Background: It has been previously reported that one copy of the variable number tandem repeat (VNTR) B alleles of the GPIbα gene increases the risk of non-arteritic ischaemic optic neuropathy (NAION) and the second eye involvement. This is the first case where the presence of both alleles is associated with bilateral NAION.
Case Presentation: A 52-year-old male presented with loss of vision in one eye and was diagnosed with NAION. The following year, he suffered another attack of NAION in the fellow eye. Genetic testing showed that he had both copies of VNTR B alleles of the GPIbα gene.
Conclusions: We report a case of bilateral NAION in the presence of two copies of VNTR B alleles of the GPIbα gene. This may have further implications for the function of platelet glycoproteins.

Heritable fragile bone disorders (FBDs), ranging from multifactorial to rare monogenic conditions, are characterized by an elevated fracture risk. Validating causative genes and understanding their mechanisms remain challenging. We assessed a semi-high throughput zebrafish screening platform for rapid in vivo functional testing of candidate FBD genes.

The occurrence of external L-glutamate at the Arabidopsis root tip triggers major changes in root architecture, but the mechanism of -L-Glu sensing is unknown. Members of the family of GLUTAMATE RECEPTOR-LIKE (GLR) proteins are known to act as amino acid-gated Ca-permeable channels and to have signalling roles in diverse plant processes. To investigate the possible role of GLRs in the root architectural response to L-Glu, we screened a collection of mutants with T-DNA insertions in each of the 20 AtGLR genes.

Developmental biologists can perform studies that describe a phenomenon (descriptive work) and/or explain how the phenomenon works (mechanistic work). There is a prevalent perception that molecular/genetic explanations achieved via perturbations of gene function are the primary means of advancing mechanistic knowledge. We believe this to be a limited perspective, one that does not effectively represent the breadth of work in our field.

Objective: Colorectal Cancer (CRC) has attracted much attention due to its high mortality and morbidity. Cordycepin, also known as 3'-deoxyadenosine (3'-dA), exhibits many biological functions, including antibacterial, anti-inflammatory, antiviral, anti-tumor, and immunomodulatory effects. It has been proven to show anticancer activity in both laboratory research studies and living organisms.

Introduction/objective: Plants and their bioactive compounds play a crucial role in the pharmaceutical industry for treating cancer. To date, the cytotoxic and antiproliferative effects of Hypericum perforatum methanol extract on human thyroid cancer cell lines have not been thoroughly explored. The present study aimed to assess the potential anti-cancer effects of HPME on human thyroid cancer and investigate its potential therapeutic benefits.
