Mutations in retinal primary cilia are responsible for human blindness but the mechanisms are not fully understood (Wheway et al., 2014). Characterizing the proteome of an organelle such as cilia, is a fruitful way to understand its function but methods often require considerable sample quantities. Here we develop a method to isolate the primary cilia of photoreceptor cells from bovine retinas. Through LC/MS/MS proteomics analysis we identify proteins enriched for cilia function including ciliopathy disease. This study shows our method can be used to isolate retinal primary cilia to obtain sufficient quantities of native protein samples.

An early diagnosis of Parkinson's disease (PD) represents a challenge and novel accurate biomarkers are therefore urgently needed. Detection of phosphorylated α-synuclein (p-α-syn) in skin nerve fibers has shown promise as such a marker. However, its accuracy for the identification of PD among patients with early signs of parkinsonism has not been thoroughly explored.

Objectives: Osteoarthritis (OA) is one of the most common chronic degenerative diseases, with chondrocyte apoptosis and extracellular matrix (ECM) degradation as the major pathological changes. The mechanical stimulation can attenuate chondrocyte apoptosis and promote ECM synthesis, but the underlying molecular mechanisms remain unclear. This study aims to investigate the role of primary cilia (PC) in mediating the effects of mechanical stimulation on OA progression.

ARL13B is a regulatory GTPase enriched in cilia, making it a popular marker for this organelle. Arl13bhnn/hnn mice lack ARL13B expression, die during midgestation, and exhibit defects in ciliogenesis. The R26Arl13b-Fucci2aR biosensor mouse line directs the expression of fluorescently tagged full-length Arl13b cDNA upon Cre recombination.

Cilia are membrane-covered hair-like organelles built on specialized centrioles and conserved throughout eukaryotic evolution. They are either motile or immotile, serving respectively as versatile signaling antennae or elegant beating nanomachines. Accordingly, their dysfunctions cause a wide variety of developmental and degenerative disorders, which in human are syndromes termed ciliopathies.

Bardet-Biedl Syndrome (BBS) is a rare autosomal recessive ciliopathy characterized by genetic heterogeneity. Despite significant progress in understanding the BBSome-coding genes associated with ciliopathies, the pathogenesis linked to mutations in chaperonin-coding genes (BBS6, BBS10, and BBS12) remains poorly defined. This study aims to confirm the genetic diagnosis of BBS and elucidate the pathological mechanisms in causative genes of BBS10 and BBS12.
