Name: Late stage results from the probe development efforts to identify selective agonists of the Transient Receptor Potential Channels 3 (TRPML3): fluorescence-based cell-based dose response assay for TRPML3 agonists (probe candidates and analogs, Round 3).
Description:
Cell signaling pathways that mediate osmosensation, photosensation, and thermosensation depend on a family of diverse transient receptor potential (TRP) cation channels, which are activated by agonist-receptor coupling (1-5). A role for these channels in inner ear hair cell mechanotransduction was gleaned from TRP channel mutations identified in flies, worms, and lower vertebrates with defective balance and impaired sensitivity to touch (1-5). TRPML3 (mucolipin 3; MCOLN3) is a TRP channel expressed in inner ear hair cells and stereocilia (5-7), suggesting it may play a role in hearing and mechanotransduction. Reports that mice with mutations in TRPML3 (known as varitint-waddler mutants) exhibit early-onset hearing loss accompanied by head-bobbing and circling behaviors (8-10), provide further support for a role of TRPML3 in hearing and vestibular function. As a result, the identification of selective probes for TRPML3 would be useful to investigate the function of TRPML3 in inner ear mechanotransduction and hearing biology (11).

Protocol
Assay Overview:
The purpose of this assay is to determine dose response curves for powder samples of compounds identified as possible selective TRPML3 agonist probe candidates. This assay may also have tested analogs of the above compounds. This assay employs a HEK293 cell line that stably expresses the human TRPML3-YFP cation channel. The cells are treated with test compounds followed by measurement of intracellular calcium as monitored by a fluorescent, cell permeable calcium indicator dye. As designed, compounds that act as TRPML3 agonists will increase calcium mobilization, resulting in increased relative fluorescence of the indicator dye and increased well fluorescence. Compounds were tested in triplicate using a 10-point, 1:3 dilution series starting at a nominal concentration of 29.9 uM.
Protocol Summary:
The TRPML3 HEK293 cell line was routinely cultured in T-175 sq cm flasks at 37 C and 95% relative humidity (RH). The growth media consisted of Minimum Essential Medium with GlutaMAX and supplemented with 10% v/v heat-inactivated qualified fetal bovine serum, 800 ug/mL Geneticin, and 1X antibiotic mix (penicillin, streptomycin, and neomycin). The day before the assay 1500 cells in 3 uL of growth media were seeded into each well of 1536 well microtiter plates and allowed to incubate at 37 C, 5% CO2, and 95 % RH for 23 hours. Next, 2 uL of the fluorogenic Fluo-8 intracellular calcium indicator mixture with 1 mM trypan red plus (prepared according to the manufacturer's protocol) was added to each well. After a 1 hour incubation at 37 C, 5% CO2, and 95 % RH followed by a 30 minute incubation at room temperature, the assay was started by performing a basal read of plate fluorescence (470-495 nm excitation and 515-575 nm emission) for 5 seconds on the FLIPR Tetra (Molecular Devices). Next, 15 nL of test compound in DMSO, DMSO alone (0.3% final concentration), or the cholinergic agonist carbachol (87 uM final concentration) in DMSO were dispensed to the appropriate wells. Then a real time fluorescence measurement was immediately performed for the remaining 120 seconds of the assay.
A ratio for each well was calculated to normalize assay data, according to the following mathematical expression:
Ratio = I_Max / I_Min.
Where:
I_Max represents the maximum measured fluorescence emission intensity over the 125 second read.
I_Min represents the minimum (basal) measured fluorescence emission intensity before compound was added.
The percent activation was calculated from the median ratio as follows:
%_Activation = ( ( Ratio_Test_Compound- Median_Ratio_Low_Control ) / ( Median_Ratio_High_Control - Median_Ratio_ Low_Control ) ) *100
Where:
Test_Compound is defined as wells containing test compound.
High_Control is defined as wells with carbachol.
Low_Control is defined as wells with DMSO.
For each test compound, percent activation was plotted against compound concentration. A four parameter equation describing a sigmoidal dose-response curve was then fitted with adjustable baseline using Assay Explorer software (Symyx Technologies Inc). The reported EC50 values were generated from fitted curves by solving for the X-intercept value at the 50% activation level of the Y-intercept value. In cases where the highest concentration tested (i.e. 29.9 uM) did not result in greater than 50% activation, the EC50 was determined manually as greater than 29.9 uM.
PubChem Activity Outcome and Score:
Compounds with an EC50 greater than 10 uM were considered inactive. Compounds with an EC50 equal to or less than 10 uM were considered active.
Any compound with a percent activity value <50% at all test concentrations was assigned an activity score of zero. Any compound with a percent activity value >50% at any test concentration was assigned an activity score greater than zero. Activity score was then ranked by the potency, with the most potent compounds assigned the highest activity scores.
The PubChem Activity Score range for active compounds is 100-75, and for inactive compounds 13-0.

Comment
This assay may have been run as two or more separate campaigns, each campaign testing a unique set of compounds. In this case the results of each separate campaign were assigned "Active/Inactive" status based upon that campaign's specific compound activity cutoff value. Possible artifacts of this assay can include, but are not limited to: dust or lint located in or on wells of the microtiter plate, compounds that non-specifically modulate calcium levels or channel activity, and compounds that quench or emit fluorescence within the well. All test compound concentrations reported are nominal; the specific concentration for a particular test compound may vary based upon the actual sample provided.
