Objective To explore the role of RAS/PI3K pathway in the impairment of long-term potentiation （LTP） induced by acute aluminum （AI） treatment in rats in vivo. Methods First, different dosages of aluminum-maltolate complex [Al（mal）3] were given to rats via acute intracerebroventricular （i.c.v.） injection. Following AI exposure, the RAS activity of rat hippocampus were detected by ELISA assay after the hippocampal LTP recording by field potentiation technique in vivo. Second, the antagonism on the aluminum-induced suppression of hippocampal LTP was observed after the treatment of the RAS activator epidermal growth factor （EGF）. Finally, the antagonism on the downstream molecules （PKB activity and the phosphorylation of GluR1 $831 and $845） were tested by ELISA and West-blot assays at the same time. Results With the increasing aluminum dosage, a gradually decreasing in RAS activity of the rat hippocampus was produced after a gradually suppressing on LTP. The aluminum-induced early suppression of hippocampal LTP was antagonized by the RAS activator epidermal growth factor （EGF）. And the EGF treatment produced changes similar to those observed for LTP between the groups on PKB activity as well as the phosphorylation of GluR1 S831 and s845. Conclusion The RAS-PI3K/PKB-GluR1 S831 and S845 signal transduction pathway may be involved in the inhibition of hippocampal LTP by aluminum exposure in rats. However, the mechanisms underlying this observation need further investigation.

Objective To explore the effects of exposure to aluminum （AI） on long-term potentiation （LTP） and AMPA receptor subunits in rats in vivo. Methods Different dosages of aluminum-maltolate complex [Al（mal）3] were given to rats via acute intracerebroventricular （i.c.v.） injection and subchronic intraperitoneal （i.p.） injection. Following AI exposure, the hippocampal LTP were recorded by field potentiation technique in vivo and the expression of AMPAR subunit proteins （GluR1 and GluR2） in both total and membrane-enriched extracts from the CA1 area of rat hippocampus were detected by Western blot assay. Results Acute AI treatment produced dose-dependent suppression of LTP in the rat hippocampus and dose-dependent decreases of GluRz and GluR2 in membrane extracts; however, no similar changes were found in the total cell extracts, which suggests decreased trafficking of AMPA receptor subunits from intracellular pools to synaptic sites in the hippocampus. The dose-dependent suppressive effects on LTP and the expression of AMPA receptor subunits both in the membrane and in total extracts were found after subchronic AI treatment, indicating a decrease in AMPA receptor subunit trafficking from intracellular pools to synaptic sites and an additional reduction in the expression of the subunits. Conclusion Al（mal）3 obviously and dose-dependently suppressed LTP in the rat hippocampal CA1 region in vivo, and this suppression may be related to both trafficking and decreases in the expression of AMPA receptor subunit proteins. However, the mechanisms underlying these observations need further investigation.

Objective To investigate the impact of sub-chronic Aluminium-maltolate [Al（mal）s] exposure on the catabolism of amyloid precursor protein （APP） in rats. Methods Forty adult male Sprague-Dawley （SD） rats were randomly divided into five groups： the control group, the maltolate group （7.56 mg/kg BW）, and the Al（mal）s groups （0.27, 0.54, and 1.08 mg/kg BW, respectively）. Control rats were administered with 0.9% normal saline through intraperitoneal （i.p.） injection. Maltolate and Al（mal）s were administered to the rats also through i.p. injections. Administration was conducted daily for two months. Rat neural behavior was examined using open field tests （OFT）. And the protein expressions and their mRNAs transcription related with APP catabolism were studied using enzyme-linked immunosorbent assay （ELISA） and real-time polymerase chain reaction （RT-PCR）. Results The expressions of APP, 13-site APP cleaving enzyme 1 （BACEI） and presenilin-1 （PSi） proteins and their mRNAs transcription increased gradually with the increase of Al（mal）3 doses （P〈0.05）. The enzyme activity of BACEI in the 0.54 and 1.08 mg/kg Al（mal）s groups increased significantly （P〈0.05）. The expression of 8-amyloid protein （AS） 1-40 gradually decreased while the protein expression of A81-42 increased gradually with the increase of Al（mal）s doses （P〈0.05）. Conclusion Result from our study suggested that one of the possible mechanisms that Al（mal）s can cause neurotoxicity is that Al（mal）s can increase the generation of A81-42 by facilitating the expressions of APP, β-, and γ-secretase.

In 2014,a case of a worker diagnosed with Alzheimer’s disease(AD)following occupational exposure to aluminum(Al)was first reported by British scientist Christopher Exley[1].This patient had an early onset and a shorter course than the average person,indicating that Al may be an important environmental factor resulting in cognitive impairment.
