.5 mg/day after a mean duration of 58 days. Safety findings were consistent with the established profile for the rivastigmine patch.

PRC was effective as a risk minimisation tool in limiting the inappropriate use of ri- vastigmine patches. The majority of patients requiring dose-change were up-titrated to 9.5 mg/day patches.

The interplay between phase II enzymes and efflux transporters leads to extensive metabolism and low systemic bioavailability of flavonoids.

The study aims to investigate the dynamic interplay between multiple UGTs and multiple efflux transporters inside the cells.

A new HeLa-UGT1A9-MRP3 cell was established to overexpress two dominant efflux transporters MRP3 and BCRP, and two UGT isoforms UGT1A9 and UGT1A3. The metabolism and glucuronides excretion for a model flavonoid genistein were determined in HeLa-UGT1A9-MRP3 cells and HeLa-UGT1A9-Con cells that overexpressed one UGT (1A9) and one efflux transporter (BCRP).

The excretion rate grew nearly 6-fold, cellular clearance of glucuronides increased about 3-fold, and a fraction of genistein metabolized (fmet) increased (14%, p<0.01) in the new cells. Sodium ascorbate cost Small interfering (siRNA)-mediated MRP3 functional knockdown resulted in markedly decreases in the excretion rates (26%-78%), intracellular amounts (56%-93%), cellular clearance (54%-96%) in both cells, but the magnitude of the differences in HeLa-UGT1A9-Con cells were relatively small. Reductions in fmet values were similarly moderate (11%-14%). In contrast, UGT1A9 knockdown with siRNA caused large decreases in the excretion rates (46%-88%), intracellular amounts (80%-97%), cellular clearance (80%-98%) as well as fmet value (33%-43%, p<0.01) in both UGT1A9 cells. Comparisons of the kinetic parameters and profiles of genistein glucuronidation and UGT mRNA expression suggest that HeLa-UGT1A9-MRP3 has increased expression of both MRP3 and UGT1A3.

The newly engineered HeLa-UGT1A9-MRP3 cells are an appropriate model to study the kinetic interplay between multiple UGTs and efflux transporters. It's a promising biosynthetic tool to obtain flavonoids glucuronides of high purity.
