vision/eye
• CD45+ leukocyte infiltration is seen in the sub-conjunctival stroma 3-4 days after eyelid opening, at P16, of pups treated with doxycycline
• epithelial cells of the ocular surface of pups treated with doxycycline (via nursing moms) are hyperplastic and aberrantly desquamated from the conjunctiva
• pulse doxycycline induction from P0 to P16 results in mutants with severe ulceration and neovascularization in the cornea, even after 180 days post-doxycycline induction
• the aberrantly desquamated cells within the conjunctival sac are composed of conjunctival epithelial cells and basal cells of stratified epithelia but not corneal epithelial cells, indicating aberrant conjunctival, but not corneal, epithelial cell desquamation
• conjunctival epithelia from pups treated with doxycycline (via nursing moms) exhibit an increase in cell proliferation
• pups treated with doxycycline (via nursing moms) do not show signs of goblet cell differentiation from the conjunctival epithelium at P9 or P16 unlike controls
• adult mice administered doxycycline at P90 exhibit loss of goblet cells from the conjunctiva and cellular debris in the conjunctival sac
• pups from nursing moms administered doxycycline do not exhibit clear conjunctival sacs at P9 as in wild-type pups and instead have a mass of cell debris that is abnormally present in the conjunctival sac, indicating early ocular surface morphogenesis alterations
• adult mice administered doxycycline at P90 exhibit cellular debris in the conjunctival sac
• pups treated with doxycycline exhibit epidermal metaplasia of corneal epithelium at P16
• pulse doxycycline induction from P0 to P16 results in mutants with severe ulceration and neovascularization in the cornea, even after 180 days post-doxycycline induction

cardiovascular system
• pulse doxycycline induction from P0 to P16 results in mutants with severe ulceration and neovascularization in the cornea, even after 180 days post-doxycycline induction

immune system
• CD45+ leukocyte infiltration is seen in the sub-conjunctival stroma 3-4 days after eyelid opening, at P16, of pups treated with doxycycline

integument
• adult mice administered doxycycline at P90, exhibit hair loss one month after doxycycline induction, with random alopecia on the body, including the eyelid within 3 months
