Abstract:
Fragile X syndrome (FXS) is the most frequent inherited form of intellectual disability and autism spectrum disorder. Loss of the fragile X mental retardation protein, FMRP, engenders molecular, behavioral, and cognitive deficits in FXS patients. Experiments using different animal models advanced our knowledge of the pathophysiology of FXS and led to the discovery of many targets for drug treatments. In this review, we discuss the potential of metformin, an antidiabetic drug approved by the US Food and Drug Administration, to correct core symptoms of FXS and other neurological disorders in humans. We summarize its mechanisms of action in different animal and cellular models and human diseases.
Insights
Metformin, an antidiabetic drug, shows promise for treating Fragile X syndrome (FXS), a common cause of intellectual disability and autism. Research explores its potential to correct core FXS symptoms in humans.
Area of Science:
- Neuroscience
- Genetics
- Pharmacology
Background:
- Fragile X syndrome (FXS) is the leading inherited cause of intellectual disability and autism spectrum disorder.
- Loss of fragile X mental retardation protein (FMRP) causes molecular, behavioral, and cognitive deficits in FXS.
- Animal models have significantly advanced understanding of FXS pathophysiology and identified therapeutic targets.
Purpose of the Study:
- To review the potential of metformin, an FDA-approved antidiabetic drug, for treating core symptoms of FXS.
- To explore metformin's efficacy in other human neurological disorders.
- To summarize metformin's mechanisms of action in various models of FXS and other diseases.
Main Methods:
- Review of existing literature on FXS.
- Analysis of studies using animal and cellular models of FXS.
- Examination of clinical data on metformin's effects in neurological disorders.
Main Results:
- Metformin demonstrates potential in preclinical models to address FXS-related deficits.
- The drug's mechanisms of action are being elucidated across different disease models.
- Evidence suggests possible applications beyond diabetes.
Conclusions:
- Metformin represents a promising therapeutic candidate for Fragile X syndrome.
- Further investigation into metformin's neurological effects is warranted.
- Repurposing metformin could offer a novel treatment strategy for FXS and related disorders.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes.
